[QUOTE="AfricanSnowOwl, post: 16494722, member: 168923"] Got it all back together today and fired it up. Let it warm up and checked for leaks, then set timing. No leaks! but it is still the same rough and rich idle. The vacuum gauge was low, 14", with a rapid vibration that steadies out at higher rpm. According to a bunch of different sites, that indicates worn valve guides? Is a bad idle a symptom of that? Can you still have messed up valves or valve guides and pass a compression test on all cylinders? There is only a little bit of grayish smoke at idle sometimes which I assumed was due to the rich condition. It doesn't appear to consume oil, but I wouldn't really know either. I've driven this car maybe 5 miles total since I brought it home. [/QUOTE]
