You should find out if you have an interference engine, if your enging is non-interference then there is no way piston can hit valves and if you do have an interference engine doing a compression test may help figure it out, but if one of the readings is slightly low, you may have a valve that just bent a little. The best way to be certain is to remove them from cylinder head and inspect. If you did smack valves you should also replace the valve keepers and retainers, it is a small price for what can cause a serious engine problem in the future.

Answer 2:

1. Vehicle history. A broken timing belt, chain, or some other big timing problem will probably bend the valves.

2. A severe overrev. Downshift to Second i nstead of Fourth, or something similar. Valve control is lost at extreme RPM.

Otherwise, valves don't just bend themselves.

To check, take off the valve cover, and remove the rocker arms or the camshaft. All of the valve spring retainers should sit at the same height. Use a straightedge.

An engine with bent valves usually will not run.
