Reply With QuoteIt could really be anything and it might be fixable too. I fixed a back hoe for a friend a couple of years ago, the motor was totally siezed. It turned out (we are still not sure why) it had spun a couple of big ends fortunately not damaging the crank just coating it in white metal. I managed to clean it up and the conrod and fit new big ends, I also checked the oil galleries and installed an oil pressure gauge too. It has run great ever since, so maybe the new owners will be lucky.
I would never try to turn over a siezed motor though with a breaker bar, if it wont move, I open it and dont force anything.
