In the event you are aware of abnormal signs on your automobile, you are right to be worried, because a car represents a massive annual budget and sudden malfunctions don’t reduce the bill. So what if you feel like you have a leaking injector on your Ram P/U? You likely figured it out thanks to black/oily drips along your engine unit, or a troubled idle, or strange black smoke. These three signs of illness are the main signals of a leaking injector. As this failure can bring on more critical engine problems on your car, we thought we would compose this content to help you ensure the failure of a leaking injector and treat it properly. To achieve this, we will initially take a look at the circumstance of gasoline injectors and then at those of diesel injectors Ram P/U.


Leaking injector on my petrol Ram P/U

It is vital to know that the injectors on petrol and diesel engines are different, in fact, the difference in combustion between these two types of engines makes the injection different. The essential 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 Ram P/U: The different leaks

It should be known that injector leaks on a Ram P/U equipped with a petrol engine are pretty infrequent. This is because of 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 possible that you have a leak from the top of the injector, this is the component that is linked to the fuel rail, an O-ring will be involved in this.
  • Leak injector of the lower part:
    Finally, you may experience a leak coming from the lower portion of the injector of your car, this one will come from the junction with the engine and not with the rail as seen before.

Leaking injector on my diesel Ram P/U

Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure creates 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 Ram P/U: The different leaks

In the circumstance of leaking diesel injectors on your Ram P/U, there are three several types of leaks:

  • Leakage from the injector inlet:
    In this instance, it is an inlet pipe that will deform with time, commonly the leak will be at the clamping point.
  • Injector return leakage:
    As its name reveals, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Ram P/U 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.
  • If after verifying you have oil leaking but it does not come from your injectors, we recommend you to browse this content on the presence of oil leaking on your Ram P/U.

Leaking injector on my Ram P/U, how to fix the leak

And to finish, we’re going to take a look at how to fix a leaking injector on your car. Regularly a leak is connected, as we have seen sooner, to a worn seal as a result of the pressures suffered. But think that the pressure in the circuit is enormous, specifically on diesel engines. So you will have to take some precautions:

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

Relating to the repair part of your leak, it will frequently be restricted to replacing the seals that have failed:

  • Discover the source of the leak
  • Dismantle the injector in question
  • Change the corresponding seal kit
  • Reassemble the set up and tighten with a torque wrench in respect with the manufacturer’s standards.

In all cases, these interventions are not inevitably complicated, but if you have the tiniest doubt in the treatment of your injector that leaks on your Ram P/U, we recommend you to get closer to your auto mechanic to avoid any bad manipulation that could severely harm the condition of your Ram P/U.
