Disadvantages of the FA24D engine

  • The most famous problem of this unit is failures due to oil starvation.
  • But it is worth noting that all cases of wedge and rotation of the liners occurred on the track.
  • The first hypothesis is a drop in oil pressure when cornering due to a miscalculation by the designers.
  • But some owners, when opening the engine, found sealant in the oil intake.
  • Also, every 100,000 km you will find an expensive procedure for adjusting valve clearances.
