i have a gt2860 on my b18ft and it seems to be burning a bit of oil and i have oil in the turbo inlet and i have a bit of oil staining where the turbo meets the exh mani and downpipe due to lack of gaskets(i have gaskets to go in). I have checked the cylinder comps and there all over 150psi. There is no breather pipework and there is just a cone filter on turbo inlet.
theres next to no play in the comp wheel and it boosts well.I dont get any smoke on idle, i dont know if it smokes when being boosted but it does smell of burning oil.
I dont have oil restrictor in the turbo oil feed as when i did it didnt want to boost, could this be my problem that too much oil is going through the turbo? do i need a restrictor maybe with a bigger hole?
