Disadvantages of the Mazda GY-DE engine
Although the motor is well-known for its longevity and dependability, it uses a lot of fuel.
The tank has a regular mesh that clogs easily in place of a fuel filter.
The fuel pump and fuel injectors will soon fail if the mesh is clogged.
The location makes it challenging to replace the water pump, which serves very little.
Oil leaks, particularly from beneath the cylinder head’s top cover, are the cause of the remaining issues.
