Disadvantages of the XU7JP engine
- A signature feature of the XU series motors is unstable operation in cold weather;
- Condensate often freezes in the crankcase ventilation tube and drives oil through the dipstick;
- Engine RPM fluctuates due to idle speed control stepper motor failures;
- Poor-quality gasoline quickly disables spark plugs, and then ignition coils;
- The timing belt often cracks before the prescribed 120,000 km, change it more often;
- There are no hydraulic lifters, so valve clearances have to be adjusted manually;
- The main places for oil leakage are the valve cover and the crankshaft oil seal.
