Commonly Asked Questions About Engine Parts

• What makes up most factory engines? A block, a cylinder head, and several cylinders, most often, with pistons for every cylinder. Also, valves and valve covers, a camshaft and crankshaft, spark plugs, and either an oil pan or an oil sump.
• What does each do?
  The valve covers and cylinder head seal the engine block, which helps protect the valves and other parts and helps prevent gas and oil from leaking.
  The intake valves manage the engine's air and fuel ratio, while the exhaust valves adjust fume levels in the engine.
  The camshaft coordinates valve activity.
  The pistons compress the engine's mixture of gas and oxygen, while spark plugs combust the mix initially.
  The crankshaft turns the resulting power into rotary motion, and the driveshaft and transmission use it to turn the wheels and tires.
  The oil sump or oil pan stores the motor oil, which the engine uses to lubricate its parts as it runs.
  Many other components -- sprockets and rings, gears and bearings, and more -- ensure proper fitment.
• What are the signs of problems with one or another? Feel for idling and acceleration issues, and look for worsening fuel efficiency, stalling, and not being able to start your vehicle at all. If you need to order parts for repairs, be sure they're genuine.
• Why buy genuine OEM? They're designed to fit the BMW model you drive, whether it's a car or an SUV -- a guarantee that the aftermarket can't always make.
