++++ times 10 to the above. Only time I've pulled a Stovebolt oil pan was while chasing and repairing leaks. This experience indicated that for me, it's a day job. First scraping and cleaning the block and pan particularly the flange area of the block and then the pan. Then once the pan's off the cleaning and prepping/painting prior to replacing takes longer than you'll expect. I used a lot of Purple Power cleaner (full strength) and a stiff brush to remove all the old gunk. Also used high pressure water to flush the oil tubes. You'll see what I mean when the pan is on the workbench.
I do like Jerry's trick on adding diesel or kerosene to start and speed the sludge removal process, I'll use that trick somewhere down the road. And as Martin suggested, go for a drive, then get on with the day.
Good Luck, Ron
