Okay, so I posted an issue previously, "Can't figure out this valve tick." Well, today I did. After reading all the responses from people with far more experience than I, I pulled the valve cover and decided to run the engine with the cover off and physically attempt to locate the offending rocker/tappet etc. So I started the engine and behold all "valve tick noise" is 100% gone. I couldn't believe it. So... I looked very carefully and found that the rear oil tube was loose in the holder and was pulsating under certain condition and was hitting the top of the valve cover. I've attached some pictures. The only thing I may do now, is put a new lower grommet on that oil tube. Does anyone know if I can do that from the side engine plates without having to pull the valve cover again since I put it back together. How important is that lower grommet? I imagine it would lesson oil pressure if not tight. Again, this is the rear tube that oils the rockers. No broken valve springs, or bend push rods, rocker shims seem okay. Thanks everyone for the excellent insight and knowledge you shared with me.
