I just removed one from an engine that sat outside for a LONG time in humid climate. I use PB Blaster and tapped on the housing ever few days over a period of a month. I finally got the distributor to turn. Once I got it to turn, I used a strap wrench with a rubber strap and worked it back and forth several times. I thin used a 2 X 4 and tapped it on the bottom until it came out. It came out with no apparent damage to the distributor.
