Leaking injector on my petrol Peugeot Rcz

It is vital 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 main 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 Peugeot Rcz: The different leaks

It should be known that injector leaks on a Peugeot Rcz equipped with a petrol engine are rather rare. This is resulting from 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 connected 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 come from the junction with the engine and not with the rail as seen sooner.

Leaking injector on my diesel Peugeot Rcz

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 Peugeot Rcz: The different leaks

In the circumstance of leaking diesel injectors on your Peugeot Rcz, there are three different types of leaks:

  • Leakage from the injector inlet:
    In this case, it is an inlet pipe that will deform over time, usually the leak will be at the clamping point.
  • Injector return leakage:
    As its name suggests, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Peugeot Rcz 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 bothersome, it is the junction between the engine and the injector nose that leaks at a copper seal, you should feel an air noise and a compression loss.
  • If after verifying you have oil leaking but it does not come from your injectors, we suggest you to consult this article content on the existence of oil leaking on your Peugeot Rcz.

Leaking injector on my Peugeot Rcz, how to fix the leak

And finally, we’re going to check out how to fix a leaking injector on your car. Regularly 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 tremendous, 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 oftentimes be restricted to swapping the seals that have failed:

  • Discover 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 situations, these interventions are not necessarily very hard, but if you have the smallest doubt in the treatment of your injector that leaks on your Peugeot Rcz, we suggest you to get closer to your auto technician to avoid any bad handling that could seriously harm the condition of your Peugeot Rcz.
