Disadvantages of the Mazda R2AA engine
The most well-known issue is the increase in oil levels following soot burning;
The sealing washers beneath the nozzles frequently burn out due to a gas breakthrough;
The valve bends when the timing chain jumps up to 100,000 kilometers;
The position sensor in the turbine and the SCV valve in the high pressure fuel pump are further flaws;
Here, you must use special screws to adjust the valves once every 100,000 kilometers.
