Boost gauge would do fine. If you're getting one of our kits, just get the gauge and mount ahead of time and get credited back when you take the plunge. Plenty of ports on the manifold, might have to T in, depending on whether you have cruise or not.

I can do this test with the same gauge I'd use to measure boost right? If eventually I'd like to have that info available from the cockpit, I could just buy a "boost gauge" and an A-pillar mount and measure vacuum that way ... two birds with one stone right? The alternative being to hit up the local FLAPS and buy a cheapie vacuum gauge ... Is there a port somewhere on the intake manifold to connect to? Any gotchyas or special procedures to follow?

That was not Coop's advice. Coop's advice was to fix the motor before doing anything else. Of course, his goals (start from a known good motor so I don't come around and bug him for service because his turbo install blew up my engine) are not necessarily the same as mine (cheap, fast & reliable - I pick all 3). The suggestion that my motor would probably do fine on low boost for a while came from some folks on another mailing list. I think what I am going to do is this: * seafoam the motor * buy or borrow a compression tester and test once more * find someone with a leakdown gauge that is nearby (this is no offense to Coop, I just don't want to drive all the way to Maple Valley for a leakdown test) and try once more to see if I can confirm the numbers * post the results back to the list one last time * ignore all your advice, turbo my motor, and see how long it goes before it blows ;) I don't quite understand how the numbers are so bad when I'm not using any noticeable amount of oil.

What I didn't get is the advice--which I assume was Coop's--that, "hey you've got a crappy motor--boost it now and rebuild later!" If the motor's not crappy as Bill is pointing out, then it all makes more sense. -Bryan
