Here is my problem. When I go for just a normal drive, a lot of pressure accumulated under my valve cover. So much so that my valve cover breather will be launched off the valve cover if I boost at all, and oil shoots past my oil cap. When I take off the oil cap, hot smoke comes out.
So far this is what I have done to find/correct the problem: -Replaced Oil Cap -Valve Cover Gaskets replaced -Replaced PCV Valve (Just tested it, works fine) -Replaced breather filter (Just tested it, works fine) -Did a Compression Test (150 across on 8.0:1 toplines, forgot to open throttle during test, don't know how much that would effect that) -I get 22 in/hg vacuum during deceleration and 19 in/hg at idle -Brand new Evo III 16g -No smoke coming out my tail pipe -My Evo 3 16g can't even get 10 psi untill 5000rpms -I have done boost leaks checks and fixed LOTS of leaks with NO improvement in spool -My car wants to die when I put in the clutch at a stoplight and catches itself at about 500rpms before rising back up to 750rpms
Please help guys, this pressure is REALLY worrying me. It seems that it would almost HAVE to be rings or valve seals, but my spark plugs aren't oil fouled and I have descent compression and healthy vacuum.
