The symptoms of bent valves include an engine that won’t start, an erratic engine when idling, lack of engine power, a knocking noise from the engine and excessive exhaust fumes. The fuel delivery and gas removal are controlled by engine valves. Bent valve problems can be caused by a number of factors, such as improper installation of the valve, improper fuel injection, or improper maintenance.
The most common cause of a bent valve is a leaky fuel injector, which can occur when fuel is injected into a fuel system that is not designed to handle high levels of fuel. This can cause fuel to leak into the combustion chamber and cause a valve to bend. If the leak is large enough, it can lead to a fire.

Will an engine start with bent valves?
It is most likely not. The result of a timing belt failure is usually bent valves. This can cause catastrophic damage to the engine. In fact, usually even if you try to start the engine, the camshaft will not be turning while the valve is open.
If you do have a bent valve, you will need to replace it with a new one. These are available at most auto parts stores and can be found for as little as $10.00. They are made of plastic, so they are easy to clean, and they come in a variety of colors to match your vehicle’s paint scheme.
What does a bent valve feel like?
Misfiring cylinders together with a check engine light on your dashboard are the most common symptom of a bent engine valve. It’s also a sign that your engine is bent if you see low compression with a compression test.
Can you check valves without removing head?
Your vehicle’s valves are responsible for providing the appropriate amount of pressure in order to perform the correct combustion method. Testing your vehicle’s valve compression can easily detect without having to remove the head- this can avoid you from paying for a replacement valve.
How do you know if your valves are bad?
When you have a bad valve seal, the oil that collects at the front cover of the head will end up burning when you push on the accelerator after coasting for a while. This can be seen when going downhill and again by the excessive smoke coming from the intake manifolds.
This is a common problem that can be fixed by replacing the valve cover gasket with a new one. It is also possible to replace the camshaft seals with new ones, but this is not recommended as it will void the engine warranty.
Can bent valves cause misfire?
Bent or burnt valves can also cause your engine to misfire. When your car is in motion, the engine may jerk, stall, or hesitate. A bad valve could cause your vehicle’s fuel consumption to increase.
Do valves always bend when a timing belt breaks?
If the timing belt breaks, non-ference engines don’t suffer any damage. When you replace the timing belt kit, the engine stalls and you are good to go. Older engine models have valves that bend when the timing belts are worn out. If you have an interference engine, it’s a good idea to check the engine’s oil level before you start the car.
If the oil levels are low, your engine will stall and you’ll have to start over with a new engine. This is especially true if you’ve been using oil that’s been sitting in your car for a long time. You’ll also want to make sure that your oil filter is clean and free of dirt and debris.
