The Best Toyota Engine Parts

What are the Main Parts of an Engine?

There are many, ranging from a block, a cylinder head, cylinders, pistons and valves to valve covers, a crankshaft, a camshaft, spark plugs, and an oil sump or pan. Each has a different but important job.

What are the Functions of Each Engine Part?

• The cylinder head helps prevent gas and oil leakage.
• The pistons pressurize the engine's mix of fuel and oxygen.
• The spark plugs ignite the mixture for the engine to burn.
• Intake valves regulate the engine's air and fuel levels.
• Exhaust valves regulate the engine's fume levels.
• Valve covers shield engine valves.
• The camshaft helps coordinate valve activity.
• The crankshaft turns power into rotational motion.
• A drive shaft and transmission transform rotary motion into wheel and tire spin.

Many other parts ensure engines fit together properly. If any of them wear out, though, engine problems follow. Luckily, there are symptoms you can look for.

Signs of Engine Failure

• An illuminated Check Engine light
• Increased exhaust emissions
• Performance issues, like a drop in fuel economy, difficulty getting up to speed, and longer warm-up times
• Idling roughly
• Stalling
• Being unable to start your vehicle
