Volks--
I've been trying to sleuth out yet another prob on my '84 1.9: erratic idle, compression noise under load, low (er) power on hills, harder starting when hot. I'm toying with the idea that there's a lifter problem, a valve problem, or worse, ie., rings or head gaskets. Now. I went out and got a vacuum guage and compression tester. However, I can't find the correct specs for vacuum readings ANYWHERE in the Bentley or the Haynes manuals. Am I missing something? Nearest I can find, searching the archives, is that 8 in. is too low. Is that right? What's the acceptable range? What else am I looking for in this vacuum test? Just vacuum level? Is there a way to pinpoint problems with it, or does it just tell you "there's a problem?" I want to try backing out the valve adjustment screws to give a .06 lash as suggested by some of the heavyweights here (and in Bentley) but understand it's better to read vacuum and compression before and after. Thanks to all-- Geza |
