So I was in they city just crusing along and I get on it a little to only realize its not reving past 3500 and its not going anywere either. Even wen I full throttled it. Next thing I know. There's a whole in the crankshaft caseing. So I swap another motor in starts right up but stops making power at 3500 and stops reving at 4300. So I try driving it at low rpms to get it home 25 miles later a bigger whole is in the crank shaft caseing near the alternater and the connecting rod and brace were sitting right infront of the radiater. So u know the mottor is a f22b1. Yes the motors had oil yes they were low milage. No there were no dents in the oil pan. Can anyone help b4 I blow another motor lol.
