Hi all,

I'm looking into buying an '93 S4....

I had it checked at a CAA Verification center and the guy told me it
had
a leak on or around the turbo seal....and that there was a litle bit of
oil
in the intake........

I believe it is normal for the turbo bearings to weep a small amount of
oil so
you will always find a little oil in the intake tract. Especially in the
crossover to inter cooler rubber hose where it collects and eventually
damages
the rubber leading to hose failure...

My questions are these......Doesn't the turbo get hot enough to burn
whatever oil gets on it?......how does oil get to it to lubricate
it?....how
is it that he could determine that there is a leak? Is this a sign of a
turbo failure and how much to fix it if it is!......

There is an oil supply directly to the turbo center bearing and a large
oil
return line back to the sump. There are also water supply and return
lines to
the center bearing because it is water cooled...

Could it be that the CAA tech misted the fact that there is a K&N air
filter and that the owner has just cleaned it and thats the oil residue
that
was in the air intake?......How can I be sure?

If the oil was UPSTREAM of the turbo, then it might be from the K&N -- it
certainly would have nothing to do with the turbo. If the oil was
downstream
of the turbo, I don't think the K&N would have anything to do with it...

Aside from that issue, the car really looks in good shape......!

I would greatly apreciate any coments or sugestions on what else to check
on
the car before going ahead with this purchase....

Thanks,
The Rogue
