In the event you are informed of abnormal symptoms on your car, you are right to be worried, because a car represents a massive annual budget and sudden malfunctions don’t lower the expenses. So what if you sense that you have a leaking injector on your Suzuki Alto? You most likely figured it out thanks to black/oily drips along your engine unit, or a disturbed idle, or strange black smoke. These three manifestations are the main symptoms of a leaking injector. As this problem can cause more severe engine complications on your car, we decided to prepare this article content to help you verify the failure of a leaking injector and deal with it correctly. To achieve this, we will initially check out the case of gasoline injectors and then at those of diesel injectors Suzuki Alto.
Leaking injector on my petrol Suzuki Alto
It is important to know that the injectors on petrol and diesel engines are distinct, the reality is, the difference in combustion between these two types of engines makes the injection distinct. 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 Suzuki Alto: The different leaks
It should be mentioned that injector leaks on a Suzuki Alto equipped with a petrol engine are rather rare. This is due to the much lower pressure in the petrol intake systems. Even so, 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 part that is connected 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 appear from the junction with the engine and not with the rail as seen before.
Leaking injector on my diesel Suzuki Alto
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure produces 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 Suzuki Alto: The different leaks
In the case of leaking diesel injectors on your Suzuki Alto, there are three different types of leaks:
- Leakage from the injector inlet:
In this case, it is an inlet pipe that will deform over time, in most cases the leak will be at the clamping point. - Injector return leakage:
As its name indicates, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Suzuki Alto 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 bothersome, it is the junction between the engine and the injector nose that leaks at a copper seal, you should experience an air noise and a compression loss. - If after verifying you have oil leaking but it does not come from your injectors, we suggest you to read this article content on the existence of oil leaking on your Suzuki Alto.
Leaking injector on my Suzuki Alto, how to fix the leak
And finally, we’re going to check out how to fix a leaking injector on your car. Oftentimes a leak is associated, as we have seen sooner, to a worn seal as a result of the pressures endured. But think that the pressure in the circuit is enormous, especially 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 frequently be limited to replacing the seals that have failed:
- Locate the source of the leak
- Take apart the injector in question
- Replace the corresponding seal kit
- Reassemble the assembly and tighten with a torque wrench in accordance with the manufacturer’s standards.
In all situations, these interventions are not necessarily difficult, but if you have the tiniest hesitation in the treatment of your injector that leaks on your Suzuki Alto, we suggest you to get closer to your auto technician to avoid any bad manipulation that could significantly harm the condition of your Suzuki Alto.
