Disadvantages of the Mazda L813 engine

  • The main complaints are related to floating turnover, which is difficult to get rid of.
  • The firmware of the control unit helps, cleaning or modification of the throttle assembly.
  • Weaknesses also include the thermostat, pump, alternator and right motor support.
  • Often oil oozes from under the valve cover and goes straight into the spark plug wells.
  • Since there are no hydraulic lifters, every 100,000 km it is necessary to adjust the valves.
