If you are aware of unusual signs on your car, you are right to be worried, because a car represents a massive annual budget and sudden breakdowns don’t reduce the expenses. So what if you think that you have a leaking injector on your Mitsubishi Space star 2? You most likely figured it out thanks to black/oily drips along your engine, or a disturbed idle, or unconventional black smoke. These three symptoms are the main signs of a leaking injector. As this problem can lead to more critical engine concerns on your car, we chose to compose this content to help you confirm the failure of a leaking injector and treat it correctly. To achieve this, we will initially check out the circumstance of gasoline injectors and then at those of diesel injectors Mitsubishi Space star 2.
Leaking injector on my petrol Mitsubishi Space star 2
It is important to know that the injectors on petrol and diesel engines are different, actually, the difference in combustion between these two sort of engines makes the injection different. 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 Mitsubishi Space star 2: The different leaks
It should be known that injector leaks on a Mitsubishi Space star 2 equipped with a petrol engine are rather infrequent. This is caused by 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 part 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 portion of the injector of your car, this one will occur from the junction with the engine and not with the rail as seen sooner.
Leaking injector on my diesel Mitsubishi Space star 2
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure creates 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 Space star 2: The different leaks
In the circumstance of leaking diesel injectors on your Mitsubishi Space star 2, there are three several sort of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform with time, in most cases the leak will be at the clamping point. - Injector return leakage:
As its name indicates, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Mitsubishi Space star 2 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 bothersome, 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 encourage you to consult this content on the existence of oil leaking on your Mitsubishi Space star 2.
Leaking injector on my Mitsubishi Space star 2, how to fix the leak
And finally, we’re going to check out how to fix a leaking injector on your car. Frequently a leak is connected, as we have seen previously, to a worn seal as a result of the pressures endured. But think that the pressure in the circuit is monumental, 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 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 accordance with the manufacturer’s standards.
In all cases, these interventions are not necessarily complicated, but if you have the slightest doubt in the treatment of your injector that leaks on your Mitsubishi Space star 2, we encourage you to get closer to your mechanic to avoid any bad manipulation that could significantly harm the condition of your Mitsubishi Space star 2.
