Had some issues with cold weather starting which I thought was either tired spark plugs or the MAP sensor, which I've been reading people on here have had issues with.
So I got some new spark plugs and proceeded to swap them out. All of them were tired, but looked in good order except for the one in #4 cylinder (farthest from cambelt).
When I took the coil out of #4 , it was covered in oil, and the spark plug was also covered. So it looks like oil is getting into the plug well from above, rather than from the combustion chamber, and running down the plug thread when the car is standing. The car does use a bit of oil (now I can see why), but not much.
It's the opposite side of the engine, so it's not spillage from putting oil in.
Is this the rocker cover gasket that's faulty and causing the leak and if so, can I change it myself? If it's not a bad rocker cover gasket, what could it be?
Thanks!
