Disadvantages of the 3SZ-VE engine
- The motor is demanding on the quality of lubrication, bad oil accelerates its wear at times;
- When the hydraulic tensioner is loosened, the chain jumps and the valves hit the pistons;
- When operating in severe frost or heat, air leakage in the intake is possible;
- Due to the design of the pump, the lubricant spreads through the system for a long time after starting the engine;
- The drive belt of mounted units wears out quickly, but it is not cheap.
