Can timing belt bent valves?
Andrew Thornton Can timing belt bent valves?
A non-interference engine provides clearance between the valves and pistons, so if the timing belt breaks, you might end up with bent valves, and you might have to have your cylinder heads rebuilt, but the engine isn’t likely to be destroyed. The pistons and the valves “own” the cylinder at different times.
What happens if timing belt jumped?
At minimum a jumped timing belt will cause a noticeable running problem and/or a Check Engine Light. In many cases a jumped timing belt will cause some engine damage. A timing belt can also strip teeth off, shred, or break entirely.
What happens if your valves are bent?
Engine valve problems begin to occur when your engine is subjected to overheating, lack of lubrication or over-revving. Bent valves will not only damage pistons, but also valve guides, camshafts and valve train components.
Can you drive a car with bent valves?
A bent valve could start a fatigue crack in the stem and if it breaks you drop the valve in the cylinder. You could also hammer the seat beyond where a valve job could fix it or (it the exhaust valves are bent) burn the exhaust valve(s) up. I wouldn’t do it.

How do you diagnose a jumped timing belt?
Hook up the timing light to the number one cylinder and start the engine. Aim the timing light at the marks. If the timing marks do not come close to alignment or you do not see any alignment at all, it means the chain has jumped position.
How do you fix a jumped time?
There is no easy way to correct a jumped timing belt. You will need to disassemble a portion of the engine to gain access to the belt tensioner, so you can move the belt back into position. I suggest replacing the belt and tensioners while you have it apart, so you don’t have this problem again.
