In the event you are alert of irregular symptoms on your car, you are right to be concerned, because a car represents a big annual budget and surprising breakdowns don’t reduce the bill. So what if you find that you have a leaking injector on your Mitsubishi Asx? You likely figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or unusual black smoke. These three manifestations are the main signs of a leaking injector. As this troubles can bring about more critical engine complications on your car, we decided to produce this article content to help you verify the failure of a leaking injector and handle it properly. To achieve this, we will first of all look into the circumstance of gasoline injectors and then at those of diesel injectors Mitsubishi Asx.
Leaking injector on my petrol Mitsubishi Asx
It is important 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 Mitsubishi Asx: The different leaks
It should be noted that injector leaks on a Mitsubishi Asx equipped with a petrol engine are rather infrequent. This is as a result of 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 part 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 experience 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 previously.
Leaking injector on my diesel Mitsubishi Asx
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure 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 Asx: The different leaks
In the circumstance of leaking diesel injectors on your Mitsubishi Asx, there are three different kind of leaks:
- Leakage from the injector inlet:
In cases like this, it is an inlet pipe that will deform over time, in most cases the leak will be at the clamping point. - Injector return leakage:
As its name indicates, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Mitsubishi Asx 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 verifying you have oil leaking but it does not come from your injectors, we suggest you to browse this article content on the presence of oil leaking on your Mitsubishi Asx.
Leaking injector on my Mitsubishi Asx, how to fix the leak
And at last, we’re going to look into how to fix a leaking injector on your car. Regularly a leak is connected, as we have seen sooner, to a worn seal due to the pressures endured. But think that the pressure in the circuit is enormous, specifically 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 frequently be limited to changing the seals that have failed:
- Find out 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 accordance with the manufacturer’s standards.
In all cases, these interventions are not necessarily very hard, but if you have the slightest hesitation in the treatment of your injector that leaks on your Mitsubishi Asx, we suggest you to get closer to your auto technician to avoid any bad handling that could seriously harm the condition of your Mitsubishi Asx.
