Since all of our 1980's diesels (specifically the W123) rely heavily on the vacuum system, why don't we put together a FAQ on a step by step way to find the problem?

I have a digital camera. I'm having a vacuum problem and I hate to spend $$ at my indie mechanic if I don't have to.

I'm sure if we put our heads together, we can come up with a great FAQ.
