These little guys basically control the flow of exhaust gases out of your engine. They open and close, timed perfectly with the engine’s cycle, to let the burnt fuel and air escape. There are usually multiple of them per engine – one for each cylinder, generally. They don’t just open and close randomly though, a camshaft dictates when and how far they open. It’s a pretty precise operation. Think of it as one part of a larger system that gets rid of the waste products from combustion. The exhaust valve works alongside the intake valve, the pistons, and the camshaft to make the whole engine cycle work efficiently. It's directly involved in how much power your engine can make and how cleanly it runs. It’s responsible for letting the “bad air” out so fresh air and fuel can come in and repeat the process. If an exhaust valve fails, you’ll notice it. You might get a loss of power, rough idling, a misfire, or even a check engine light. Sometimes you'll hear a ticking sound. It can also lead to more serious issues like engine damage if it’s not addressed. A good exhaust valve acts like a shield, protecting the rest of the engine from overheating and maintaining performance. They take a lot of heat and stress, so they do eventually wear out. If you’re doing a head job or rebuilding an engine, it’s always smart to replace the exhaust valves along with the guides and seals.
