Disadvantages of the HYDB engine
The primary issues brought on by the crankcase ventilation system’s PCV valve contamination;
Replacing its membrane helps with the motor’s howl and leaks from the camshaft seals;
Pulling with a replacement will cause oil to seep onto the timing belt, shortening its lifespan;
Spark plugs, coils, and a gasoline pump rapidly fail as a result of poor fuel;
After a run of roughly 100,000 kilometers, some owners were forced to replace the turbine.
