80 Quattro Turbo exhaust clearance

[Robert Mangas]

   Sorry, but my turbo manifold exhaust leak experience is limited to my 
miata.   Here's a thought though- an easy way to track a boost leak is to 
pressurize the intake.  In the course of my work I sometimes have to inspect 
exhaust systems for leaks, and that's exactly how we do it.  Most of the 
labs will have a fitting that will allow fixing a regulator to the tailpipe 
and then we hook it up to the shop air.  3psi will do it.
