Leaking injector on my petrol Chevrolet Aveo

It is crucial to know that the injectors on petrol and diesel engines are distinct, the truth is, the difference in combustion between these two types of engines makes the injection distinct. The biggest 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 Aveo: The different leaks

It should be said that injector leaks on a Chevrolet Aveo equipped with a petrol engine are rather rare. This is because of the much lower pressure in the petrol intake systems. Even so, 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 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 part of the injector of your car, this one will occur from the junction with the engine and not with the rail as seen previously.

Leaking injector on my diesel Chevrolet Aveo

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 Chevrolet Aveo: The different leaks

In the circumstance of leaking diesel injectors on your Chevrolet Aveo, there are three several types of leaks:

  • Leakage from the injector inlet:
    In cases like this, it is an inlet pipe that will deform along with time, in most cases 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 Aveo 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 troublesome, 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 checking you have oil leaking but it does not come from your injectors, we suggest you to consult this article content on the presence of oil leaking on your Chevrolet Aveo.

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

And at last, we’re going to take a look at how to fix a leaking injector on your car. Frequently a leak is connected, as we have seen prior to this, to a worn seal as a result of the pressures suffered. But think that the pressure in the circuit is monumental, especially on diesel engines. So you will have to take some 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.

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

  • Identify 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 situations, these interventions are not specifically complicated, but if you have the tiniest hesitation in the treatment of your injector that leaks on your Chevrolet Aveo, we suggest you to get closer to your mechanic to avoid any bad handling that could significantly harm the condition of your Chevrolet Aveo.
