Disadvantages of the 4G63T engine
The condition of the balance shafts is rapidly impacted by the use of inferior oil;
The shaft’s wedge causes their belt to break, falling beneath the timing belt and the motor’s end;
The power unit’s pillow resource is reduced by multiple times due to vibrations of the balancers;
Floating speed is caused by a dirty throttle or idle control;
Cracked exhaust and intake manifolds are a problem for many owners.
