Thanks Dave, I've now actually begun the adjustment. The engine is in surprising ly great shape inside. Clean,- actually shiney- no signs of sludge or overheating, no signs of valve stem or cam wear. (But then this car only has 20K on it!) As you said, I did only find two valves (on the one bank I have completed so far) that needed adjustment - but WOW, what a difference! The rocker noise has diminished a lot. I still have one bank to go. I decided to just adjust (or check) each valve at it's low spot (or exactly opposite the peak, and only follow the manual with regard to the clearance measurement. As a sanity check, I took a compression reading of each cylinder before I started, and am comparing that reading - to one taken after I finish. - This will at least tell me that I have not "over adjusted". (this, combined with accurately measured clearances). So far, I'm pleased with my results. And I'm hard to please! :-) Eric Dunedin, FL --- In dmcnews@xxxx, "jtrealtywebspannet" <jtrealty@xxxx> wrote: > I just completed a tune-up on a "D" and I found after 30,000 only 3 > valves needed adjustment and it was very minor.
