Question about Mitsubishi Passenger
I have had the rocker cover gaskets replaced 3 times in the last 2 years. The most recent when I had the motor rebuilt professionally by a reputable mechanical shop. In the past it has leaked both sides but this time after 4 months its back to its normal tricks on my garage floor. Definitely coming from the passenger side rocker cover. Is this an inherant Mitsubishi problem or is there a simple solution. Gaskets used have not been orig in the past.
Had same problem it turned out to be seal at back of head at rear of camshaft replaced those seals 2years ago no more leaks

The gaskets may not be at fault; the first time the valve cover was removed it was probably damaged by an impatient mechanic.
Most covers are sheet metal and the gaskets have an ugly tendency to get sticky over time making removal very difficult.
An inexperienced or sloppy mechanic can easy damage the edge of the cover causing a permanent distortion that a gasket replacement cannot correct.
I hope you have correctly identified the source of the leak since a warped cylinder head can also cause oil loss but that would be from the junction of the cylinder and block.
That would be much more expensive to correct than replacing a damaged valve cover.

Use a film of gasket sealant on both sides of the new gasket when you replace it. When installing the cover, make sure there isn't any wiring or anything that could get caught under it.
