OEM Subaru Engine Parts

The factory engine at the heat of your Subaru vehicle is composed of several parts that all work together to produce the power you need. Those Subaru engine parts also help move other components your vehicle needs to operate properly.

The Parts of Your Engine

Your engine block is the hub that connects everything, and home to the combustion that creates power. The pistons pump up and down to compress and pressurize the air-fuel mix inside the engine block. A cylinder head sits on top of the engine block, with head gaskets providing a seal between the two. That keeps the combustion gases contained within the engine block. Assorted valves, spark plugs, and other pieces connect to the cylinder head. A camshaft opens and closes those valves in sync with the other moving parts. Your crankshaft converts the engine's pumping motion into the rotary motion that turns your tires. Then there are the many other pieces, such as gaskets, rings, gears, and bearings, that piece everything together.

How to Spot Engine Parts Trouble

Eventually engine parts can wear out, weaken, or go bad. Signs of this include:

  • Problems accelerating
  • Uneven idling
  • Engine stalls
  • Suffering fuel efficiency
