As this problem can bring about more serious engine trouble on your car, we made a decision to produce this content to help you ensure the failure of a leaking injector and handle it correctly.

Leaking injector on my petrol Renault Clio 3
It is important to know that the injectors on petrol and diesel engines are different, the reality is, 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 Renault Clio 3: The different leaks
It should be said that injector leaks on a Renault Clio 3 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 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 connected to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:
At last, you may encounter 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 Renault Clio 3
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 Renault Clio 3: The different leaks
In the circumstance of leaking diesel injectors on your Renault Clio 3, there are three different types of leaks:
- Leakage from the injector inlet:
In cases like this, it is an inlet pipe that will deform in the long run, 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 Renault Clio 3 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 feel an air noise and a compression loss. - If after verifying you have oil leaking but it does not come from your injectors, we encourage you to read this content on the presence of oil leaking on your Renault Clio 3.
Leaking injector on my Renault Clio 3, how to fix the leak
And finally, we’re going to take a look at how to fix a leaking injector on your car. Frequently a leak is linked, as we have seen sooner, to a worn seal because 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 precautions:
- Lower the pressure before any work is conducted…
- Masking you to avoid the risk of fuel spillage
- NEVER work on a running diesel engine injector.
Relating to the repair part of your leak, it will regularly be restricted to replacing the seals that have failed:
- Locate the source of the leak
- Take apart 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 complex, but if you have the smallest hesitation in the treatment of your injector that leaks on your Renault Clio 3, we encourage you to get closer to your auto mechanic to avoid any bad manipulation that could significantly harm the condition of your Renault Clio 3.
