Disadvantages of the Mazda R2AA engine
- The most famous problem is the rise in oil level after burning a soot;
- Often there is a burnout of the sealing washers under the nozzles with a breakthrough of gases;
- The timing chain can stretch to a mileage of 100 thousand km, and when it jumps, the valve bends;
- Weaknesses also include the SCV valve in the high pressure fuel pump and the position sensor in the turbine;
- Once every 100,000 km, here you need to adjust the valves using special screws.
