i have no idea when or how this started but i'l give you a quick run-down.
the spark plug area of the 4g93p rocker cover is seeping oil. most probably from the 2nd, 3rd and 4th spark plug bolts. no crack is visible. oil starts to appear in that contained area after driving and shutting off the engine (it seems that way).
so far, here's what i've done to try and rectify the problem:
1. thought bolt threads have worn out, so changed all 4 spark plug bolts. also, these bolts were torqued according to the manual in case some of you might have thought i'd over torqued them.
2. thought gaskets were gone. so i changed the spark plug area gaskets as well as the rocker cover one while i was at it.
3. thought it was time to service, so i changed oil to my usual Q8 semi synthetic along with original proton oil filter.
4. figured it might be the PCV valve (Positive Crankcase Ventilation valve) since it was kinda stuck and the hose was cracked at both ends so i changed both items.
none of these solved the problem!!!
could fouled spark plugs cause this to happen?
somebody pls help.
