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.
