If you are alert of irregular signs on your car, you are right to be intrigued, because a car represents a huge annual budget and unforeseen malfunctions don’t lower the costs. So what if you feel like you have a leaking injector on your Acura TSX? You almost certainly figured it out thanks to black/oily drips along your engine, or a disturbed idle, or unconventional black smoke. These three signs of illness are the main indicators of a leaking injector. As this troubles can produce more serious engine complications on your car, we chose to publish this content page to help you ensure the failure of a leaking injector and handle it properly. To achieve this, we will first look at the case of gasoline injectors and then at those of diesel injectors Acura TSX.
Leaking injector on my petrol Acura TSX
It is important to know that the injectors on petrol and diesel engines are distinct, the truth 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 Acura TSX: The different leaks
It should be said that injector leaks on a Acura TSX equipped with a petrol engine are rather infrequent. This is as a result of 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 plausible 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:
At last, you may suffer a leak coming from the lower portion of the injector of your car, this one will occur from the junction with the engine and not with the rail as seen sooner.
Leaking injector on my diesel Acura TSX
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 Acura TSX: The different leaks
In the case of leaking diesel injectors on your Acura TSX, there are three several 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 implies, this leakage concerns the management of the fuel return in the injector, this time the injector that leaks on your Acura TSX 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 troublesome, 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 content page on the existence of oil leaking on your Acura TSX.
Leaking injector on my Acura TSX, how to fix the leak
And at last, we’re going to look at how to fix a leaking injector on your car. Frequently a leak is associated, as we have seen sooner, to a worn seal due to the pressures endured. 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…
- Masking you to avoid the risk of fuel spillage
- NEVER work on a running diesel engine injector.
Concerning the repair part of your leak, it will oftentimes be restricted to replacing the seals that have failed:
- Identify the source of the leak
- Take apart the injector in question
- Replace 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 complicated, but if you have the tiniest doubt in the treatment of your injector that leaks on your Acura TSX, we suggest you to get closer to your repair shop to avoid any bad handling that could seriously harm the condition of your Acura TSX.
