You gotta get the pan and pickup screen cleaned out also so yeah either drop the pan or fill the engine with diesel, soak and drain. or better yet soak and then drop the pan. Last thing you want is your pickup screen clogged. Installing and oil pressure gauge is not a bad idea either.

Actually, the Jeep has an oil pressure gauge. I've kept an eye on it while driving (before pulling the valve cover), and pressure ran from 30 to 80 (depending on throttle, etc).
If I do pour in diesel, how long should I allow it to soak?

overnight with the caveat to keep an eye on the oil pressure in case the screen gets clogged, Also realize that all this cleaning could end up being the last nail in the coffin.

Why do you say that??
I am no expert on the matter but I have read enough threads on this forum to see people doing similar things that you are and to start having problems arise (buy car, see sludge on top, start cleaning heavily, start hearing noises from engine that were not present before, ....some people never post back the results). If I was in your shoes I would not use any cleaning products. I would be to worried that too much sludge gets dislodged and kills the engine. I would remove as much as I could by hand from the top, fill it with a cheap synthetic, and change it often. The only way I would use all those cleaning products is if I was willing to take apart the engine and clean it by hand. I would rather let the oil slowly but surely clean the sludge out, that way the filter and oil can take the excess and not cause a chunk of it to break off and starve a part of the engine from oil.

I certainly appreciate your concerns, and I understand what you are saying. I guess that's why people are recommending Marvel's or Auto RX, which should help to break down the stuff over time. I guess my biggest issue is simply deciding on what to do, and deciding which advice to take.
This experiment in cleaning and all is the best yet,,u got pics and a sequence of events that is outstanding,,real world data is great, not some hype of made up what ifs. I do hope this engine runs and comes back to life for u. U should post the pics in the MMO forum, they would really appreciate ur using MMO, they may come over and help u. Good luck, cant wait to see the finished product,, yep real world data is the best...........sky

that head should come off,and soaked like mentioned before.and check out the bottom end as well.

Ignorance is BLISS!
Yep, basically what I did on the '79 Malibu V6 I mentioned some posts back that was nasty on the top(I did verify the pan was clean)... With normal 3-4K mi oil changes it ran for over seven years without issue, no additives used...
If you can rent a bore scope, you can examine the internal oil pan condition without removing it... Some vehicles are almost impossible to remove the pan without pulling the engine...

OP,
This might be a stretch but I would personally attack it with strong, commonly available solvents.
Take apart as much of the engine as you can reasonably handle and soak it overnight in a couple gallons of solvent.
I personally recommend soaking a few gallons of chlorinated solvent (i.e. CH2Cl2, CHCl3 if you can get it) overnight or for a few days. If you can't get chlorinated solvent, xylene and limonene are also great alternatives.
Limonene would be sweet IMO, you would have a pristine, clean engine that smells extremely strongly of fresh oranges.

alot of good advise in here
i would say pull the oter valve cover also and clean that side then pull the pan clean and flush with a solvent from the head to the crankcase. to remove loose particles.
soaking would be a good idea, id fill it up(reassembled) all the way til it runs out the valve covers and let it sit a couple days.
go with the oil changes and flushes
dont spend too much money your prolly gonna take out some bearings if you dont get all the hard stuff out.

another idea
remove all valvecovers intake timing chain cover and oil pan
spray down with superclean from walmart
let sit 1 hr
wash out top bottom and front with water hose
blow dry with compressed air
repeat if not extremely clean
spray with oil or something to prevent rust
reassemble
add oil and filter with seafoam or mmo
turn engine over without plug wires attached to prime
put wires back on
run 30 mins while watching oil pressure
change oil and filter again
then run a good oil with low oci

Getting lost in this thread any more updates from the OP??
Well, I feel like I made some progress today. I pulled the oil pan, which isn't as simple as I originally thought it would be. Its not a matter of simply removing all 326 bolts (actually closer to 18) to drop the oil pan. Nope, you have to remove the starter and flywheel dust cover, then you can remove the pan.
Here's a pic of the pan:
As you can see, it had some gunk in it as well. I soaked it in diesel fuel, then pressure washed it with hot water and degreaser solution.
Here's the oil screen:
Here's a couple of pics of the crankcase. Please note that these pics were taken while I was laying on a creeper, and you are effectively looking up at the bottom of the engine.
And finally, a pic of the valve cover with new gasket (which is what I initially set out to do):

Wow what a mess! but at least your trying,,good job thanks for the pics you gota long road ahead of you.
was that PU screen that clean or did you clean it?

I went ahead and replaced the thermostat and gasket, and put everything back together. I filled it up with 4 quarts Pennzoil 5w30 and 1 quart of MMO. It has a nice fresh Purolater Gold filter in place, and I drove it around for around 25 miles today. It actually runs and sounds the same, with no discernible difference. I watched the oil pressure gauge, and it stayed at its normal 30-80 (depending on throttle position). The temp gauge also stayed normal, but I honestly didn't expect any real change there.
Its going to take some effort, but I'm going to do my best to drive it as much as possible. Anyone who owns an older Jeep knows these things are short on creature comforts, especially when you are accustomed to driving newer vehicles. I do know it has a small exhaust leak on the top of the pipe, but I am not sure I can get to it with my MIG welder to fix. Guess I'll check on some temporary solutions tomorrow, but it needs to be plugged. Its simply too loud as it is!
