In the event that you are informed of abnormal symptoms on your vehicle, you are right to be concerned, because a car represents a big annual budget and sudden breakdowns don’t reduce the expenses. So what if you find that you have a leaking injector on your Mitsubishi Eclipse? You most likely figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or strange black smoke. These three manifestations are the main signals of a leaking injector. As this problem can end up in more severe engine trouble on your car, we chose to compose this content page to help you confirm the failure of a leaking injector and deal with it properly. To accomplish this, we will first of all look at the circumstance of gasoline injectors and then at those of diesel injectors Mitsubishi Eclipse.
Leaking injector on my petrol Mitsubishi Eclipse
It is fundamental to know that the injectors on petrol and diesel engines are distinct, actually, the difference in combustion between these two sort of engines makes the injection distinct. The essential 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 Mitsubishi Eclipse: The different leaks
It should be said that injector leaks on a Mitsubishi Eclipse equipped with a petrol engine are pretty infrequent. This is as a result of the much lower pressure in the petrol intake systems. Even so, there are two sort of leaks:
- Leakage from the top of the injector:
It is plausible 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:
At last, you may suffer a leak coming from the lower part of the injector of your car, this one will appear from the junction with the engine and not with the rail as seen before.
Leaking injector on my diesel Mitsubishi Eclipse
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 Mitsubishi Eclipse: The different leaks
In the circumstance of leaking diesel injectors on your Mitsubishi Eclipse, there are three several sort 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 suggests, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Mitsubishi Eclipse 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 consult this content page on the presence of oil leaking on your Mitsubishi Eclipse.
Leaking injector on my Mitsubishi Eclipse, how to fix the leak
And to finish, we’re going to look at how to fix a leaking injector on your car. Frequently a leak is connected, as we have seen sooner, to a worn seal as a result of the pressures endured. But think that the pressure in the circuit is enormous, specifically on diesel engines. So you will have to take some safety measures:
- Lower the pressure before any work is done…
- 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 swapping the seals that have failed:
- Locate 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 accordance with the manufacturer’s standards.
In all cases, these interventions are not necessarily very hard, but if you have the smallest doubt in the treatment of your injector that leaks on your Mitsubishi Eclipse, we suggest you to get closer to your repair shop to avoid any bad manipulation that could significantly harm the condition of your Mitsubishi Eclipse.
