OEM Infiniti Engine Parts

Your INFINITI engine has many parts at work, and each is responsible for something important. When working right, they team up to deliver the power you need to drive down the road.

The Parts of Your Engine

The cylinder head, for example, helps keep gases contained and prevents oil leaks. Pistons pump vertically to pressurize the mixture of fuel and air that the engine consumes. Intake valves manage their levels, as spark plugs provide the initial flash you need for combustion and exhaust valves regulate the fume levels. Your valve covers shield the engine's valves from harm, while a camshaft opens and closes the valves. A crankshaft turns the pistons' motion into rotary motion that your transmission and drive shaft use to move your wheels. The oil pan, or oil sump, contains the motor oil that lubricates the engine parts.

How to Spot Failing Engine Parts

Sadly, even the best engine parts can wear down or go bad. Signs of this include:

• Uneven engine idling
• Trouble accelerating
• Fuel efficiency suffers
• Stalling engine
• Your "Check Engine" light comes on
