STi 8 Intercooler
I've just bought a 2nd hand STi 8 Intercooler, there is quite a lot of oily residue in the pipe that leads from the turbo and in the Y pipe. I take it this is not normal?

Quite normal, the system re-circulates oil vapour into the intake to save the planet... and cause detonation in the engine ! A good clean and she'll be fine.

None I'm aware of, I got one a week ago, but still need some hose, as my Samco inlet has no breathers, to avoid this exact problem.

Oil vapours recirc'd back into the intake system can lower the fuel's octane rating... So venting to a catch tank instead is very much a good thing
.DOH! Just seen dunx's first post
. Sorry
