Injector seals leaking
Not quite sure if I should have my injector seals replaced. Passenger side bank appears to be leaking. I’m worried that this could somehow fail and leave me stranded.
Any suggestions?

Thanks.... I have. 2015 F-350 Lariat FX4. The engine is a 6.7 L diesel with 125k miles. Out of warranty. What would you recommend?

The numbers on the injectors is called "IQA". They get this "number" when they are built and tested at the factory that builds them for Ford. The IQA has to do with the flow rating and contribution balance to the 8 cylinders.
When you say the injectors are leaking, is that fuel into the cylinders or fuel onto the valve cover/intake manifold? The injectors are not hydraulic/oil actuated/operated. The injectors are electrical (piezo electric).
Is this mechanic knowledgeable of the 6.7 fuel injection system? There have been very few threads on the 6.7 injectors on FTE. None that I remember about them leaking.
Are the seal leaks where you can photograph it or them?

Don’t know about the 6.7, but I would imagine it’s the same as the 6.4 , the fuel line to the injector has a drag torque and one time use lines. Something to check into.
was there any fuel system work done on this engine?
