I suspect a rocker arm shaft broke on my motor leading to a sudden and massive valve tappet clearance on the last rocker\valve. Thus, pounding the hell out of one of my roller lifters.

I'm going back with flat tappet solids, but I could see running hydraulic if performance wasn't the BIG issue. And on my new build it is not.

Very lucky I didn't grenade that high dollar side oiler block!
