SR20 problem...Oil EVERYWHERE

[Ian]

Symptoms:
-oil on spark plugs
-oil in intake tract (hot pipe, cold pipe, intercooler, intake manifold)
-oil in all vacuum lines
-car smokes fairly badly, only under heavy throttle

Information:
-stock catch can is removed
-from the valve cover, tube still goes to block and still goes to intake pipe
-motor ran otherwise very strong except for smoke
-I believe the compression is good but the plugs have fouled from excess amounts of oil which is why it stopped running well by the end of the drift event


any help here? I'm hoping a catch can and some seafoam will remedy this problem

turbo seals went kaboom is my guess.

oh forgot to say that...


turbo is in GOOD shape! no noises etc...boosts very strong

my DSM had all the same symptoms, the only logical reasoning would say that your seals are steppin out, if your compressor side moves in and out fairly easy, and the oil is where you described, id check on replacing the urbo. other than that, if the catch can is the issue than your boosting the crankcase if its not ventilated and that is also a cause of a blown turbo. i had to learn the hard way on my brand new 20g :-/

now after re reading your thread, it could be blow-by, coming up out of the valve cover and recircing into your intake tract, compression can remain very strong with motors that suffer from blowby, because the oil acts a constant seal onder pressure testing, your compression may be slightly skewed from cylinder to cylinder however, try ventilating the block in a better manner, and check to seee if your dipstick pops out between driving sessions. otherwise have a buddy sit in your car and rev it to build low boost, see if oil drips up and out of the dipstick hole, if thats the case you are most deffinetly boosting the crank case, but if its only a small amount of oil coming up and out, it shouldnt be too much to worry about as far as solving your problem/

I'm pretty sure it's blowby coming from the VC into the intake (stock black box thingy is removed) and hose goes directly to block, on other side goes directly to intake


going to get a catch can and see if it helps after seafoaming the engine
