'01 XC oil in air ducts, pcv good

Hi,

I changed my ETM this weekend & inspected the PCV system, while the PCV looked good & must have had recent service from the po, the charge air piping was somewhat oily inside.

So the question is how much oil is normal inside the ducts & what could be it's source other than pcv, how prone are the turbos to leak oil into the piping?

Thx, Ben

Seems likely that the seal in the turbo is leaking

I would say an oil film in the induction pipe would be normal. If you have liquid oil in the tubes, turbo seal leak or heavy PCV blowby indicated.

Thx abscate, I would've expected something I'd call traces but your expression "oil film" describes it quite well, I guess all is good then!
