OEM Mazda Engine Parts

Refine Results

The main parts of an engine range from a block, a cylinder head, cylinders, pistons, and valves to valve covers, a crankshaft, and a camshaft, spark plugs, and an oil sump or oil pan. Each does something different, and they're all important.

  • Cylinder heads help prevent oil leaks and gases escaping.
  • Pistons pressurize the fuel and oxygen in the engine.
  • Intake valves regulate the engine's fuel and oxygen levels.
  • Spark plugs are what combust that fuel and oxygen.
  • Exhaust valves regulate the engine's fume levels.
  • Valve covers shield the engine's valves.
  • Camshafts help coordinate engine valve activity.
  • Crankshafts turn engine power into rotary motion, which a drive shaft and transmission transform into wheel and tire spin.

Many other engine parts ensure everything fits together the way it ought to. If any of them wear out, engine failure often follows. Luckily, there are signs you can watch for, including:

  • A Check Engine light on your dashboard
  • Increased exhaust
  • Performance problems, such as reduced fuel economy, difficulty getting up to speed, and longer engine warm-up times
  • Roughening idling
  • Stalls
  • Being unable to start your vehicle at all

Noticing any? Do a thorough inspection to determine their causes.
