Coolant leak, '01 A6 4.2

[Mark Rosenkrantz]

Sounds like the so-called "crack pipe" on VW VR6 engines.  Common failure as the plastic ages and becomes brittle.

There's a guy goes by the name Fusilar or something like that on Audiworld
and Quattroworld who has made an aluminum replacement for a plastic pipe
Audi installed in the coolant supply between the block and the oil cooler
on the passenger side of 4.2 V8s.  His pipe features double Orings on each
end.  Audi's plastic has a single O-ring on each end.  The pipe is about
2.5-3 inches long.  Failure of the plastic at mileages upward of 100k is
being reported.  I have one of his pipes in the glovebox of our S8.

Anybody here with any experience on these "new" cars?  We have a car in 
the shop with a pretty respectable coolant leak on the right side of the 
engine, and we're looking for some BTDTs.

Thanks, John
