Disadvantages of the ET3J4 engine
An engine that is generally dependable frequently worries about trivial matters, particularly electrics;
Regular ignition system component failures are the root cause of numerous issues;
A dirty throttle or idle speed controller causes the engine’s speed to float;
Although the timing belt’s rollers may not travel that far, it is intended for 80,000 kilometers;
Any overheating in this area causes burning oil and suffocation of the valve stem seals.
