If you have a boost leak...you want to do a Boost Leak Test! Not a leak down test.

Heres your leakdown test link. http://www.vfaq.com/mods/wayback/leakdown.htm

Theres a few how to's on making a boost leaker tester on this forum somewhere.

Good link. On my car, to do the boost leak test correctly I have to rotate the crank to close all the valves. Otherwise boost pressure slips right past the throttleplate and leaks past whichever valves happen to be open.

Heres your leakdown test link. Leak Down Test VFAQ

Or here...in this site's tech articles.

And it's also a good idea to have the car warmed up, as with a compression or leak-down test...even though most threads don't mention that.

Yea, I'm a VFAQ.com whore. For some reason I just like it better even though some of the links on the site don't work anymore. The tech articles usually have pictures.
