Leaking injector on my petrol Chevrolet Traverse

It is essential to know that the injectors on petrol and diesel engines are different, the reality is, the difference in combustion between these two types of engines makes the injection different. The key difference lies in the pressure undergone 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 Chevrolet Traverse: The different leaks

It should be known that injector leaks on a Chevrolet Traverse equipped with a petrol engine are pretty infrequent. This is caused by 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 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 suffer a leak coming from the lower part 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 Chevrolet Traverse

Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion system 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 Chevrolet Traverse: The different leaks

In the circumstance of leaking diesel injectors on your Chevrolet Traverse, 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, generally the leak will be at the clamping point.
  • Injector return leakage:
    As its name indicates, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Chevrolet Traverse will be brought on by an O-ring or its plastic tip that leaks.
  • Injector base leak:
    This injection leak is one of the most bothersome, it is the junction between the engine and the injector nose that leaks at a copper seal, you should find an air noise and a compression loss.

Leaking injector on my Chevrolet Traverse, how to fix the leak

And to finish, we’re going to 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 caused by the pressures suffered. But think that the pressure in the circuit is tremendous, specifically on diesel engines. So you will have to take some safety measures:

  • Lower the pressure before any work is completed…
  • 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 regularly be limited to swapping the seals that have failed:

  • Situate the source of the leak
  • Take apart the injector in question
  • Replace 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 automatically very hard, but if you have the slightest hesitation in the treatment of your injector that leaks on your Chevrolet Traverse, we encourage you to get closer to your auto mechanic to avoid any bad manipulation that could critically harm the condition of your Chevrolet Traverse.
