Ding Ding Ding, MoparforLife got it right (at least for now). At one point I had the 90 degree adapter on, and when I took it off, the small steel covered gasket must have stuck to the block, cause sure enough, it was still there.

So I cleaned it up and put on a new outer gasket, no leak now! Let's hope it stays that way.

Thanks for all the help guys, I appreciate it. Now i have to enter a new post about my newest issue!
