In the event that you are alert of unusual symptoms on your automobile, you are right to be worried, because a car represents a huge annual budget and sudden breakdowns don’t reduce the costs. So what if you find that you have a leaking injector on your Peugeot Rifter? You almost certainly figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or abnormal black smoke. These three signs of illness are the main signals of a leaking injector. As this failure can lead to more severe engine problems on your car, we thought we would compose this content page to help you verify the failure of a leaking injector and deal with it correctly. To accomplish this, we will initially look into the case of gasoline injectors and then at those of diesel injectors Peugeot Rifter.


Leaking injector on my petrol Peugeot Rifter

It is fundamental to know that the injectors on petrol and diesel engines are distinct, actually, the difference in combustion between these two types of engines makes the injection distinct. The essential 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 Rifter: The different leaks

It should be said that injector leaks on a Peugeot Rifter 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 conceivable that you have a leak from the top of the injector, this is the portion that is linked to the fuel rail, an O-ring will be involved in this.
  • Leak injector of the lower part:
    At last, 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 sooner.

Leaking injector on my diesel Peugeot Rifter

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 Rifter: The different leaks

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

  • Leakage from the injector inlet:
    In cases like this, it is an inlet pipe that will deform in the long run, usually 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 Peugeot Rifter 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 encounter 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 read this content page on the existence of oil leaking on your Peugeot Rifter.

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

And at last, we’re going to look into how to fix a leaking injector on your car. Oftentimes 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 tremendous, specifically on diesel engines. So you will have to take some 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.

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

  • Find 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 specifically difficult, but if you have the smallest uncertainty in the treatment of your injector that leaks on your Peugeot Rifter, we suggest you to get closer to your repair shop to avoid any bad handling that could seriously harm the condition of your Peugeot Rifter.
