Leaking injector on my petrol hyundai i30

It is vital 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 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 hyundai i30: The different leaks

It should be said that injector leaks on a hyundai i30 equipped with a petrol engine are rather rare. This is resulting from 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 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 part of the injector of your car, this one will appear from the junction with the engine and not with the rail as seen before.

Leaking injector on my diesel hyundai i30

Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure 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 hyundai i30: The different leaks

In the circumstance of leaking diesel injectors on your hyundai i30, there are three several types of leaks:

  • Leakage from the injector inlet:
    In this instance, it is an inlet pipe that will deform over time, in most cases the leak will be at the clamping point.
  • Injector return leakage:
    As its name implies, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your hyundai i30 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.

Leaking injector on my hyundai i30, 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. Oftentimes a leak is associated, as we have seen prior to this, to a worn seal as a result of the pressures endured. But think that the pressure in the circuit is tremendous, especially on diesel engines. So you will have to take some safety measures:

  • 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.

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

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