In cases where you are alert of unusual signs on your car, you are right to be preoccupied, because a car represents a huge annual budget and unforeseen malfunctions don’t reduce the bill. So what if you feel as if you have a leaking injector on your Chrysler Sebring? You almost certainly figured it out thanks to black/oily drips along your engine unit, or a troubled idle, or strange black smoke. These three symptoms are the main signs of a leaking injector. As this troubles can cause more critical engine problems on your car, we decided to write this article to help you ensure the failure of a leaking injector and deal with it properly. To achieve this, we will first of all look at the circumstance of gasoline injectors and then at those of diesel injectors Chrysler Sebring.
Leaking injector on my petrol Chrysler Sebring
It is crucial to know that the injectors on petrol and diesel engines are distinct, in fact, the difference in combustion between these two kind of engines makes the injection distinct. The main 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 Chrysler Sebring: The different leaks
It should be noted that injector leaks on a Chrysler Sebring equipped with a petrol engine are rather rare. This is caused by the much lower pressure in the petrol intake systems. However, there are two kind 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 component that is connected 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 portion of the injector of your car, this one will come from the junction with the engine and not with the rail as seen previously.
Leaking injector on my diesel Chrysler Sebring
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 Chrysler Sebring: The different leaks
In the circumstance of leaking diesel injectors on your Chrysler Sebring, there are three different kind of leaks:
- Leakage from the injector inlet:
In this instance, it is an inlet pipe that will deform with time, commonly 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 Chrysler Sebring 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 feel an air noise and a compression loss. - If after examining you have oil leaking but it does not come from your injectors, we suggest you to browse this article on the presence of oil leaking on your Chrysler Sebring.
Leaking injector on my Chrysler Sebring, how to fix the leak
And at last, we’re going to look at how to fix a leaking injector on your car. Oftentimes a leak is linked, as we have seen prior to this, to a worn seal because of the pressures suffered. But think that the pressure in the circuit is monumental, especially on diesel engines. So you will have to take some measures:
- Lower the pressure before any work is completed…
- 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 regularly be limited to swapping the seals that have failed:
- Find the source of the leak
- Take apart 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 situations, these interventions are not automatically complicated, but if you have the tiniest uncertainty in the treatment of your injector that leaks on your Chrysler Sebring, we suggest you to get closer to your auto technician to avoid any bad manipulation that could significantly harm the condition of your Chrysler Sebring.
