I was thinking about this and wondered why can't it be done. Drain and replace the old oil and filter. Add new oil and 1 or 2 quarts of diesel fuel or atf to the mix. Remove the coil wire. Crank engine over for 10 seconds to move the oil mixture around. Let it set for 10 minutes and repeat 2 more times. Then open both drains and pour straight diesel down the dipstick tube to wash out the sediment. Let it drain 30 minutes. Replace oil and filter.

It seems like it would work in theory. Not pumping fast enough to pull gunk into the pick up tubes but just enough to toss the mixture around. Any thoughts?

what makes you think there is a bunch of gunk in there? and if there is I'd leave it alone....disturbing it will start to clog crap up

I think your worrying about this a bit too much. The inside of a motor is much cleaner than the outside. Even motors with minimal maintenance don't have THAT much sludge build up in the crankcase.

Unless your not telling us something lol.

Besides, if you're that worried about gunk in the pan, it's best to do it right...take it off and clean the pan off the car. Diesel fuel can harden some seals so I wouldn't use it.
