In the event that you are aware of abnormal symptoms on your automobile, you are right to be concerned, because a car represents a big annual budget and surprising breakdowns don’t lower the costs. So what if you feel as if you have a leaking injector on your PORSCHE PANAMERA? You most likely figured it out thanks to black/oily drips along your engine, 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 end up in more serious engine trouble on your car, we thought we would prepare this article content to help you validate the failure of a leaking injector and treat it correctly. To do so, we will first of all look at the case of gasoline injectors and then at those of diesel injectors PORSCHE PANAMERA.
Leaking injector on my petrol PORSCHE PANAMERA
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 kind of engines makes the injection distinct. The key difference lies in the pressure experienced 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 PORSCHE PANAMERA: The different leaks
It should be known that injector leaks on a PORSCHE PANAMERA 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 kind 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 attached to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:
Finally, 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 before.
Leaking injector on my diesel PORSCHE PANAMERA
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 PORSCHE PANAMERA: The different leaks
In the case of leaking diesel injectors on your PORSCHE PANAMERA, there are three several kind of leaks:
- Leakage from the injector inlet:
In this case, 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 reveals, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your PORSCHE PANAMERA 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 find an air noise and a compression loss. - If after examining you have oil leaking but it does not come from your injectors, we recommend you to consult this article content on the presence of oil leaking on your PORSCHE PANAMERA.
Leaking injector on my PORSCHE PANAMERA, how to fix the leak
And to finish, we’re going to look at how to fix a leaking injector on your car. Oftentimes a leak is linked, as we have seen previously, 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 conducted…
- 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 regularly be restricted 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 respect with the manufacturer’s standards.
In all situations, these interventions are not inevitably complicated, but if you have the slightest hesitation in the treatment of your injector that leaks on your PORSCHE PANAMERA, we recommend you to get closer to your motor mechanic to avoid any bad manipulation that could severely harm the condition of your PORSCHE PANAMERA.
