TOURAN 2.0TDI - BKD

Hi All

Need help. My VW has a new cylinder head with new rockers and new injectors. Still waiting on new wire loom for injectors. After I fit everything(with old loom), when cranking, without intake pipe on turbo, there is a stream of oil coming out turbo inlet side. I removed turbo and not really any play on impeller shaft, everything looks good. Oil feed to block is open.

With turbo outside vehicle, I tried to force oil through oil inlet on turbo and oil don't come through inlet when I do that, but.. I need to force the oil through with compressed air before it comes out on oil outlet side. Is there suppose to be so much oil pressure inside turbo core before the oil returns to the sump? Other than that I can't fault the turbo. Its there is too much oil pressure inside the turbo and now it pushes past the seal on intake side. I noticed on dipstick the oil is about 3mm over full line, can this be the cause?

Any advise would be appreciated.

Have you checked the return line for a blockage. The pressure to the turbo is the same as what is supplied to the rest of the block.

Blockage for sure
