[A8] breather hose

That's the same hose I wrote about a few weeks ago; as mentioned, I used
3/4" standard fuel line.  There are actually two big ones back there (the
one on the right is even harder to get at), and a third smaller one that
wraps up and over the motor.  Someone else mentioned removing the intake
manifold to get at them, which certainly would make a HUGE difference in
access, though I don't know how easy it is to get the IM back in place.

> I finally have some time to devote to my 99 A8. I bought two oil filters
since they were $10.00 a piece, synthetic oil and changed the oil even
though it was clean (didn't want to trust what was in there). I also wanted
to check a very small leak and smell so, up the ramp she went. It looked
like the oil was coming from some unreacheable place way above the rear of
the motor. I took the engine covers off and behind the valve cover there is
a breather hose that goes into the engine itself or what appears to be the
crankcase. This hose was absolutely deteriorated. I called the stealership
and they wanted $126.00 for a hose literally 10 inches long (ha,who could be
so lucky?). I looked in my parts bin/garbage bin and found a similar shaped
hose, in excellent rubbery shape, from my 76' 280C emissions crap that I
took out. I cut it and after much PITA slapped it on. I also bought a cabin
air filter. Can somebody tell me where it goes? I ordered the manual but it
is backorderd from
