So what if you think that you have a leaking injector on your skoda yeti? You likely figured it out thanks to black/oily drips along your engine, or a troubled idle, or abnormal black smoke. These three signs of illness are the main symptoms of a leaking injector. As this problem can cause more severe engine trouble on your car, we decided to compose this article to help you confirm the failure of a leaking injector and handle it properly. To do so, we will initially look into the circumstance of gasoline injectors and then at those of diesel injectors skoda yeti.
Leaking injector on my petrol skoda yeti
It is fundamental to know that the injectors on petrol and diesel engines are different, in reality, 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 skoda yeti: The different leaks
It should be known that injector leaks on a skoda yeti equipped with a petrol engine are pretty rare. This is resulting from the much lower pressure in the petrol intake systems. Nevertheless, there are two types 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 portion that is attached 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 part of the injector of your car, this one will appear from the junction with the engine and not with the rail as seen before.
Leaking injector on my diesel skoda yeti
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 skoda yeti: The different leaks
In the circumstance of leaking diesel injectors on your skoda yeti, there are three different types of leaks:
- Leakage from the injector inlet:
In this instance, it is an inlet pipe that will deform after a while, commonly 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 skoda yeti 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 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 on the existence of oil leaking on your skoda yeti.
Leaking injector on my skoda yeti, how to fix the leak
And to finish, we’re going to look into how to fix a leaking injector on your car. Regularly a leak is associated, as we have seen previously, to a worn seal due to the pressures endured. But think that the pressure in the circuit is monumental, specifically on diesel engines. So you will have to take some safety measures:
- Lower the pressure before any work is achieved…
- 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 very often be restricted to replacing the seals that have failed:
- Find out the source of the leak
- Dismantle the injector in question
- Change 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 automatically difficult, but if you have the slightest hesitation in the treatment of your injector that leaks on your skoda yeti, we recommend you to get closer to your motor mechanic to avoid any bad manipulation that could significantly harm the condition of your skoda yeti.
