Locked up engine leaves me wondering wtf?
My buddy has an 02 S2k with an F22C. He had a hole in his radiator and let his car overheat. Well once we fixed the radiator it started pouring white smoke out of the tail pipe. He drove it like that for about a week till we could get a head gasket. I changed the head gasket and when we fired the engine up it ran for about 30 sec and the locked up. The #3 rod snapped. I have built/rebuilt 4 F20/22C's Never had a single problem. I triple checked everything and it was all right. There was a small amount of water in that cyl. Obviously he is looking for another engine but I am still on WTF could have caused it.

well, something caused it, rods usually don't snap on their own..
....lack of lubrication+coolant=seizing?
damage was probably done already before you got to replacing the gasket anyways...

did you change the oil prior to starting it up, most likely water in the engine somewhere.

With a blown head gasket and a hole in the radiator, it wouldn't smoke because the cooling system never built pressure, thus never forced coolant into the cylinders. You patched the hole in the radiator and the cooling system started to pressurize as it got hot. But it wasn't hot when he left.
What could the machine shop have done to the head to cause a rod to break?

Isn't it possible that the damage was already done to the rod BEFORE the repair (stress crack, etc) and it finally broke once good compression was pushed again?
