In the event that you are aware of irregular symptoms on your vehicle, you are right to be worried, because a car represents a massive annual budget and unpredicted breakdowns don’t lower the bill. So what if you feel like you have a leaking injector on your Suzuki Vitara? You almost certainly figured it out thanks to black/oily drips along your engine motor, or a disturbed idle, or abnormal black smoke. These three symptoms are the main signals of a leaking injector. As this troubles can bring on more critical engine concerns on your car, we made a decision to write this content to help you validate the failure of a leaking injector and treat it properly. To do so, we will initially check out the case of gasoline injectors and then at those of diesel injectors Suzuki Vitara.


Leaking injector on my petrol Suzuki Vitara

It is fundamental 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 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 Suzuki Vitara: The different leaks

It should be noted that injector leaks on a Suzuki Vitara equipped with a petrol engine are pretty infrequent. 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 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 come from the junction with the engine and not with the rail as seen sooner.

Leaking injector on my diesel Suzuki Vitara

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 Suzuki Vitara: The different leaks

In the case of leaking diesel injectors on your Suzuki Vitara, there are three several types of leaks:

  • Leakage from the injector inlet:
    In cases like this, it is an inlet pipe that will deform with time, generally 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 Suzuki Vitara 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 annoying, 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 verifying you have oil leaking but it does not come from your injectors, we recommend you to browse this content on the existence of oil leaking on your Suzuki Vitara.

Leaking injector on my Suzuki Vitara, how to fix the leak

And at last, we’re going to check out how to fix a leaking injector on your car. Very often 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 measures:

  • Lower the pressure before any work is achieved…
  • Masking 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 very often be limited to changing the seals that have failed:

  • Situate 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 respect with the manufacturer’s standards.

In all situations, these interventions are not inevitably complex, but if you have the smallest doubt in the treatment of your injector that leaks on your Suzuki Vitara, we recommend you to get closer to your auto technician to avoid any bad handling that could critically harm the condition of your Suzuki Vitara.
