Leaking injector on my petrol Honda CR V
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 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 Honda CR V: The different leaks
It should be noted that injector leaks on a Honda CR V equipped with a petrol engine are pretty rare. This is resulting from the much lower pressure in the petrol intake systems. However, 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 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 come from the junction with the engine and not with the rail as seen sooner.
Leaking injector on my diesel Honda CR V
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 Honda CR V: The different leaks
In the circumstance of leaking diesel injectors on your Honda CR V, there are three different types of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform in the long run, in most cases the leak will be at the clamping point. - Injector return leakage:
As its name implies, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Honda CR V 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 find an air noise and a compression loss. - If after verifying you have oil leaking but it does not come from your injectors, we recommend you to read this article content on the presence of oil leaking on your Honda CR V.
Leaking injector on my Honda CR V, how to fix the leak
And at last, we’re going to check out how to fix a leaking injector on your car. Regularly a leak is associated, as we have seen previously, to a worn seal caused by 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.
Relating to the repair part of your leak, it will very often be restricted to changing the seals that have failed:
- Situate 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 situations, these interventions are not specifically very hard, but if you have the slightest hesitation in the treatment of your injector that leaks on your Honda CR V, we recommend you to get closer to your repair shop to avoid any bad manipulation that could seriously harm the condition of your Honda CR V.
