Why did the pushrod bend? Uh, ya know, they don't get soft in oil and just squish up. Something bound up, the pushrod was the weak link and it bent. Valve guides too tight? Retainer to guide clearance? Piston to valve clearance? Did we over rev this baby? Did driving it around with the low oil pressure damage something else? 'Cause, "then it got worse untill it wouldn't run hardly at all..." Did excess fuel wash the oil off the rings and score the cylinderwalls?

Cut the oil filter open and check for metal in the element.

I think tearing this completely down and checking everything might be in order, bearings, clearances, gaps, cam timing, pushrod length, rockers and shafts as suggested above, spring installed height and blah, blah, blah.............or not.

AGREE^^, at least pull the pan and check some bearings. I didn`t get a pushrod right on a cam change, it hammered on start up, I let it idle up to 190 degrees and shut it off. The pushrod did`nt fail, or the rocker, and a lifter didn`t come out all is good now. (They both came from Hughs engines, good stuff!)

Old thread revived from 8 years ago. I wonder what happened to the stroker?
