Leaking injector on a petrol Dodge Challenger: The different leaks
It should be mentioned that injector leaks on a Dodge Challenger equipped with a petrol engine are pretty infrequent. This is caused by the much lower pressure in the petrol intake systems. However, there are two types of leaks:
- Leakage from the top of the injector:
It is plausible that you have a leak from the top of the injector, this is the portion that is attached to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:
