In cases where you are aware of irregular symptoms on your vehicle, you are right to be preoccupied, because a car represents a big annual budget and unforeseen malfunctions don’t reduce the costs. So what if you find that you have a leaking injector on your Tesla Model 3? You likely figured it out thanks to black/oily drips along your engine motor, or a disturbed idle, or unusual black smoke. These three manifestations are the main indicators of a leaking injector. As this troubles can end up in more critical engine complications on your car, we thought we would compose this article to help you ensure the failure of a leaking injector and treat it correctly. To do this, we will first look at the circumstance of gasoline injectors and then at those of diesel injectors Tesla Model 3.
Leaking injector on my petrol Tesla Model 3
It is important to know that the injectors on petrol and diesel engines are distinct, in reality, the difference in combustion between these two sort of engines makes the injection distinct. 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 Tesla Model 3: The different leaks
It should be noted that injector leaks on a Tesla Model 3 equipped with a petrol engine are rather 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 possible that you have a leak from the top of the injector, this is the component that is connected 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 occur from the junction with the engine and not with the rail as seen before.
Leaking injector on my diesel Tesla Model 3
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 Tesla Model 3: The different leaks
In the circumstance of leaking diesel injectors on your Tesla Model 3, there are three different sort of leaks:
- Leakage from the injector inlet:
In this instance, it is an inlet pipe that will deform as time passes, usually 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 Tesla Model 3 will be a consequence of 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 examining you have oil leaking but it does not come from your injectors, we recommend you to read this article on the existence of oil leaking on your Tesla Model 3.
Leaking injector on my Tesla Model 3, how to fix the leak
And at last, we’re going to look at how to fix a leaking injector on your car. Very often a leak is linked, as we have seen previously, to a worn seal caused by the pressures suffered. But think that the pressure in the circuit is tremendous, specifically on diesel engines. So you will have to take some measures:
- Lower the pressure before any work is completed…
- 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 very often be restricted to replacing the seals that have failed:
- Locate 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 accordance with the manufacturer’s standards.
In all cases, these interventions are not inevitably complicated, but if you have the slightest hesitation in the treatment of your injector that leaks on your Tesla Model 3, we recommend you to get closer to your auto technician to avoid any bad handling that could seriously harm the condition of your Tesla Model 3.
