video - good idea. will-do.
had another thought: one of the crank bearings self-destructed and now resides in the oil pan. so, low rpms, little stress on crank, it flexes without that bearing but not enough to impact the block. at 3000 rpm, it's flopping around, sometimes hitting, sometimes not. 3500, hits solidly ever time. higher rpms, seems to go away a little, maybe because it's hitting the block sooner.
if that were the case, I'd need that part of the crank ground, and a new set of crank bearings. can this be done with the motor in the car? in terms of hours, easier to pull the motor? |
