Disadvantages of the 1SZ-FE engine
- This engine is extremely sensitive to quality and especially to the timing of oil changes;
- There is a chain jump and a meeting of valves with pistons due to the wedge of the hydraulic tensioner;
- In severe frost and vice versa, the heat may leak air into the intake manifold;
- Due to the design of the pump, oil is carried through the system for a long time after the engine starts;
- It is very difficult to adjust the valves, since you need to change the entire drive sleeve.
