[Vwdiesel] Signs of PD worn cam syndrome?

[James Hansen]

Usually a turbo seal announces it's failure as dumping major quantities of
oil.  Not a "some oil in the intercooler" kind of deal  If it was being
driven, think either engine failure due to oil sloshing out of the
intercooler and killing a rod, or enormous volumes of smoke spectacularly
exiting the tailpipe.  Significant blowby will accululate oil in the
intercooler quite quickly too from the soot manufactory (crankcase vent +
\EGR), but the seal in the turbo usually fails spectacularly, and lots of
oil leaves the turbo quickly.

I'm not sure how it was diagnosed, but the shop is a VW specialty shop with
an ex-VW mechanic. I've switched gears a bit, and am test driving two Audi
A4Q's tomorrow - an '01 V6 sedan, and a '99 1.8T wagon. Not sure that I can
really go back to gas yet, after 20 years of diesels, but the quattro would
be nice in the winter around here.
