Do a compression test.
bent valve, burnt valve, stuck valve, broken piston ring, cracked piston, cracked head, blown head gasket.
NO it is an interference motor 180,000 broke timing chain, bent #3 exhaust valve, luckily it must have stopped quickly as no more were bent.
Yes, Chain snapped at 180,000 mile cavalier 2.2 liter bent #3 exhaust valve, which obviously was at the wrong place at the wrong time. 4-10-12

If you have a bent valve slide, or valve, or valve casing, they usually wont move. Valve's and valve casings would prevent the valves from moving, while bent valve slides wont easily pull out. If you suspect a bent valve, valve casing, or slide, try cleaning and oiling it first, valves and slides can become stuck with the lack of valve oil or slide grease.
the valve bent because the piston hit it, due to a weak valve spring or over revving the engine
Yes, it is possible to fix a bent Presta valve by carefully straightening it using a valve tool or pliers. However, if the valve is severely damaged, it may need to be replaced.
check for bent or burnt valve check for bent or burnt valve
yes a bent valve will not seat properly. can also wear the valve slide and ruin the head.will also cause backfiring and loss of power. sometimes a bent valve will breakthen fall down and punch a hole thru the piston or the side of the cylander bore so yes a bent valve can cause further damage to your engine
You don't, you replace it.
IF there is no compression in one or more cylinder, you either have a bent valve, a burned valve or a bad head gasket. In any case, the head must be removed if you plan to repair the engine.
