Disadvantages of the Mazda GY-DE engine
- The motor is famous for its reliability and long life, but the fuel consumption is rather big.
- Instead of a fuel filter in the tank, there is a regular mesh that quickly clogs.
- If the mesh is clogged, then the fuel pump and fuel injectors quickly fail.
- The water pump serves quite little, and its replacement is difficult due to the location.
- The rest of the problems are related to oil leaks, especially from under the top cover of the cylinder head.
