Oil where it shouldn't be
Howdy all! Recently bought a '94 2.0 16v coupe, was changing the spark plugs and noticed that the plugs from cylinders 2 and 3 were totally drenched in oil when I pulled them out, there was some oil on the other two plugs but no where near as much as the middle two.
I've also noticed a small oil leak coming from above the oil filter, oil only flows out here when the engine is running, and there is also a fair bit of oil around and below the rocker gasket.
Any ideas what could be causing this? I've been told it could be the oil rings on pistons 2 and 3 not scraping oil from the cylinder wall on the downstroke, which would mean they need replacing... or could this be a rocker gasket failure?
Any more theories or solutions would be much appreciated.
