There are two hold down bolts but you only remove the bottom one then you push up on the bracket and it slides out over the top bolt.

Got it! Thanks. I'll warm the truck up and then check them again. Funny thing is the only ones that weren't tight were the ones I suspect of making noise. Maybe it will fix the problem.

Not sure I understand your description.
Did you start off at 50 inch pounds to check if you needed to replace the injector orings, and 6 of them were below 50 before the torque wrench clicked, then you progressed up to 120 or 130 inch pounds? Or were 6 of them below 120?

Sorry. Everything broke at 50. I then moved to 120 and it took under a quarter turn to get the wrench to break. When I ran it before tightening anything there was no oil in fuel filter or coming out of the hole where the injector is. Only out of the spigot. Same as right now. A few weeks ago I ran CCT, rotational velocity, buzz test and checked ICP and IPR values. Everything passed or fell into the normal values. The only thing that was odd was number 8 cylinder but I read that scanners normally read number 8 as something wrong. Is it possible that it's just a noise this truck makes normally and I'm not used to it? I've heard a similar noise in the 6.0 at my work as well as the international 9400i semi we have there.

Alright. I think I'll start putting the covers back on and then finish cleaning some stuff off the engine. I have to drive it tomorrow and get my u joints done this week. I'll see if I can get someone more familiar with the 7.3 than myself to listen and see what he thinks. I could just be over exaggerating a "normal" sound. I don't have the replacement parts on hand to remove the injectors right now but if I do that it should be easier to get everything apart next time around thanks to this experience!

It's all good. I gained experience and learned about the truck. There could still be setting there but I'm going to hope it's nothing that could be catastrophic withing the next couple weeks. What are those mods? Hopefully my seals for the CCV seal up for me. If they don't can I temporarily seal them with a silicone or other non hardening sealant?
