Message: [QUOTE="Derek@Vision Diesel, post: 429806, member: 344"] Got a closer inspection of more of the valves this morning. Seems as though the previous machinist was straight out of high school. 10 out of the 16 valves on the passenger side (which we removed previously) show signs of not sealing correctly. Another thing I thought of. If he took .012-.014 off of the surface of the head, then cut the valve stems, and recessed the valves.... Wouldnt you want to shim the spring to maintain seat pressure? Hell that right there could be the reason for valve/piston contact, couldnt it? The vales hanging open because of lousy seat pressure? Maybe this minimal amount wouldnt affect it enough, but just something that ran through my mind this morning. [/QUOTE]
