So what if you feel as if you have a leaking injector on your Seat Ateca? You almost certainly figured it out thanks to black/oily drips along your engine, or a troubled idle, or abnormal black smoke. These three symptoms are the main indicators of a leaking injector. As this failure can lead to more serious engine complications on your car, we decided to compose this article content to help you verify the failure of a leaking injector and handle it correctly. To do this, we will initially check out the circumstance of gasoline injectors and then at those of diesel injectors Seat Ateca.
Leaking injector on my petrol Seat Ateca
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 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 Seat Ateca: The different leaks
It should be said that injector leaks on a Seat Ateca equipped with a petrol engine are pretty infrequent. 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 component 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 portion 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 Seat Ateca
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure 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 Seat Ateca: The different leaks
In the circumstance of leaking diesel injectors on your Seat Ateca, there are three different sort of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform with time, in most cases the leak will be at the clamping point. - Injector return leakage:
As its name reveals, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Seat Ateca 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 find an air noise and a compression loss. - If after examining you have oil leaking but it does not come from your injectors, we recommend you to consult this article content on the presence of oil leaking on your Seat Ateca.
Leaking injector on my Seat Ateca, how to fix the leak
And at last, we’re going to check out how to fix a leaking injector on your car. Oftentimes a leak is associated, as we have seen prior to this, to a worn seal due to the pressures suffered. But think that the pressure in the circuit is monumental, especially on diesel engines. So you will have to take some measures:
- Lower the pressure before any work is carried out…
- 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 oftentimes be restricted to replacing the seals that have failed:
- Situate the source of the leak
- Dismantle the injector in question
- Replace the corresponding seal kit
- Reassemble the assembly and tighten with a torque wrench in respect with the manufacturer’s standards.
In all situations, these interventions are not specifically very hard, but if you have the tiniest uncertainty in the treatment of your injector that leaks on your Seat Ateca, we recommend you to get closer to your auto mechanic to avoid any bad handling that could significantly harm the condition of your Seat Ateca.
