I tried something similar to that. I installed an air hose into a bad drain plug, then put in 2 gallons of diesel and turned the oir pressure on low to make the diesel bubble for a few hours. I drained it and repeated this twice more. The diesel was fairly black, but when I pulled the oil pan a week later I still had an inch or thick crud on the bottom.
