Michael, the M103 is an "interference" type motor. Having said that, in Larry's case, his error sounded like a tooth in the retarded direction which would lead to late opening valves and reduced performance and increased distance between the valves and piston crowns. An error in the other direction can be more of a problem. If a valve is full open before the piston arrives at TDC, there will be "interference" (crunch). Larry has had a great passle of good luck with this casualty. I'm glad the "babe" is back to health... Good going Larry!!
