So what if you think that you have a leaking injector on your Volkswagen California? You likely figured it out thanks to black/oily drips along your engine motor, or a troubled idle, or strange black smoke. These three signs of illness are the main symptoms of a leaking injector. As this problem can bring on more severe engine trouble on your car, we chose to publish this article to help you ensure the failure of a leaking injector and treat it properly. To accomplish this, we will first of all check out the circumstance of gasoline injectors and then at those of diesel injectors Volkswagen California.
Leaking injector on my petrol Volkswagen California
It is crucial to know that the injectors on petrol and diesel engines are different, in fact, the difference in combustion between these two types of engines makes the injection different. 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 Volkswagen California: The different leaks
It should be said that injector leaks on a Volkswagen California equipped with a petrol engine are rather infrequent. This is caused by the much lower pressure in the petrol intake systems. However, there are two types of leaks:
- Leakage from the top of the injector:
It is possible that you have a leak from the top of the injector, this is the component that is attached to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:
Finally, you may encounter 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 Volkswagen California
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 Volkswagen California: The different leaks
In the circumstance of leaking diesel injectors on your Volkswagen California, there are three different types of leaks:
- Leakage from the injector inlet:
In cases like this, it is an inlet pipe that will deform in the long run, commonly 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 Volkswagen California 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 bothersome, 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 checking you have oil leaking but it does not come from your injectors, we suggest you to consult this article on the presence of oil leaking on your Volkswagen California.
Leaking injector on my Volkswagen California, how to fix the leak
And finally, we’re going to check out how to fix a leaking injector on your car. Frequently a leak is linked, as we have seen prior to this, to a worn seal caused by the pressures suffered. But think that the pressure in the circuit is monumental, especially on diesel engines. So you will have to take some safety measures:
- Lower the pressure before any work is achieved…
- 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 replacing the seals that have failed:
- Discover the source of the leak
- Take apart 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 specifically complex, but if you have the tiniest uncertainty in the treatment of your injector that leaks on your Volkswagen California, we suggest you to get closer to your motor mechanic to avoid any bad handling that could severely harm the condition of your Volkswagen California.
