I have a 2005 Korando 2.9 TD. I'm currently hearing a sound like a burst of air intermittently once the engine is at running temperature. Could it be the EGR valve fail? The engine starts and appears to run okay at the moment.

Answer

It is possible there's some excessive exhaust noise you're hearing. The EGR valve is a possibility: a leak at the manifold to valve gasket, valve to tube gasket, even the EGR tube to manifold tube nut -- depending on your particular model. Also check for a possible damaged exhaust manifold, manifold to cylinder head leak, or exhaust flex joint problem (spring, seal). And check the turbo for leaks if necessary.
