Does Ford recommend replacing...

Does Ford recommend replacing all fuel injectors when an engine is overhauled/replaced? If so, where?

Mechanic's Assistant: Has the vehicle turned into a gas hog? And how does it start -- same as usual?

Let's just say the power balance test did not show any cylinders out of 5% of the average, but the current set had 185K miles on them.

Mechanic's Assistant: What is the model/year of your Ford?

2008 550 with a 6.4L deisel

Mechanic's Assistant: Are you fixing your 550 yourself? What have you tried so far?

No, I really just want to know what Ford's recommendation is and where they published it.

Hi Im David, thanks for visiting the site. There is no recommendation unless the injectors fail a flow test, resistance test or balance test. In other words if its not broke dont fix it.

Thank you for your response. That answers my question. Do you happen to know of any direct written reference from Ford regarding whether the injectors and rails should be replaced during an engine replacement.

I know for a fact there is no reference material to that affect. its just remove and reinstall the rail and injectors.

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey
