[QUOTE="garyahouse, post: 1063954, member: 20946"] +1 Wfooshee. Like I said, you're rolling the dice doin' a repair. That head of that valve head both took and caused some major hits and transferred some nasty forces to that con rod and the crank. The time, $, and risk is huge for a top notch FJR mechanic, let alone a good man who doesn't seem to know WHY his engine jumped timing after he worked on it. We're not trying to be critical here, most of are capable of doing exactly what you did, and maybe even having the same results. However, with all the risk and expense involved, what a shame to get it all back together only to find that the crank is jacked... and maybe not til many miles down the road. If ya must wrench, maybe consider another engine? At least you'll have plenty of good engine parts to keep for a rainy day?? Gary [/QUOTE]
