Default Comprehensive Vacuum Leak Testing Guide?

Hi guys,

Do we have one complete guide to hunting the vacuum leaks? I know there is one for HVAC, but how about tracing the rest of them?

Thanks!

Should just have a smoke test done. I originally thought I got all the leaks, but the smoke tester proved otherwise. Once fixed the car was so much happier.

Is this something that can be done on your own or would I need to take my car to a shop. Honestly, I never done any vacuum testing before, that's why I hoped there is a comprehensive dummy guide somewhere...

I never did either until i owned a 928 and had the great benefit of fine technical instruction from these people.

Very useful. Anybody got illustrations. There's a lot of stuff under that hood.
