Disadvantages of the GM LFY engine

  • This is a very reliable engine, but it requires oil changes as often as possible.
  • If you update the lubricant according to the regulations, then the timing chain tensioners will not last long.
  • Like all direct injection units, it suffers from carbon deposits on the intake valves.
  • All engines of this series are very afraid of overheating, and radiators, as luck would have it, regularly leak.
  • And an even bigger recall campaign for the High Feature engine touched this motor as well.
