Not that ether

Son driving truck, all normal. Died abruptly...no lockup. Cranks over easily, too easily. no, or limited compression. No strangenoises when cranked. No oil, or brown scum in coolant, no water in oil. Before I start wrenching, would like to have an idea what it is. Timing gear stripped? Blown head or head gasket (no exterior sign of leaks? About 200k on motor.

With 5 bent push rods? Pull the cover off of the access to the bolts for the IP gear. look at the bolts that attach the gear to it there should be three of them. It might be that one of them fell out and got caught in the cam gear, causing it to strip the teeth off and loose time. The bent push rods would be from pistons pushing valves shut. If that is the case, I would replace the gears, and push rods, then run a compression check to see if any of the pistons have holes in them, or maybe more likely valves are bent.
