I have not changed an oil pan on a 6.9 yet, but on other vehicles it is possible to change it by only loosening the motor mounts and raising the engine off the frame. Sure does sound like alot work to pull an engine to change the oil pan. just my 2 cents
When you look at how close the cross member is and how big the oil pan is.....
If you loosen the motor mounts and raise the engine as far as you can and block it solid.
Then drop the pan on the cross member and remove the oil pump pickup tube, you are supposed to be able to get it out.
I have never tried it that way, but have read that it can be done.
If you are a decent wrench and have a helper, you can pull the engine out and turn around and put it right back in, around 9 hours time.
So I would put pulling the engine and changing the oil pan at 10 hours.
Thats what I did when I went to put an oil cooler on, couldn't figure out how to get it out in the truck, decided it was easier so I unbolted it, and brought it all the way out, stuck the oil cooler on, took about 9 hours.

Sound right to you Dave?
Yup, but it might take longer for some one that hasn't done it before. Having an automatic could also add an hour because of lines and torque converter bolts to deal with.
I would prefer to just pull the engine for lots of reasons.
For one thing working on my chest bent over is not usually very comfortable and I say that as some one in my early 20s. Also having 1000+ lbs of engine over my arms and maybe head while working isn't a nice thought either.
But have a look at this:
That oil pump has to drop before you can remove the pan. Now I guess the job can be done without disturbing the oil pump and pick up tube, but I'm trying to picture how some one could do a good job cleaning the gasket surfaces to get a seal thats going to last properly. By the book, the gasket should be RTV sealer, but I used the cork gasket that came with my engine kit (then used RTV).
I had a bit of an advantage because our shop has an overhead chain hoist that I used to raise and lower the engine, this allowed me to leave the front clip in place and roll the truck out from under the hoist rather easily.
It could probably be done without pulling the engine, but it really depends on what kind of equipment you have at your disposal and to give the new gasket the best chance I would prefer to pull the engine. That way you know you won't have to do it again any time soon.
I have excellent equipment. 3 ton hoist on a large steel beam. My truck is a manual so no problems with the tranny.
It is a 4x4 if that makes a difference.

p.s. Is that cork gasket any good. Thats what they sold me.
If you have an overhead hoist thats high enough, than pull the engine. When I dropped mine back in, it was really easy, just strait down and then strait back, didn't even have to turn it in either direction. The cork gasket seemed to work fine with mine. My engine has been on the road for about 6 months since I rebuilt it and none of the gaskets are leaking. I used permatex ultra black gasket maker on both sides of the pan gasket when I assembled it and so far, so good. The main thing is to make sure the surfaces are clean before reassembly.
Mine was a 2wd, but it shouldn't make much difference if its 4wd, Dave Sponaugle's trucj is 4wd so I don't see a problem. A universal joint for a 1/2" drive socket helps when reaching the engine mounts from underneath.
I pulled the entire body (cab/front clip) all as one unit and I think it ended up saving me time. It was on a '93 that was pretty rusty. Pull the radiator, disconnect steering, brakes, wiring, and shift linkage and you're in business. The most difficult part was unbolting the six body mounts. They were pretty much shot anyway - and they needed replacing anyway. Saved me the aggrivation of messing with disconnecting the exhaust and drivetrain.
