Disadvantages of the Jaguar AJ30 engine
- This motor is highly reliable, but spare parts for it are expensive.
- The main problems are associated with suction in the intake due to cracked gaskets.
- Also, the electric drive for changing the intake geometry is characterized by low reliability.
- If you do not regularly clean the crankcase ventilation valve here, then the oil will press from all the cracks.
- On runs over 200 thousand km, lubricant consumption may appear due to the occurrence of rings.
