Oil Leakage on a Honda V6 Engine

The article, via video, will show you how to address and fix oil leakage from hardened and dry-rotted valve cover gaskets on Honda V6 engines.

Over time, the valve cover gaskets on Honda's V6 engine lose their sealing properties. As a result, engine oil will seep and leak around the perimeter of the gaskets. These gaskets will harden and become brittle, almost like plastic; bending an old gasket like this that's been removed will make it break. Sometimes the gaskets get so hard they cannot be removed from the valve cover gasket grooves unless pried and chiseled out.

The valve cover applies pressure on to the gasket with valve cover bolts cushioned with thick rubber washers or bushings. These bushings also lose their elasticity and harden, so they need to be replaced along with the valve cover gasket.

Although gaskets can be purchased for each cylinder head (two cylinder heads for V6 engines), I recommend you purchase a kit that comes with a pair of replacement gaskets with new cover bolt washers, and in some kits, the spark plug tube seals.

Getting working clearance to these gaskets requires the removal of the engine's intake plenum. This requires the removal of the air hose, electrical connectors, vacuum lines, and some coolant hoses. The ignition coil packs can then be removed before unbolting the valve cover.
