OK, My engine is good, rings and all no problems there.
Oil is backing up thru the turbo, why I don't know.
The guy at Innovative Turbo Systems told me that the oil return line should be at lest 1/2" a # 10 I think. My line is NOT 1/2" I/D. I have 1/2" O/D braided steel return line which is just over 1/4" I/D and a 1/4" O/D feed line that has an I/D about half the return size.
I bought this ASR kit used, I had the turbo rebuilt and the turbine and shaft replaced. I talked to the guy who had it be and he didn't have a problem with oil going thru the turbo (he's a good guy and wouldn't misled me) he toasted his engine, in fact I pulled one of his rod bolts out of the turbo.
As for the oil return line routing, I have the oil pan tapped with the oil tube draining right on to the upper baffle, and the return line sloped at a 45`in to the oil tube tap.
The more I think about it, I believe it must be the return line size.
It's just an oil cooled turbo no water.
