Rocker Arm?
Ok so I pulled the driver side VC hoping to see some chaffing loose plug or somthing to identify the problems im having. No such luck. So correct me if im wrong but the arm that is at the end of my connecting rod is the rocker arm, and that arm on a few rods can move side to side a good but. Some were tight with no movement at all, others moved nearly an 1/8 inch side to side. What kind of future damage or current problems could this be causing?

If I found the right one it should be 20 ft lbs
This is where I got it:

I don't even know whether we have solid lifters or hydraulic. With solid is there not some valve lash required? But with hydraulic there would be zero lash and only then would just torqueing them work. I have no business getting involved here......LOL..I don't have a clue how the valve train works as I've never even seen under one of our valve covers. Hope it stays that way. Is there a rocker arm shaft, or is each rocker on its own pivot point?

Each rocker is on a ball bearing with a clip on its own pivot point , there is no adjustment possible that I know of ,just torque the hold down bolt .

Doing mine today as soon as i get my coffee
After some searching around i found a thread with Dan ( kwikordead ) giving us the torque.
20 foot pounds on the rocker pedastals, four bolts per pedastal. (also as jim has stated)
Also check injectors while your there.
120 INCH pounds on the lower bolt holding the injector in.

yea it started getting dark out and i was afraid of rain hitting, so i closed up before i could get to the injectors. That and i usually carry my laptop down to have you guys at close hand if i get lost somwhere and i didnt have it ready either so. But i will be keeping you guys in check this afternoon, im picking up a scanner from my dad to see what the computer says is wrong. Im convinvece that my CEL donest work, never seen it come on and the truck runs like garbage, and no i have a massive powersteering fluid leak. As soon as i pour it in it comes right out, almost of the drivers front wheel. (in the whele well) Anyways off to a baby shower! wahoo! thanks again guys your the best! Steve.

Steve. Keep an eye out where that fluid is going. Your IDM is inside the drivers front fender above the wheel well. If you get water, or any other kind of fluid on the IDM it can cause your truck to run bad.

You can check out Scott's gallery here 2001 Ford F250 4x4 - IDM mod pictorial
This is actually instructions on how to mod the IDM, but it will show you where it is and what it looks like. I don't know of any way to test one, but have heard of a few who could hear water sloshing around inside theirs if they shook it. It's basically wires & circuit boards so it doesn't play well with fluids.

Didnt read much of the thread, but the valves do not get adjusted, the engine oil pressure inside the hydraulic lifters keeps constant valve lash, i'm assuming it's .000" or damn close to it, but it is "soft", only held there by oil pressure. The camshaft pushing on the lifter pushing on the pushrod directly relates to if the valve has tension on it or not. The cylinders not currently on a valve cycle do not have any side to side pressure on the rocker arm.
