Disadvantages of the EW7J4 engine
- Most of the problems of the power unit are somehow related to lubricant leaks;
- Oil likes to ooze from under the valve cover, leak from the breather, or just burn out;
- In second place are frequent failures of ignition system components, especially coils;
- The culprit of the floating engine speed is contamination of the throttle or idle speed controller;
- After 100,000 km, engine mounts and hydraulic lifters often require replacement.
