90's EGR Systems
-
Anybody know anything about 90's vacuum controlled EGR systems? I've got one of those goofy little Japanese import trucks, and finding info about how it's supposed to work is a nightmare.
There's a pretty good vacuum leak out of the top of the vacuum amplifier/signal doodad. Kinda UFO shaped deal between the vacuum advance, intake manifold and the canister.
Any ideas on diagnosis, or ways I can figure out what's doing what would be helpful.

Car Wizard uses a smoke machine to find vacuum leaks. As in, injecting smoke into the system so you can see where it comes out. I thought that was pretty clever.
