blowby
So had oil coming out of the turbo exhaust and after a compression test found 3 and 4 are at 50psi. My oil feed runs from the cam feed on drivers side behind the head. Haven't pulled the motor yet but seeing if this location is to why this happened or if it is a result of 12 years of nitrous. Would think that all the oiling comes from the crank feed but asking the professionals. Thanks

That's nice to know. Haven't got to drive the car much but did take it to one autocross so when I pull it I'm going to check the cam for wear to make sure it was getting enough oil. There was definitely enough pressure out if it; started with a -04 line and when the turbo started leaking I changed to a -03 and put a new turbo on which leaked. That's when I noticed how much pressure was coming from my catch can. After finding the compression numbers came to the conclusion there was enough crank case pressure it was pushing the oil coming from the return back into the turbo

I saw that the port was supposedly only that year when I was researching so was surprised when my 01 had it. Everything sounded good when it ran just didn't get to run too long. A hard day at the autocross lost about half a quart. Thought maybe the bushings being a used turbo so just went for it and bought a new one. After 2 starts it was toast. Seems like quite a bit of endplay (around .010" to .015") but basically the whole blowby problem got worst in a matter of 5 starts that's when I did the compression test
