Bobcat 600, got hot

[Worn out bobcat]

I backed into a snowbank and plugged the air intake. Of course i didnt have a clue untill it started making some noises. Drove it the rest of the way down the driveway and it quit. I imagine it got real hot. Where do i start looking for damage? Spun bearing maybe? Anybody?

Too much heat can be detrimental to both the engine and the hydraulic system. Try turning the engine with a wrench on a crankshaft puley... disconnect the belt if it does not spin and try again ...Check your motor oil, is it normal or looks like milk?

Oil is good. It turns over, it started when i bumped the ignition, but definately some kind of internal damage. I shut it off right away not wanting to do more damage. Im going out now to pull the heads off and inspect cylinders and pistons, what i can see anyways. I know its wounded but not locked up.

When the engine overheats, the first thing that happens is that the pistons bob at the cylinders because of the temperature expansion. If the problem is caught in time, it can get away without repair. Otherwise there are deformed pistons, stuck piston ring and badly damaged cylinders, cracket head and so on. Once the engine is rotating now / after cooling / there may be a chance of a minor breakdown.

Thank you sir.

Thank you sir.

On the shrouding of each cylinder bank is a round bi-metallic disc switch, like that inside a coffee maker, that is supposed to shut down the ignition in an overheat condition. That is probably what tripped and shut you down; when they cool off they reset.
What makes you think there is internal damage?
