ive got a bit of a problem with a newly recond turbo on an f7p.on start up it runs fine but after about 30 seconds it fills the place with smoke.oil pressure in the car is around 4 bar.could i have to much oil pressure for the turbo? the dump pipe is going into the bottom of the block at the back of the starter.

If the turbo is new, that shouldn't be the problem. I had a similar problem when my turbo return pipe was getting blocked up.

would the sump internal slash guards cause a restriction ?

as above, ensure the drain is free flowing and make sure you've not overfilled the engine with oil.

I've disconnected the drain and started the engine,there is oil flowing from the drain but I thought it would have been more than what there is.what sort of flow should the return have say per minute?

Depends if you have an oil restrictor for the turbo, but generally it doesn't flow that much, just a steady stream.

The factor sump plastics shouldn't affect it, where is your return located? Any pictures?

return is in the same place as yours.

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.

What's the spec of your build?
