Leaking injector on my petrol Ford Crown Victoria

It is crucial to know that the injectors on petrol and diesel engines are distinct, in reality, the difference in combustion between these two kind of engines makes the injection distinct. The key 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 Ford Crown Victoria: The different leaks

It should be noted that injector leaks on a Ford Crown Victoria equipped with a petrol engine are pretty infrequent. This is resulting from the much lower pressure in the petrol intake systems. However, there are two kind 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.

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 Ford Crown Victoria: The different leaks

Leaking injector on my Ford Crown Victoria, how to fix the leak

But think that the pressure in the circuit is gigantic, especially on diesel engines. So you will have to take some precautions:

  • Lower the pressure before any work is achieved…
  • 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 frequently be restricted to swapping the seals that have failed:

  • Find the source of the leak
  • Take apart the injector in question
