Leaking injector on my petrol Skoda Kamiq
It is essential 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 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 Skoda Kamiq: The different leaks
It should be known that injector leaks on a Skoda Kamiq equipped with a petrol engine are pretty infrequent. This is because of the much lower pressure in the petrol intake systems. Even so, 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 component that is linked to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:

Leaking injector on my diesel Skoda Kamiq
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 Skoda Kamiq: The different leaks
In the circumstance of leaking diesel injectors on your Skoda Kamiq, there are three different kind of leaks:
- Leakage from the injector inlet:

This injection leak is one of the most annoying, it is the junction between the engine and the injector nose that leaks at a copper seal, you should encounter an air noise and a compression loss. - If after examining you have oil leaking but it does not come from your injectors, we advise you to read this article content on the existence of oil leaking on your Skoda Kamiq.
Leaking injector on my Skoda Kamiq, how to fix the leak
And to finish, we’re going to look at how to fix a leaking injector on your car. Very often a leak is associated, as we have seen sooner, to a worn seal caused by the pressures endured. 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 conducted…
- 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 frequently be restricted to swapping the seals that have failed:
- Discover 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 inevitably complicated, but if you have the slightest doubt in the treatment of your injector that leaks on your Skoda Kamiq, we advise you to get closer to your auto technician to avoid any bad manipulation that could significantly harm the condition of your Skoda Kamiq.
