Engine Cylinder

Engine cylinders are machined round bores (tubes) inside the engine block that house the pistons. As the engine operates, the pistons move up and down within the cylinders.

Symptoms of Wear or Failure

  • Engine misfire
  • Excessive oil consumption
  • Engine overheating

Related Repair Advice

  • Engine replacement is often recommend when problems are encountered with a cylinder
  • A "short block" replacement may also be recommended—this replacement only includes the lower parts of the engine and leaves out the cylinder head and intake manifold
  • The cylinders may be machined inserts (sleeves) that are fit into the engine block or cast and machined as an integral part of the engine block
