Oil on charge pipe/ Turbo inlet wtf?
 

I just finished full emissions removal and some engine bay tidy-ing.

One of the problem areas was the short hose that goes from the turbo to the charge pipe. It had started to melt and become soaked w/ oil :icon_tdow . It was not factory, just some crap the PO slapped on.

I cleaned everything up, got a new section of hose and rerouted the PCV system as per that S4 TII emissions removal diagram that seems to be floating around.

1 day later I notice oil dripping down the charge pipe and begining to coat my new section of hose! what gives? There is also a small amount of oil sitting in the turbo inlet. There is no shaft play, and zero smoke.

At first I figured the oil was getting in through that metal check valve on the TID but that has been removed and sealed w/ a bolt.

Where is all this oil coming from and how do I make it stop !?! :wallbash:

Turbo is puking oil.

^ what he said

So does that mean its time for a new turbo? oil lines? or what?

I was under the impression (..perhaps a misguided one) that when the oil seals went bad in a turbo, it dumped oil into the exhaust which caused smoking. Is that way off base?

That would be a bad turbine seal, sounds like you have a bad compressor seal.
We frequently rebuild FC turbos if you are looking for a rebuild...

I might have a line on another one locally, I just need to keep her running normal for now.

When its hybrid time, then we'll see...

man could be thta you pressurizing the crankcase which would push oil in the intake tract...

it actually pushes the seal of the turbo out just enough to let oil by but, should only do it suring boost. make sure everything is tight and also try a catch can to relieve sum pressure.
