Leaking injector on my petrol Chrysler 200
It is important to know that the injectors on petrol and diesel engines are different, actually, the difference in combustion between these two types of engines makes the injection different. 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 Chrysler 200: The different leaks
It should be noted that injector leaks on a Chrysler 200 equipped with a petrol engine are pretty infrequent. This is because of the much lower pressure in the petrol intake systems. Nevertheless, 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 part that is attached 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 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 Chrysler 200
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion system generates 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 200: The different leaks
In the circumstance of leaking diesel injectors on your Chrysler 200, there are three different types of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform in the long run, in most cases the leak will be at the clamping point. - Injector return leakage:
As its name suggests, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Chrysler 200 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 experience 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 browse this content page on the existence of oil leaking on your Chrysler 200.
Leaking injector on my Chrysler 200, how to fix the leak
And finally, we’re going to look at how to fix a leaking injector on your car. Frequently a leak is linked, as we have seen previously, to a worn seal caused by the pressures endured. But think that the pressure in the circuit is enormous, specifically on diesel engines. So you will have to take some precautions:
- Lower the pressure before any work is carried out…
- 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 very often be limited 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 assembly and tighten with a torque wrench in respect with the manufacturer’s standards.
In all situations, these interventions are not automatically very hard, but if you have the slightest doubt in the treatment of your injector that leaks on your Chrysler 200, we suggest you to get closer to your repair shop to avoid any bad handling that could critically harm the condition of your Chrysler 200.
