Disadvantages of the Y26SE engine
- A known weak point of this unit is the constantly leaking heat exchanger.
- Also, a lot of trouble is caused by the unreliable crankcase ventilation system.
- After 250,000 km, the performance of the oil pump decreases, which is dangerous for the engine.
- It is important to monitor the cooling system; if it overheats, it immediately breaks through the cylinder head gaskets.
- The remaining problems are associated with failures of the ignition coils, lambda probes and crankshaft position sensor.
