How much does it cost to overhaul the Great Wall Feng Jun 3 diesel pickup truck?

Not Isuzu's. The engine of Feng Jun 3 is the engine of our factory. If it exceeds 6w, it won't work. If it exceeds 8w, it is electro-jet, which is useless and has poor adaptability to oil quality. As we all know, the quality of diesel in our country is not good, and EFI is useless, so a bad injector will be replaced, which is about 654.38+0 million yuan.
