BBK Issues

Yes it can run with a bad rod bearing, and with every revolution it is causing more damage. Any time you seize a motor you should do a full tear down and inspect everything. The hidden damage can cause even more damage to new parts. Like a pistion slapping a head can crack it, it can stretch the head bolts/rods. It can bend valves and even cause a denotation of the whole top end. (Turn it into a grenade)

OK tore it down again, talked to a mechanic who said it might be an issue with the piston hitting the valves. Took it apart looked at the head and the piston and it looks pike the piston is coming a bit to far out and hitting the head (wear not on valves but the area around it appears to be where the piston is pushing into the head. I was advised to try and put a second head gasket in to increase clearance.
