OEM GM Engine Parts

Your GM vehicle's engine is made of many parts, each of which is essential to its operation.

The Parts of Your Engine

First, there's the engine block. The other parts connect to it, making it home for the combustion you need. The cylinder head sits on top, preventing oil and gas leaks. Pistons pressurize the oxygen and fuel mixture inside the engine. Intake valves manage the air and fuel levels, while the spark plugs ignite the mixture and exhaust valves regulate the fume levels. The camshaft opens and closes the valves, while a valve cover protects them from harm. Your crankshaft takes the engine power and converts it into the rotary motion that your drive shaft and transmission use to rotate the wheels and tires. Lastly, the oil pan stores the motor oil that lubricates the engine parts.

How to Recognize the Signs of Failing Engine Parts

If your engine parts start to go bad, engine failure may be right around the corner. Fortunately, it's easy to spot the symptoms, which include:

• The "Check Engine" dashboard light comes on
