Bent valves are a common problem that can occur in internal combustion engines. When valves become bent, they can cause a variety of problems, including engine misfires, loss of power, and poor fuel economy. In severe cases, bent valves can even lead to engine damage.
If you suspect that your engine has bent valves, it is important to have them checked and repaired as soon as possible. Checking for bent valves is a relatively simple process that can be done at home with a few basic tools.
Symptoms of Bent Valves
The following are some of the most common symptoms of bent valves:
- Engine misfires
- Loss of power
- Poor fuel economy
- Rough idle
- Backfiring
- Knocking or ticking noises from the engine
Causes of Bent Valves
Bent valves can be caused by a variety of factors, including:

How to Check Cylinder Head for Bent Valves
To check for bent valves, you will need the following tools:
- Valve spring compressor
- Dial indicator
- Straight edge
- Feeler gauge
1. Remove the valve cover.
2. Locate the valve springs.
3. Compress the valve springs using the valve spring compressor.
4. Place the dial indicator on the valve stem.
5. Zero the dial indicator.
6. Rotate the crankshaft slowly while watching the dial indicator.
If the dial indicator moves more than 0.002 inches, the valve is bent.
Repairing Bent Valves
