Leaking injector on my petrol Dodge Ram

It is fundamental to know that the injectors on petrol and diesel engines are distinct, in fact, the difference in combustion between these two types of engines makes the injection distinct. The key difference lies in the pressure experienced by the injectors, on a petrol engine it will vary between 3.5 bars for indirect injection and 120 bars for indirect injection.

Leaking injector on a petrol Dodge Ram: The different leaks

It should be noted that injector leaks on a Dodge Ram equipped with a petrol engine are rather rare. This is as a result of the much lower pressure in the petrol intake systems. Nevertheless, there are two types of leaks:

  • Leakage from the top of the injector:
    It is conceivable 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:
    At last, you may encounter a leak coming from the lower portion of the injector of your car, this one will occur from the junction with the engine and not with the rail as seen sooner.

Leaking injector on my diesel Dodge Ram

Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion system produces very high pressure in the engine, as do the injectors. On these models, the pressure is more than 10 times higher than on the direct injection of car petrol engines, reaching 1800 to 2000 bars.

Leaking injector on diesel Dodge Ram: The different leaks

In the case of leaking diesel injectors on your Dodge Ram, there are three several types of leaks:

  • Leakage from the injector inlet:
    In this instance, it is an inlet pipe that will deform along with time, usually the leak will be at the clamping point.
  • Injector return leakage:
    As its name implies, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Dodge Ram will be the result of an O-ring or its plastic tip that leaks.
  • Injector base leak:
    This injection leak is one of the most annoying, it is the junction between the engine and the injector nose that leaks at a copper seal, you should experience an air noise and a compression loss.

And finally, we’re going to take a look at how to fix a leaking injector on your car. Very often a leak is connected, as we have seen sooner, to a worn seal due to the pressures endured. But think that the pressure in the circuit is enormous, especially on diesel engines. So you will have to take some safety measures:

  • Lower the pressure before any work is achieved…
  • Covering you to avoid the risk of fuel spillage
  • NEVER work on a running diesel engine injector.

Concerning the repair part of your leak, it will frequently be limited to changing the seals that have failed:

  • Find out the source of the leak
  • Dismantle the injector in question
  • Replace the corresponding seal kit
  • Reassemble the assembly and tighten with a torque wrench in accordance with the manufacturer’s standards.
