If you are aware of irregular signs on your vehicle, you are right to be intrigued, because a car represents a massive annual budget and unexpected breakdowns don’t reduce the costs. So what if you feel like you have a leaking injector on your Honda Odyssey? You almost certainly figured it out thanks to black/oily drips along your engine unit, or a disturbed idle, or abnormal black smoke. These three symptoms are the main symptoms of a leaking injector. As this problem can end up in more severe engine trouble on your car, we decided to produce this article to help you validate the failure of a leaking injector and deal with it properly. To achieve this, we will first check out the circumstance of gasoline injectors and then at those of diesel injectors Honda Odyssey.
Leaking injector on my petrol Honda Odyssey
It is vital 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 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 Honda Odyssey: The different leaks
It should be known that injector leaks on a Honda Odyssey equipped with a petrol engine are rather infrequent. This is resulting from 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 plausible 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 experience a leak coming from the lower portion 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 Odyssey
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion system 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 Honda Odyssey: The different leaks
In the circumstance of leaking diesel injectors on your Honda Odyssey, there are three different kind of leaks:
- Leakage from the injector inlet:
In this instance, 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 indicates, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Honda Odyssey 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 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 encourage you to browse this article on the existence of oil leaking on your Honda Odyssey.
Leaking injector on my Honda Odyssey, how to fix the leak
And to finish, we’re going to check out how to fix a leaking injector on your car. Very often a leak is associated, as we have seen prior to this, to a worn seal due to the pressures endured. But think that the pressure in the circuit is gigantic, 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.
Regarding the repair part of your leak, it will oftentimes be restricted to changing the seals that have failed:
- Identify 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 respect with the manufacturer’s standards.
In all situations, these interventions are not necessarily complicated, but if you have the smallest uncertainty in the treatment of your injector that leaks on your Honda Odyssey, we encourage you to get closer to your repair shop to avoid any bad handling that could significantly harm the condition of your Honda Odyssey.
