Fuel combustion makes power production possible for the engine. The process of burning the air-fuel mixture, however, also creates harmful by-products: toxic exhaust gases. These gases need to get out of your vehicle; otherwise, the engine can't function as efficiently as possible.The exhaust valve forces out these gases out of the cylinders and directs them into the exhaust manifold. Any valve malfunction can trap the exhaust fumes in the cylinders, which means the engine needs to work doubly hard to expel them, and this results in the loss of engine power.The gases could also cause vital engine parts to corrode and incur damage eventually. So make it a habit to check the exhaust valve regularly. Replace defective valves as soon as you can. It won't be an easy job, but it'll spare you dozens of more serious problems. Quality replacement exhaust valves are available at Carparts.
