With the help of some kerosene, some degreaser, and a power washer, I cleaned up the engine reasonably well, and then drove it around for a while. Most of the engine looks to be dry/leak free, but it looks like there is some fresh oil by the rear main seal.

I know there are a bunch of threads on this, but I see some conflicting info. On my 65 GMC 1000 w/ the L6 230, do I need to unbolt or loosen the engine, and jack it up in order to get the oil pan off? In my GMC Maintenance Manual, the procedure for changing the rear main seal does not include this step.

I'm not looking forward to dropping the pan. It looks like a PO used gorilla glue or some kind of slight expanding foam to seal the pan. The pan has also been dropped and sprayed blue, but the blue is peeling off and I can see the original red beneath it. So Ideally I'll completely remove the pan, clean it, spray red again, and button it back up.
