What Engine Noise Is Normal?
A knocking or ticking noise from your engine is a sign that something is wrong.
Usually, it's because of one of these issues:
- There is a lack of lubrication
- Something has broken
- Something is about to break
Some engines have a normal ticking noise caused by electrical components like injectors, relays, and solenoids, and also the engine itself makes some noise turning thousands of RPM's (revolutions per minute), but for the most part, engines should generally have only a very soft ticking noise with no knocking noise.
If your engine develops a knocking noise while driving, usually it's quickly followed by a red or amber warning light on the dash notifying the driver there is a problem. If the light is red, I highly recommend shutting off the engine, red means STOP! If the light is amber, I recommend taking it easy until you reach a garage or service station, amber means CAUTION and the noise and light should be checked very soon by a reputable mechanic (not your cousin, unless they have a mechanical background).
If your engine develops a ticking or knocking noise in a short period, the first thing you should do is shut off the engine and check the oil level. You'll need to find the engine oil dipstick and see if you need to add oil or if the oil level is up to the full line. If you cannot find the dipstick, ask for help; don't chance driving without checking the oil level first.
Reasons Why the Oil Level Might Be Low
There are several reasons the oil level in your engine may be low. The most common cause is an oil leak. If you suspect you have an oil leak, check the ground where you usually park your car: most often you will find several drips or small puddles of oil on the ground or garage floor. If you cannot see any signs of leaks on the ground or garage floor, try placing a large piece of cardboard under the engine overnight and check for leaks in the morning. This method usually verifies an oil leak clearly without any questions.
Noises From The Upper and Lower Engine
I created this video below of some typical engine ticking and knocking noises. Some of the ticking noises are from the top of the engine where the camshaft is located; worn camshaft lobes are a common cause of upper engine tapping/ticking noises. Deeper knocking noises are from below where the crankshaft is located. Worn crankshaft and connecting rod bearings are the usual cause of lower-pitched, deep knocking noises but are not the only parts that can cause these types of noises. I had a vehicle in the shop that had a blown timing belt tensioner (see above), and this was a very heavy deep noise, so you just never know what is making the noise until you have a knowledgeable mechanic check it out.
Below the video are some pictures of a normal camshaft and another one that is worn causing some noise.

Camshaft Lobe: Normal and Damaged
You May Have an Internal Engine Oil Leak
If you don't see any visible external engine oil leaks, it's possible you are leaking oil internally. There are lots of possible sources of internal engine oil leaks like piston rings, valve guide seals, gaskets, and o-rings. If your engine is burning oil past the piston rings or valve guide seals, the usual sign is blue smoke exiting the exhaust pipe, some when the engine is idling and more when the engine is accelerating.
There is another type of internal engine oil leak called a head gasket leak. In some cases, the head gasket can leak engine oil into a cylinder, again causing blue smoke out the exhaust; it can also leak coolant into a cylinder and cause thick white smoke out the exhaust. One other possibility is coolant and oil mixed together internally causing a milky mess either in the oil pan or radiator. This type of leak is very noticeable: just pull the oil dipstick, or look in the coolant overflow tank, and if you see any contamination that looks like chocolate milk, you have found your problem.
If your oil is dark brown or amber, and your coolant shows no signs of oil mixing, but you still think you may have a possible internal engine oil leak, top off the oil to the full line on the dipstick, then check your oil level every 500 miles and document your findings.
Note: If the oil level is low when checking it after 500 miles, top it off again and recheck it in another 500 miles, this will give you an idea of how much oil you're losing or burning.
Blue Smoke From Exhaust = Internal Engine Oil Leak
What Is the Fix When Your Engine Makes These Noises?
Once an engine develops a noise like this, there is no easy fix. Typically, you'll need to dig deep into the engine to either fix the noise by replacing internal engine parts (camshaft or crankshaft) or replacing the complete engine. Once an engine runs low on oil to the point where the engine makes noise, it's usually too late; the damage is done.
Here is one tip of advice. If you never do any service to your vehicle, the one maintenance item you should always do is change your oil. The oil is the blood of your engine, and the engine is the heart of your car, just like the human body, take care of your heart, and the blood will keep pumping.

Questions & Answers
Question: There's a knocking noise coming from the engine area of my vehicle, but it only knocks when accelerated. Also, white smoke comes from the exhaust, but it's not overheating at all. After driving the blazer around the block a few times, the smoke isn't as bad. Any ideas as to what could be the problem?
Answer: The knocking on acceleration is most likely a worn crankshaft bearing, and the smoke is probably worn piston rings or valve guide seals. Valve guide seals will usually cause smoke on start up and then will disappear after driving for a few minutes; worn piston rings will smoke all the time.
Question: My car oil light came on in red is my engine damaged?
Answer: If the light cam on, it means you're low on oil. If the engine starts knocking and you add oil and it's still knocking, you have damaged the engine.
Question: I have a similar problem with my Toyota Hiace. Can I still drive it for short distances before getting a fix?
Answer: I recommend towing it because if the knock or ticking noise is extremely loud, the vehicle could leave you stranded.

Have you pulled the oil dipstick to verify the oil is full? Sometimes mechanics forget to top off the oil after doing a job like this, so that would be the first step. If the oil level is good, I recommend you contact the shop that performed the timing chain replacement and have them double-check their work. Keep me posted on what you find, thanks.
Dejan on August 26, 2020:
Hi. Recently my vehicle have been changed the timing chain and the tensioner. The day after the replacement i got a problem with the oil pressure. I have no oil pressure fow a couple of seconds on cold start. What can cause this problem?
Shawn on July 16, 2020:
I have a 2006 ford freestar 4.2 I had a lifter tick took apart found the collapsed lifter and installed the new hydrologic lifter after soaking in oil for 2 hours. once everything was back together started up and was still ticks there is no oil light on and no blue or white smoke just sounds rough I'm lost at this point
Eddie Carrara (author) from New Hampshire on June 22, 2020:
Who changed the oil pump because that's a pretty big job, usually the timing cover and oil pan need to be removed to replace it. Let me know if this is what got changed, and if you paid someone to replace it, how much did it cost? Thanks.
Jenna on June 20, 2020:
I have a Audi A3 1.8t 2011 model, I just changed my oil pump but the red warning signal for low oil pressure still pops up, my engine light and Epc light pops up. Theres a grinding metallic sound when exhilarating and now I just give up because I though all will be well with my car.
Can you perhaps give me a sense of direction as to what the problem can be.
Eddie Carrara (author) from New Hampshire on June 14, 2020:
Coolant sensors are not usually relays, just simple wax switches that don't normally click. Is the fuse box close by the switch or is anything else attached to the wire-harness in that area? I don't think the coolant switch is what's making your noise, I think the noise is traveling through the vehicle's body or the wire harness. Keep looking and let me know what you find, thanks :)
Ashlee on June 13, 2020:
My 2002 2.0 A/T VW new beetle has an intermittent ticking noise from the engine bay. At first I thought timing belt but I have gotten out n listened to the noise and have traced it down to the plug in connector (sensor?) where the coolant level is monitored on the overflow reservoir on the back passenger side of engine compartment. I can actually feel the clicking/ ticking whatever you want to call it when I touch the connector for the coolant level sensor. Any clue if there's some sort of relay in there that would cause this to click?
Eddie Carrara (author) from New Hampshire on June 13, 2020:
It sounds like either you're really low on oil or the engine overheated, so check your oil and coolant to see which is the culprit, but it sounds like the damage is done already. Let me know if I can answer any other questions for you.

It sounds like the serpentine belt is coming apart but that's just a guess. You'll need to confirm what the fluid is by comparing it to other fluids in the vehicle like power steering, transmission, oil, etc. Let me know what you find, thanks.
Eddie Carrara (author) from New Hampshire on May 16, 2020:
I recommend you check the serpentine belt and its tensioner for any damage, if everything looks ok you'll need to dig a little deeper. Let me know what you find, thanks.

My 2015 ford escape is making a knocking noise when at idle. It knocks even more if I turn the wheel. But if I step on the gas just a bit, it goes away. What could this be?

2003 Nissan 350z.
Today I got in the car to go to work and my fiancé said he heard a knocking sound when I started it, and then found pieces of rubber or wire around the under passenger side.. when I drove off he noticed a puddle of what he thinks may be oil but not 100% sure. I turned around and came home and took our SUV. I’m trying to find out what’s wrong with the car before taking it into a shop so I’m not surprised by a massive bill!!!
Eddie Carrara (author) from New Hampshire on April 28, 2020:
I would try topping off the oil and see if the noise disappears, I wouldn't run it too long, just enough to see if the noise is gone. If the noise subsides you could probably drive it to a mechanic, if not I recommend you have it towed just to be safe.
Dustin McDowell on April 27, 2020:
I have a 2012 Toyota Tacoma. Engine is making a rattle similar to shaking a can of spray paint or a kids toy machine gun when accelerating. I drove the truck home and now has been sitting. Seems to be oil leaking underneath and the dip stick is dry (although I got an oil change about 2 months ago). Do you think I can top up oil and drive to a mechanic? What do you think the issue is? Could I have permanently damaged my engine? Any advice would be appreciated! Thanks
Eddie Carrara (author) from New Hampshire on April 09, 2020:
I recommend you identify where the noise is coming from, top or bottom? It may not even be an internal tick/knock, it could be caused by a serpentine belt, external belt tensioner, timing chain/belt, or timing chain/ belt tensioner. If those look OK, then dig a little deeper but Identifying where the noise is coming from is crucial to prevent having to tear apart the complete engine. Let me know if this helps.
Kaleb Lewis on April 06, 2020:
I have a 2007 Hyundai sonata with 97k miles on it. One day It started to tick right when you crank it up and then goes away, between 2k-3k rpms it makes a louder constant ticking noise. I have the engine almost turn down im about to check the hydraulic lifters, valves, the seats, the cam bearings, fuel enjectors ect. If i dont find anything wrong im going to start on the bottom end. I just want a second opinion on this because i dont want to have to bored it out and get new pistons and rods and bearings.
Eddie Carrara (author) from New Hampshire on March 17, 2020:
I hope you didn't pay for any repairs on the timing chain because that would be included with the warranty piston ring job. I recommend you don't take the car back until the noise is completely gone and you may want to call the Honda Customer Relations # in your owners manual and let them know what your concerns are so they can contact the dealership and help move the process along a little faster for you, they may send out a field engineer to help diagnose the noise. Keep me posted on what you find, thanks.
Kaitlyn Wright on March 17, 2020:
Hey there, I have a 2012 Honda Insight that was just rebuilt by my local Honda dealership due to piston rings. They also replaced some worn bearings. Only had it for a few hours after picking it up from the dealership and on the second time driving it, the check engine light popped back on and the car began making a ticking noise, accompanied by what sounded like a massive exhaust leak. I immediately returned the car to Honda the following day and requested this be looked at, as obviously I did not drop my car off with those issues and it should not have these issues following a rebuild. They told me my timing chain was loose and hitting something, which was causing the noise. Which seemed odd to me, but my knowledge is in older cars so I went with it. Three weeks later they finally completed that repair and upon a test drive, discovered the noise was still present. They have absolutely no idea what it is and I’m searching for options as to what it could be while I wait to hear back from them.
Eddie Carrara (author) from New Hampshire on March 10, 2020:
It sounds like either you have low oil pressure or the oil pressure sensor is faulty. I recommend you have it towed to a shop to have it diagnosed just to be safe because if the oil pressure is low you could seize the engine. The smoke may be something totally unrelated but let the mechanic know about the smoke as well, it may help with the diagnosis. Let me know what you find, thanks.

Hello i have a 2003 gmc envoy,my check gauge engine oil pressure is low stop engine light comes on.but when I check the oil its say the oil is full.
I also have white smoke ever now and then coming from my pipe can you give mesome advice please
Eddie Carrara (author) from New Hampshire on February 28, 2020:
I recommend you start by replacing the brakes as needed and the serpentine belt. The old serpentine belt may be causing the noise on startup or it could be the belt tensioner. I Know the grinding noise will disappear but let's see if the knocking noise is any better with a new belt. Keep me posted on what you find, thanks.
Laurie on February 27, 2020:
Have a 2002 Buick Lasabre Custom. It makes a grinding noise in reverse and have noticed a bit of a knocking sound somewhere up front when it is first started. It needs breaks and serpentine belt changed.
Eddie Carrara (author) from New Hampshire on February 25, 2020:
Can you give me a few more details like the year, make, mileage, where the noise is coming from, when do you hear it, driving, idle, taking a corner, etc?
Jarvus Reese on February 22, 2020:
Why is my car ticking??
Eddie Carrara (author) from New Hampshire on February 17, 2020:
I recommend you top off the oil and have the leak checked asap. The radiator is supposed to get hot, usually 180* - 200* but if the temp gauge is getting hot you may have more then one problem. Let me know if this helps.
Pana on February 17, 2020:
Hi I’ve got a 94 kzn130 surf lost most of da coolant one drive n engine started getting hot I stopped n worked da problem out but now I’ve got either an oil or diesel leak coming from under the back of turbo area n on start makes a tapping noise haven’t lost any power n doesn’t blow any different smoke amount or colour but radiator seems to feel hot

It sounds like you may have a sticking RF caliper, the ticking noise is most likely the rotor cooling off because it's overheating, check out this video I made on sticking calipers and let me know if this is what you are experiencing. https://youtu.be/GInfvb6U48Q
Cristina on December 23, 2019:
Hi. I have a 2003 Honda CRV. 133,000 miles. Serviced religiously at suggested intervals. I have a ticking sound that remains several minutes after I turn the car off. It seems to be coming from the center/underside of car. I smell a slight burning smell from near my front right tire. all tires are new. I think it's coming from underside of engine/car? What do you think this could be? I took it back to mechanic but cant replicate sound and burning smell when I get to his shop.. Any ideas?

My Toyota Mark 2, engine is making a lot of noise when starting. the previous owner has never been servicing the can for so long. the engine makes a lot of noise and just notice the Engin head was full will sticky oils. Please advise what could be the problem and options to get it fix.
Eddie Carrara (author) from New Hampshire on September 24, 2019:
There are several things that can cause this. One may be a belt tensioner or serpentine belt that is worn. Another thing to check is for an exhaust leak, the noise can vary depending on engine temperature. Start there and let me know if you find anything.
Kellychancey on September 20, 2019:
I have a 2016 Dodge Ram truck and sometimes when I turn on the truck I hear a ticking sound that sounds like it is coming from under the hood. If I rev the engine it goes away. If I turn off the truck then turn it back on it goes away, and sometimes you don't hear it all all. Before this started I had just had it in for an oil change at pep boys. I guess the ticking sound started 2 weeks after oil change, and yet it doesn't do it all the time. There are no warning lights on the dash board, and it's not really loud. It will do it while driving as well unless I turn engine back off and restart.

I Have a 2009 Porsche Cayenne Turbo S and just recently it has stopped working. The car will no longer turn over unless it is hooked up to a battery booster and after it does turn there is a horrible knocking sound that gets worse with revs. We had the car towed to a dealership that said the whole engine had to be replaced. Without any mechanical knowledge I was hoping this wouldnt be the diagnosis. If you have any insight on what it could be that would be very helpful

Eddie Carrara (author) from New Hampshire on July 08, 2019:
I recommend you check the oil level often. The noise you described sounds to me like you may have internal engine damage because of the lack of oil.
Josie valdez on July 07, 2019:
When i start my car it has a loud knocking sound and if i push on the gas it gets louder..Mind you it is burning oil..
Eddie Carrara (author) from New Hampshire on July 02, 2019:
It sounds like your family member may have run the engine low on oil and caused some internal damage. I recommend you check the oil level and make sure the battery is fully charged, then try to start it. It sounds like the damage is already done and you have nothing to loose.
Eddie Carrara (author) from New Hampshire on July 02, 2019:
I recommend you check the coolant level, it sounds to me like you may be burning coolant and it could be causing all your issues. Let me know what you find, thanks.
Eddie Carrara (author) from New Hampshire on July 02, 2019:
It sounds to me like your timing chain may be stretched causing the noise, the oil consumption may be a leak (if you notice a lot of oil on the ground everywhere you park or it could be burning oil past the piston rings. Do you see any blue smoke out the tailpipe?
Alex R. on June 25, 2019:
I have an 02 nissan altima, it has 76k miles on it. The car is burning oil about every 500 miles i have to top it off and i notice the oil gets dark but not milky. And when i i cold start it the timing chain makes a grind noise at startup, but once the car is warmed up and has been driven the grind goes away. I was told i have a bad rear main seal, so i got the barss sealer that you add to the oil and it still burns oil. Id like to know your opinion on this please, and if the hydraulic tensioner has anything to do with it. Oh and i also replaced the pcv valve. Thanks.
Davida on June 25, 2019:
Hi, I notice what seem to be white spoke coming out of my car when I accelerate with a knocking sound on the right top side of my engine. My husband checked my oil and made sure there was oil in my care, but today I am still having the same issue. I am noticing also today some lag in my car when I drive it. I also notice that when I am parked and accelerate the gas the knocking sound is not there and neither is the smoke.
Peter G. on June 23, 2019:
I left my car to a family member and they never changed the oil and they started hearing a loud knock and they continued driving the car like that. Now my car doesn’t even want to turn on any idea what it might of been or what it is

Eddie Carrara (author) from New Hampshire on May 21, 2019:
If you have smoke coming from the tailpipe and your using oil, it's possible you're burning oil past the piston rings. It may be time for a rebuild but in the meantime keep an eye on your oil or you could do more damage.
Eddie Carrara (author) from New Hampshire on May 21, 2019:
Wish I could help build moral ha. That is a tough one, I recommend checking all wires that could have gotten pinched during the swap, check all connectors for soft set/lose fit or loose pins pushed out, be sure all your grounds are clean and tight. It may sound silly but we find a lot of problems are man-made and difficult to find, so start with the basics. Let me know if you find anything, thanks.

I have a 2014 Ford Fiesta ST 1.6 Ecoboost.
Recently had a new engine installed, myself and my mechanic are slowly getting stumped. It keeps coming up with 0016 and 0017 error codes which relate to Cam sensor Correlation issues.
He has checked and re-timmed the engine twice, replaced all associated sensors and the top and bottom pulleys. He has also tested the solenoids, then functioned correctly. i believe he has also using his User tool checked VVT operation, cycled correctly.
where do we start looking next, the car is killing moral haha
any comments or ideas would be appreciated.
Brooke J on May 15, 2019:
Hi, I have a 2006 Nissan Altima SER. Its a 6-speed manual transmission. I've religiously taken my car in for oil changes and other tunes up, but lately it feels like I've been having to add oil a little more frequently. I've been hear a knocking sound from my engine. I believed it was due to low oil levels, so I added more. Still knocking. Especially when I get into gears. I wasn't told after my previous oil changes if I have a leak.
But just today, some white smoke was coming from my exhaust pipes. Should I take it back and see? Am I due for another oil change already?
Eddie Carrara (author) from New Hampshire on May 13, 2019:
If all of the Hyundai's make that noise, have them compare it to another vehicle similar to yours, a side by side comparison would give you the answers you're looking for.
Keith on May 08, 2019:
I have the same issue as Jpr1964. Same motor but in a 2013, Elantra with 103k miles. Using an automotive stethoscope, I've determined that the noise is most pronounced on the top, passenger side of the motor. The side with the timing chain. Changed the oil and strained it to see if there were any metal filings.Thankfully only one tiny speck. No change in sound after the oil change.The ticking noise is most like the first one in the above video. It's a sharp ticking noise that gets louder upon acceleration. What would be my next step to diagnose the issue? Pull the valve cover and check the cam lopes or check the chain tensioner? Thank You!
Jpr1964 on May 08, 2019:
Just bought 2014 Hyundia Elantra 1.8 l dohc used from a dealer w a 3 year 30k warranty. First day i had it home when i started it i was making a loud knocking and ticking sound. Brought it back to dealer, they told me that its supposed to have a OEM oil filter and 5w 30 synthetic oil. Knocking sound was gone, and ticking was noticeably less. Sounded fine for a week then ticking sound got louder. Brought it back again and they told me the ticking sound was the fuel injectors and they all did that. Noise used to go away after 5 minutes but stays even when up to running temperature. The ticking or tapping sound is coming from the passenger side of the engine. If it was the fuel injectors wouldn't I hear it across the front part of the engine where the fuel injectors are located? Its driving me nuts and i want it fixed but i they don't want to fix it

I can't really see where the oil leak is coming from in the one picture. Have you checked your oil level? Low oil is not usually the culprit of a no start engine unless you ran it dry and it seized. Does the engine turn over?

If the camshaft is damaged you can drive for a while and it will never get better but if it gets worse you'll need to replace the camshaft and rocker arm.
Mezo on March 30, 2019:
What i meant by what to do next is, should I replace the camshaft and the damaged tappet or there is a chance they can break in?
Especially if the scratched or worn out area in the cam lobe and tappet is in one border where the gravel rested in
The oil levels is not decreasing.only knockeing and rattleing when accelerating.
Any suggestions would helo alot.
Mezo on March 30, 2019:
I had a cam lobe and its adjacent tappet of my 4b11 lancer x 's engine bruised dut to a gravel went down with the oil in the valve case when the mech was changing oil.the cars started to produce sound when accelerating.opened the case found the wear on the only one cam lobe and tappet extracted the gravel.what should i do next?

See if you have spark in that cylinder. If there is no spark, you'll need to find out why. If you have coil overs, you may have a dead coil.

I have a 350Z 2005 enthusiast 185k
I baby my car. Synthetic / 4-5000 miles.
Maybe unrelated but I ran over big rig retread the other day, it ripped the lower bumper off n the under engine guard. That’s all fixed BUT now I’m hearing nasty fast tapping, I saw slight smoke (like cigarette smoke) when I lifted the hood. Oil level is good no oil under car Any thoughts. I’m at the mercy of the shop st Nissan. Thanks.

My 2001 Toyota camry v4 has suddenly started to make a ticking/knocking sound from the top of the engine. The oil level is fine and there isn't a leak or oil mix. i am guessing the top cylinder.
Anything that you could tel me would be a great help.

Not sure what the year make and model are but it could be a lot of things making that kind of noise; like the camshaft, piston, timing belt or chain tensioner, etc...

I have a kia sorento 2003 model and it is a new overhaul but after overhaul there is knocking sound, new changed oil also... what is the cause of knocking sound? I already put two bottle of oil treatment...
Eddie Carrara (author) from New Hampshire on January 02, 2019:
Hello Mr Murphy,
That type of ticking noise was caused by a worn camshaft lobe. If your noise is intermittent, most likely it not a camshaft lobe issue and more like an external engine belt tensioner, timing chain tensioner, or something else external.

Good day, engine started making this ticking or clicking noise if you will. The noise sounds like the honda at 0:55 in the youtube video in your article. Thought it was low oil or maybe leak, but i had put oil in it a few weeks prior. Took it to a dealership and mechanic said there were no leaks and that it was the solenoid valve and replaced it. I didnt hear the noise upon picking my car up, but i heard it again when i got to my house. Now sometimes it doesn't make the noise and sometimes it sounds like it did before i brought it in. When i hear the noise it does get louder and faster as the rpm's increase. It's a 2013 chevy cruze with 34k miles. ( in know it's not that many miles for the year). Thanks in advance.

I have a noise coming from my engine I've been told it's probably either the lifters or it's spun a rod. I have a 2013 Yukon XL 5.3 Vortec. Is there anywhere I can send you a short video so I can get a quick opinion
Eddie Carrara (author) from New Hampshire on November 26, 2018:
I recommend checking the starter wires to see if any are burnt.

brendan on November 21, 2018:
hey I just got my truck on the road having a ton of issues its seems all little. truck was fine. got it back and none stop problems timing belt went up. no damage but after that cost me 800 dollars to fixing got it back the terminate housing had a leaking took it back they fixed that free cause they damaged it I was just driving to work and my engine developed a knock and now has coolant and oil leaking I get to work. and discover they didn't attach a clap to the bottom coolant hose could this result in this kind of damage engine is now knocking and leaking oil which wasn't happening before this truck was in running order and bought it only a few mouths ago ran it for 30 days fine no problems but as soon as I take it to that shop problems after problems
Eddie Carrara (author) from New Hampshire on October 29, 2018:
I'm not sure what you're hearing but I don't think its an issue. Most engine issue are heard at idle or when accelerating under a load. I recommend checking the oil level just to be sure it's not low.

I have that ticking noise in ‘15 Civic on highway when at high speed..let of pedal and it quiets down. Noise developed 2200 miles after my last oil change (valvoline maxlife 0w20). First time ever with issue!!! I thought it was sounding like valve lifters.
Eddie Carrara (author) from New Hampshire on October 02, 2018:
Can you take a video of the noise and post it to YouTube then send me the link?

I am having weird tiking noise when riding but not when idling also as soon as i pushed clutch pedal the noise goes away.I already changed cam chain.
Eddie Carrara (author) from New Hampshire on September 19, 2018:
I highly recommend you bring it back to the mechanic and take them for a test drive to point out the noise, they may need to make an adjustment or inspect their workmanship. Let me know what happens, thanks.
OtobongJackson on September 18, 2018:
Good morning please my car is a Toyota Camry 2004 I have a slight knocking sound when I start my engine every morning after few minutes it stop the sound, I then took the car to a mechanic and he me he have to changed the chain , adjuster and rail and he did after fix them the sound stoped, but while test running the car it starts the knocking sound more than before so please what should I do?
Eddie Carrara (author) from New Hampshire on April 22, 2018:
You'll need to locate the leak with a flashlight. The mechanic could have damaged the seal during installation as well. If you brought the vehicle in to have the leak fixed and it is still leaking then I recommend bringing it back to have them double check their work, especially if they stated your leaks were fixed. Let me know what they find, thanks.
Charlena on April 20, 2018:
I have a toyota camry. Ive had my cam shaft and crank shaft seals replaced a new timing belt and fuel pump. My car still is dripping oil out. Any idea what it could be.
Eddie Carrara (author) from New Hampshire on April 17, 2018:
The mechanic should have seen this problem when they replaced the lifter and it would have cost a lot less money. Does the mechanic guaranty the noise will be gone with a new camshaft? Are they going to charge you labor to install a new cam because it should have been replaced the first time the cylinder head was apart. Let me know, thanks.
Makisha on April 17, 2018:
Hi, I have a Toyota Rush 2007. My engine makes the noise heard at 0.55 seconds in the video. My mechanic suggested changing the Lifters, which i did, but the problem still exists. He is now suggesting changing the cam shaft. Is that correct? I have spent alot of money trying to diagnose the problem
Eddie Carrara (author) from New Hampshire on March 26, 2018:
If your engine has a knocking noise like the video, it may be time for a new engine, but not for 10k. You should be able to buy a salvage yard engine with low mileage and have it installed for about 5k.
I recommend getting a second opinion by someone reputable. Let me know what happens, and if you have more questions, I'll be right here :)
FYI, your gender has nothing to do with knowledge, a lot of guys don't know much about cars and get ripped off too, that's why I answer peoples questions. I don't know everything, but enough to be dangerous and I can steer you in the right direction :)

I have the exact same sound in my V8 Holden VE SS Manual took it to the mechanic who said I need a whole new engine only had the car 6months an can't afford a $10,000 New engine. Do I need it or is it something else. Everything is worked. With Calais coolair take to the Calais Exhaust.. everyone says cause I am a girl an don't know the real problem he is ripping me off.
