To properly inflate a tire with a bent presta valve, first straighten the valve carefully using pliers. Then, attach the pump securely to the valve and inflate the tire to the recommended pressure. Be gentle to avoid further damage to the valve.
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.
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
possible bent, warped, or torched valve - bad valve seat - or worn valve guide
Sounds like the valves are not closing properly. Something in the valve train is damaged. Could be a bent or broken valve, broken valve spring, broken or bent rocker arm, bent push rod, etc. Low compression combined with back firing thru intake would indicate a damaged intake valve component and back firing thru the exhaust would indicate a damaged exhaust valve.
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
The bent valve won't be able to seat properly to create a seal, so the cylinder won't hold compression. The end result, a dead cylinder.
check for bent or burnt valve check for bent or burnt valve
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.
Broken valve spring, bent valve, rocker arm fell of, hole in piston, rings, etcBroken valve spring, bent valve, rocker arm fell of, hole in piston, rings, etc
no
Do a compression test.
