Bent valves are a serious engine problem that can occur when the valves in the cylinder head are forced out of alignment, causing them to make contact with the piston. This can happen due to a number of factors, including a timing belt failure, a valve spring failure, or an engine overheating.
Checking for bent valves is a relatively simple process that can be performed at home with a few basic tools. The first step is to remove the valve cover and inspect the valves for any visible damage. If the valves appear to be bent, you will need to remove the cylinder head and inspect the valves more closely.
