Rough Idle after overhaul of timing chains, phasers, etc.

spray (carefully) some carb cleaner on suspect area. If the running condition changes then you have a leak in that area

Do you have a smoke machine? How did you blow smoke in it (just curious)

I tried the carb spray on all the hoses first and for the back one I sprayed the firewall to get as much back there as possible.

I used a Dutch Master and my lungs, not real scientific but I think it should have been enough.

Gentlemen, thanks for your help. In frustration I took the Expy to the Ford dealer where they found I had a cracked spark plug of all things! Yes it cost me $200+ but no telling how long or what I would have torn apart before finding that.

You could've avoided all that but doesn't matter now truck is running so props to you brotha

I had the exact same issue after doing my cam phasers and drove myself crazy trying to figure it out. After 2 weeks and rechecking everything, my passenger side timing chain was off by one tooth. These motors are hard to time just right. Once I corrected the timing, it was unbelievable how smooth it ran.

Very Nerve Racking experience, I was really stressed and nervous the day I did the actual chain and sprocket replacement for fear of what happened to you.

I agree, and I'm quite sure its my imagination, but Man, It really seems to accelerate faster and have more power after this repair! I am back in love after saying some really bad things about it.

I said so much bad crap about my expy before doing my timing set and after... And I still stand by all that was said, ford made a POS and called it an expedition!

it was either this or buy an over priced "Crack Head" Chevy. I don't do foreign.
