I don't think the lifter cause it either that's what I was trying to say about a possible burnt valve. I was thinking a burnt exhaust valve that stuck closed may have cause the lifter to collapse. You think that could be the root cause....a burnt valve? It would also explain the lost compression?


So you're saying pull the rockers and retest compression?

Carbon build up on the valve stem.... Decarb time.

OR IF the valve already contacted the piston it may be bent.

Well, I got her fire up last night. Ran it with valve covers off and got the valves dialed in. Lifters pumped up good and had good pressure.

The only thing I can attribute it to at this point is the HEAVY carbon buildup on the valve stems that must have caused those couple to stick and crush the lifters. I went through both heads and reground them. Its purring like a kitten now. it hasnt been that quiet in some time. The miss is definately gone and its smooth as silk.

I got a few loose ends to button up so I can drive it a couple days. I dont trust it to go 100 miles to hunt this weekend so probably going to ride with my buddy till I can get some more around town miles on it first.
