I have been having this oil leak problem. At first I thought it was just the oil return line gaskets, changed those with new crush washers, still leaked.
Got another oil return line(thinking the flex was cracked) and it still leaked.
Upon further inspection it appears to have oil leaking from where the hotside and cold side meet together, and is v-banded together, can a turbo even leak oil from there and does it mean I need a new turbo(14b)?
The turbo has minimal shaft play up and down and no in and out play so it appears to be in good shape shaft play wise.

Does your exhaust smoke? Sounds like you blew a seal

No noticeable smoke from the exhaust...also the tailpipe does not look oily or anything like that, Just an oil leak.

OK well I am porting the OFH since I was seeing 100+ psi at 3k rpm and up. I figured the turbo would be ok since it has the stock 1g oil feed from the head...
Will see if lowering the oil pres. will stop the turbo from leaking.
