Finally got around to tracing a minor oil leak on my TDCi Focus. It's coming
from the join between the hose and rigid pipe that connects the air side of
the turbo to the intercooler.
I'm not a mechanic but it seems to me that there should only be air in that
pipe - not oil. I've taken the clips off to inspect inside and there is
*definitely* a film of blank engine oil all over the inside of the hose.
I can only think that an oil seal has packed in on the turbo.
Any ideas very gratefully received!
As far as I know, the crankcase (PCV) is vented upstream of the IC, and
perhaps even upstream of the turbo, so a certain amount of oil in the
intercooler air circuit would be normal. I have a little bit of grime
around that join as well, so it seems the hose clamp isn't perfect for
holding back the pressure. If it is a small amount over a year, I probably
wouldn't worry. If it is a large amount, then this would point more towards
your theory of a ruined oil seal in the turbo itself.

A slight "dampness" of oil residue in the intercooler pipework post turbo is
normal as the oil seals do just weep very slightly. Volvo actually place a
small hole in the bottom of their intercoolers to allow the residue to drain
Keep an eye on it- if its actually *swimming* in oil, or you notice the oil
level dropping then indeed have the PCV system checked first and then the
