Related Repair Advice

  • Excessive oil consumption can be caused by sludge buildup on the oil control rings. In some cases, special cleaners can be used to clean the rings without disassembling the engine.
  • While a damaged piston ring can be replaced, it's common to have the engine replaced when piston ring damage is encountered
  • 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
