Have any of you kind gentleman ever posted a how to guide on upgrading the AC system to the refrigerant you can actually buy? (name escapes me) My attempt to fill it with that, with no other work, resulted in a loud bang and oil all over the headers. I have seen on ebay a whole kit to do it, for about 300 bucks but I know you need to flush the system and other things too?

Tried a search on the site; it isn't very good I found.
