Waking Up a Turd

Fifth: #7 rod is bent. I found this out whilst trying to measure how far down the pistons sit. One side was down .092 the other side of the same piston down .102
Kindof depends on what you call a side. If you took got those numbers on the wristpin axis then yeah it could be bent.
But if you measured at 90* to the wrist pin axis, then that is just piston rock; average the numbers and you get the proper deck clearance.
There is evidence that all of the exhaust valves hit the pistons at some point. Maybe it had been over reved?
Or jumped the chain.

Nice to see yur back on the case
