In the event you are aware of irregular signs on your vehicle, you are right to be intrigued, because a car represents a huge annual budget and sudden malfunctions don’t reduce the costs. So what if you sense that you have a leaking injector on your Kia Forte? You most likely figured it out thanks to black/oily drips along your engine unit, or a disturbed idle, or strange black smoke. These three manifestations are the main indicators of a leaking injector. As this problem can bring on more serious engine trouble on your car, we chose to write this article content to help you ensure the failure of a leaking injector and handle it correctly. To do so, we will first of all check out the case of gasoline injectors and then at those of diesel injectors Kia Forte.
Leaking injector on my petrol Kia Forte
It is essential to know that the injectors on petrol and diesel engines are different, in reality, the difference in combustion between these two sort of engines makes the injection different. The biggest 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 Kia Forte: The different leaks
It should be said that injector leaks on a Kia Forte equipped with a petrol engine are pretty rare. This is due to the much lower pressure in the petrol intake systems. However, 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 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 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 sooner.
Leaking injector on my diesel Kia Forte
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 Kia Forte: The different leaks
In the case of leaking diesel injectors on your Kia Forte, there are three different sort of leaks:
- Leakage from the injector inlet:
In this instance, it is an inlet pipe that will deform along with time, usually 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 Kia Forte 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 recommend you to read this article content on the presence of oil leaking on your Kia Forte.
Leaking injector on my Kia Forte, how to fix the leak
And at last, we’re going to check out 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 suffered. But think that the pressure in the circuit is enormous, especially 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 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 cases, these interventions are not necessarily difficult, but if you have the tiniest uncertainty in the treatment of your injector that leaks on your Kia Forte, we recommend you to get closer to your repair shop to avoid any bad manipulation that could critically harm the condition of your Kia Forte.
