spun cam bearings
I just had a brand new engine eat the front three cam bearings and spin the rear two forward out of the block. The engine had less than two hours run time and those were only on the dyno. Everything was all new, but the belt drive or belt drive tension seems suspect. It was a Danny Bee belt drive on a SBF with fairly mild (.715-.679 lifts) solid roller in an R302 block. Would too much belt tension have been the probable cause for cam bearing failure in a new engine? Has anyone even HEARD of cam bearings going down in an engine? It's a new one on me.
