Hey hetzle -
i've seen oil build up from the front mount intercooler as well
both n54 and n55, it's common. the build up is most likely from the
turbo - maybe someone can chime in with details.
btw, sorry to hear bout ur botch'd tune install.
read ur post.

Very interested in the intake manifold pics after 50k miles, the n55 is supposed to be a bit better on that subject (supposed better crankcase ventilation system).
Diff check - it made a big difference..
the Vishnu CP, with it's silicone hose to the T-body (design)
is a guaranteed seal - only way air will seap through
is if it pops off or u got a leak somewhere else.
I've been wanting to check out the valves
- soon enough
i'll post up some pics -
also the n55 valve train - i may have some news and
issues. do you know of any know problems on the boards
from a member?
