What to Know About Valves and Parts
Overhead valve engines and camshaft engines share similar and different valves and parts. Overhead valve engine parts include valve springs, rocker arms, pushrods, and lifters. Overhead camshaft engine parts include valve springs, rocker arms, and lifters. The main difference between these engine parts is the location of the camshaft.
In an overhead camshaft engine, the camshaft is on the top of the engine and lacks pushrods. In an overhead valve engine, the camshaft is below the head and includes pushrods. The type of valves and parts you need for your vehicle may vary depending on your engine type.
The two parts of an engine valve are the valve stem and the valve head. If your engine valves are bad, you might see blue exhaust smoke or an oil leak under your vehicle, and you might experience excessive oil consumption, loss of power, or rough idling.
