"ifs" injectors???

[hayjayhorses]

I just pulled a valve cover on my father '99 F450. 3 of the injectors have
" ifs " on the solenoid. I searched for it on line but I got nothing. Dose anyone know who or what ifs is?

Must be the initials from the company that re-maned them.

Don't know who though.

Yeah must be, this truck had a #7 cylinder balance/fault, so I pulled the injector and I took the solenoid off and the armiture plate was loose. So I tightened the screw up reinstalled the injector now the truck runs fine.

The lesson leared?? Pull the solenoid before removing the injector.

WOW.......Those things are pretty darn tight, I am surprised it came loose.

You must have the special tool to tighten that guy, unless that was one of the re-man injectors.

they are remans, it had a T10 torx

do you know what to torque those too.

by the way how is your truck running?

[907DAVE]

Torque them to 70in/lb.

Truck is running great, I am trying to fine tune the turbo's (compounds are confusing), and the tuning (tuning is confusing).
