Disadvantages of the Jaguar AJ34 engine
- The weak point of this engine is the unreliable phase regulators of the VVT type;
- The motor is aluminum and is afraid of overheating, so keep an eye on the cooling system;
- The crankcase ventilation valve clogs rather quickly, which leads to high oil consumption;
- The search for the culprit of floating engine speeds should start with cleaning the throttle assembly;
- On long runs, antifreeze leaks often occur due to burst pipes.
