After a major engine rebuild (mostly done by professional machine shop), the engine started and ran beautifully for about 100 miles.
Suddenly things went south - diagnosis.. a bent pushrod on cylinder #2 exhaust valve.
Most obvious cause would be a stuck valve but that does not appear to be the problem. No other cause that I can think of??
Installed a new pushrod (from Moss) and, again, the engine is running great, about 100 miles so far. I'm keeping my fingers crossed, hoping it was a freak event.
However, would very much appreciate any input.
The ignition timing was quite retarded (my fault) and an old timer at a local repair shop mentioned he vaguely remembers this sometimes causing damage to a pushrod on older engines.
Again, any input very welcome.
Thanks
