Disadvantages of the Isuzu 4JX1 engine
- This is one of the most problematic Isuzu diesels.
- Most of its breakdowns are related to the vagaries of the unusual HEUI fuel system.
- There are especially many complaints about the ingress of diesel fuel into the oil through nozzle seals.
- Monitor the condition of the timing belt, if it breaks at high speed, the valves bend.
- There are no hydraulic lifters here and periodically you need to adjust the valve clearances.
