Disadvantages of the GM LSJ engine

  • Most of the complaints about this unit are associated with jumping idle speeds.
  • In some cases, you have to clean the throttle and intake every 10,000 km.
  • In second place is squeezing oil through the dipstick during sharp acceleration from a standstill.
  • The weak points of this motor also include not the highest resource of the timing chain.
  • And don’t forget to renew the oil in the compressor or it won’t last very long.
