not sure until the head is pulled...but I think the knocking was maybe the piston just tapping the head after the bearing moved??

thats what happened last time

with the crank being brand new and all its "surface hardness" being fresh...and the engine ran for no more than 45 minutes. I think thats what saved the crank

the old crank was all chewed up...but it had been ground and I think most of the hardness ground out of it...if that makes sense
