My Magnette did something similar. It started to clatter going up a hill at
high RPM, then it grenaded. It blew a fist size hole in the side of the
block and noisily expired. The cause? Probably a failed rod bolt but there
was nothing left to make a determination. You should be glad you had it
carried. I'd drop the pan and check out the bearings.
