Hi Everyone,
I have a 2.4 Duratorq with the following
CylBal_1 -0.768
CylBal_2 -1.472
CylBal_3 +3.492
CylBal_4 -1.253

DO YOU THINK CYLINDER 3 INJECTOR IS NO GOOD?

Re: Fuel Injector Correction factor TDCI 2.4 Duratorq
The Cylinder Balances (CylBal) indicate how much each cylinder’s injector is compensating for fuel delivery to maintain smooth operation. Ideally, these values should be close to zero, meaning the injectors are delivering fuel evenly. Large deviations suggest potential injector issues.
For your 2.4 Duratorq engine, the high positive value on Cylinder 3 (+3.492) compared to the others suggests that the injector there may be over-fueling to compensate for some imbalance, which could point to an injector issue or potentially a problem within that cylinder itself (like compression loss).
However, before concluding that the injector is faulty, it’s worth investigating other factors:
Compression Test – Ensures there’s no underlying mechanical issue, like low compression.
Injector Test – Testing and/or swapping Cylinder 3’s injector with another to see if the problem follows the injector.
Fuel System Inspection – Ensure no clogs, air leaks, or contaminants in the fuel lines affecting fuel delivery to that injector.
These tests will help confirm if the injector is the root cause. But based on the values, it’s likely that Cylinder 3’s injector could indeed be the culprit.
