Disadvantages of the EZ36 engine
- Most often, the network complains about high fuel consumption and regular oil leaks;
- In second place is overheating due to another problem with the cooling system;
- From cheap oil, the tensioner fails here and the timing chain starts to make noise;
- Low reliability also has a pressure regulator in the fuel pump;
- On runs over 150 – 200 thousand km, oil consumption for waste is often already present.
