Characteristic problems and defects of the E7J engine
Electrical problems:
- Failures due to sensor failure or wiring damage.
- The most common failure is failure of the throttle potentiometer.
Unstable engine operation:
Can be caused by leaking vacuum tubes, a clogged gas pump screen, damage to the timing cover, or air entering through the intake manifold.
Other weaknesses:
- Oil leaks through oil seals and the need to check the condition of the timing belt. Belt breakage leads to serious damage (bent valves).
- Necessity to adjust thermal valve clearances, as the engine is not equipped with hydrocompensators.
Service life
The declared life of the E7J engine is 180 000 km, but in practice, with proper care, the unit can serve up to 300 000 km.
