Disadvantages of the B4184S engine

  • This modification without a phase regulator is the simplest and most reliable motor in the line;
  • Due to clogged crankcase ventilation, a small amount of lubricant is often found here;
  • The timing belt resource is often less than 90,000 km, and when it breaks, the valves bend;
  • It can also bend the valves if a broken alternator belt gets into the timing;
  • In case of engine failures, you need to look at the integrity of the rotor of the camshaft position sensor.
