Disadvantages of the ET3J4 engine
- A generally reliable engine often worries about trifles, especially about electrics;
- Many problems are caused by regular failures of the components of the ignition system;
- Engine speed floats due to a dirty throttle or idle speed controller;
- The timing belt is designed for 80 thousand km, but its rollers may not pass that much;
- Any overheating here leads to suffocation of the valve stem seals and burning oil.
