The main parts of an engine are its block, cylinder head, cylinders, and pistons. Other parts include valves, valve covers, a crankshaft, a camshaft, spark plugs, and an oil sump or oil pan. Each has a different job.

Cylinder heads, for instance, help keep gas and oil from leaking. Pistons, however, pressurize an engine's gas and oxygen. Intake valves regulate the engine's air-to-fuel ratio, while exhaust valves regulate its fume levels. Valve covers protect valves, camshafts help synchronize valve activity, crankshafts turn power into rotary motion, and spark plugs ignite the engine's oxygen and gas, which produce power as they burn. Your drive shaft and transmission, on the other hand, use rotary motion to turn wheels and spin tires.

Many other engine parts ensure proper fitment. If any wear out, engine trouble usually follows. Luckily, there are signs of it that you can keep an eye out for, including trouble accelerating and idling, reduced fuel efficiency, stalling, and the inability to start your vehicle. Seeing any such symptoms? Do an inspection. It'll help you figure out their causes.
