I am definately going to do this in the next couple weeks. So, if no one else writes/photos it, I will.

I don't have any pics because when I did the mod, I didn't have a digicam. Besides, it's so easy even a caveman could do it.

John,

I've been considering doing this mod ever since you mentioned in a thread (couple of years ago?) but I was concerned about maintaining the structural integrity of the cup. I was thinking that since the cup is torqued down fairly tight that the fins do double duty, cooling and strengthening? Did you go in between fins or take out a portion of a fin? Did you go into the side of the cup? NPT threads or straight threads with a crush washer?

So many questions...maybe you could take a pic at your next oil change?

I actually drilled where the fin was, which was right behind the oil fliter bolt, because the hole needs to be about 3/8 or something like that. I don't remember what the exact size was, and I used a 1/8 NPT tap. The material in the bottom of the cup is very thick, check it out next time you change the O ring on the oil filter bolt. I'll bet it's at least 3/8 thick. Plenty of meat to cut the threads in, and with your exhaust, draining the cup will be a breeze. I just used a hex head brass plug, and thread tape on the threads. I just changed the oil before the Pathfinder ride, so it will be a while before I do it again, but if I think of it next time, I'll take some pics.

Sounds easy so I think I will do it next oil change. I have a 1989 Taurus SHO and the 5-speed transmission has no drain plug at all. Yep, if you want to change the tranny oil you have to remove it from the car or else have some special sucker pipe that fits into the fill hole. I did a similar thing on it by drilling into the bottom of the tranny in a certain place then tapping the hole for a brass plug.
