[Vwdiesel] need oil return line for turbo-85 Jetta TD

The part number referenced in an earlier post is available from
www.1stvwparts.com (Auburn, WA VW) for $150ish.  
The lubrication system isn't where I would cut corners.  If you are worried
about it... It's a lot cheaper to replace than the turbo or the engine.
Just my $.02

   SUGGESTION:If there's no holes in it, I'd just clean it up and paint it, 
personally.  Thought my 5Ktd one was toast because the stainless braid area 
was all collapsed and kinked.  Cleaned all the dirt out, wiggled it a 
little and it looked good as a few years old!  :-)

CONCLUSION: Loren's "Painting" and "braided" implied the question of what 
kind of paint and what kind of braiding......and "high-temp epoxy" came to 
mind.  Prepare the surface with a brass Dremel brush, treat the clean bare 
metal with  phosphoric acid etch, and wrap the line with epoxy-pasted fine 
wire window screen , cut into quarter-inch wide strips. This would cure up 
as a laminated tube.   The laminates would have different rates of 
expansion when the turbo heats up, so there is a risk/probability of 
cracking  in the epoxy bond between the various metals. But maybe the 
little islands of bonded material would reinforce the areas of the original 
tube that were weakened by corrosion over the  22 years of use, and prevent 
further corrosion over the ?? years that the Jetta has left.

Sounds like a plan. Gonna try it this morning.

Thanks again for bouncing the ideas around.                    Doyt
