Disadvantages of the Jaguar AJ33S engine
Keep an eye on the cooling system because this aluminum motor is afraid of overheating;
A tiny resource is available to the compressor water pump;
Here, the crankcase ventilation valve rapidly clogs, resulting in a significant lubricant consumption;
The engine speed will float if the throttle and injectors are not cleaned on a regular basis; additionally, different nozzles frequently burst, causing air leaks.
