Disadvantages of the GM LAF engine

  • The most famous problem of this power unit is high oil consumption.
  • Oil burning due to the occurrence of rings can occur on runs of less than 100 thousand km.
  • Another weak point of the engine is the capricious crankcase ventilation system.
  • The timing chain does not have a high resource, it is often changed even up to 150,000 km.
  • Like all direct-injection combustion engines, intake valves quickly overgrow with soot.
