Surprised it damaged the head gasket though. I can see the valves not liking it, with the inlet valve having to cope with hot exhaust, and the oil pump running backwards isn't going to send oil around the engine, but would be interested to know why the gasket failed.
Can't say why it damaged the head gasket or if it damaged the head gasket, it didn't run for many seconds like that, it didn't overheat, and restarted normally, but had blown oil out and it had oil in the radiator and water in the sump. May just have been a weak spot?
He did say that it tried to rev when he pushed in the clutch, I don't know if that engine is regulated by a butterfly in the air intake, (would have no regulation in reverse), or by the control of the pump
it wasn't sucking oil because it shut off on the engine stop...(It's a Perkins engine, the tractor was made in 1960)
Thanks,
