It's on permanently for now, that sucks that the drain plug could be located better. Guess I'll have to deal with it. My one complaint with the pan was that the all the bolt holes were off and I had to grind most of them bigger so I could get the pan located. Don't know if there jig was off when they built my particular pan but all my gaskets laid in perfectly so I don't think it's the original block bolt layout that's the problem.
