Intake Test? (Vacuul leak checker!)

[Robert Deis]

Started using a tool on the "other" car today, and am now anxious to hook
it up to the 5K wagon.  The thing cost $5 to make, and found vacuum
previously unknown vacuum/boost leaks in every single car it's been hooked
up to so far:

Tool is a simple air fitting screwed into a PVC pipe cap, with a robber
coupler that mates the cap to the turbo inlet.  Add air from a REGULATED
SOURCE (no sense blowing anything up with 60psi...) up to the boost
pressure you expect to see, then listen.

All those sssssssshhhing sounds are probably bad. (-:  Identify each one
until you can confirm they belong there or have fixed it, and you're
boost-leak free!

Since I'm barely making 1.1 bar most of the time, I'm certain to find some
nagging problems this way.  Maybe the seals on the throttle plate pivot
pin are shot on my T44, too, though I'll bet that's the smallest of my
problems....

Anybody ever tried this on your Audi?  What "leaks" did you find that
belong there, if any? (ISV, maybe?)
