Rick, I failed to mention that I adjusted the valves while they were cold. I took the stock 273 numbers (.013 and .021) and went .003 less. Do you still think I should loosen them up? Also, I have a PCV valve on the way. Thanks!
Jon, that will be good to try another PCV valve. When i worked at a Gm dealer ( please don't beat me up :violent1:) it was 25 yrs. ago...lol, aftermarket PCV's caused issues alot of the time and replacing them with stock Ac parts cured the problem. To this day i still dont know why? Many were Fram's.
Redfish is correct, you should add a few thou to hot specs when adjusting cold. I know it's a pain, but when you can get around to it i would reajust to a looser setting. jmo.
