turbo oil pressure

[bass_direct]

Have you made any modifications to the oil breather setup on the rocker cover by any chance?

I have no pipes on them yet

I had a similar problem and it turned out that I'd forgot to install a non return valve on the breather pipe from the inlet manifold to the rocker cover, this then meant that the boost was getting into the engine.

This lead to oil getting past the seals on the turbo due to high pressure and into the pipe work leading to the inlet manifold, check to see if the inlet is oily, if so and you have a return valve fitted it could be the turbo seals.

I don't have the boost pipes on the turbo yet because I don't have them.

I've connected an oil gauge into the turbo line and when cold at idle is 50 psi and warm it's 16 psi.revving when warm it goes up 10 psi per 1000 revs.

I think I've solve it.oil return line is to small.ive took the turbo off and fitted a bigger piped flange and have a milk jug screwed into the oil filler hole in the rocker cover then cut a hole in the side of the canister and slide the return pipe in to the canister, started engine and let it run and no oil is coming out of the turbo.had it started also with the smaller pipe and oil is coming out from behind the turbine wheel right away.
