Leaking injector on my petrol Maserati Levante
It is vital to know that the injectors on petrol and diesel engines are different, the reality is, the difference in combustion between these two sort of engines makes the injection different. 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 Maserati Levante: The different leaks
It should be said that injector leaks on a Maserati Levante equipped with a petrol engine are pretty rare. 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 conceivable that you have a leak from the top of the injector, this is the portion 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 part of the injector of your car, this one will come from the junction with the engine and not with the rail as seen before.
Leaking injector on my diesel Maserati Levante
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 Maserati Levante: The different leaks
In the circumstance of leaking diesel injectors on your Maserati Levante, there are three several sort of leaks:
- Leakage from the injector inlet:
In this instance, it is an inlet pipe that will deform in the long run, usually 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 Maserati Levante will be a consequence of 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 experience an air noise and a compression loss. - If after checking you have oil leaking but it does not come from your injectors, we recommend you to read this content on the existence of oil leaking on your Maserati Levante.
Leaking injector on my Maserati Levante, how to fix the leak
And at last, we’re going to take a look at how to fix a leaking injector on your car. Very often a leak is connected, as we have seen prior to this, to a worn seal caused by the pressures suffered. But think that the pressure in the circuit is tremendous, especially on diesel engines. So you will have to take some precautions:
- Lower the pressure before any work is conducted…
- Covering 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 very often be restricted to swapping the seals that have failed:
- Find out 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 situations, these interventions are not automatically complicated, but if you have the tiniest doubt in the treatment of your injector that leaks on your Maserati Levante, we recommend you to get closer to your mechanic to avoid any bad handling that could significantly harm the condition of your Maserati Levante.
