So I'm changing all my gaskets out in my engine in hopes to reduce the amount of scum accruing on my engine (while at the same time, I'm upgrading to an offy and headers

).
anyway, so I was taking the front cover (I think thats what it is) off. According to my manual, I am supposed to take the oil pump off. I unbolted the oil pump, but it all fell apart. there was a little X thing inside of it that looks like it is supposed to spin, and it turns out the distributor attaches to the other side of it. Anyway, I figured I just screwed myself by taking that off. Can anyone help me put it back together? The manual says to line up the knotches in it, and I do, but it looks like they can line up a number of ways. Then, I'm also not sure which way my distributor was supposed to point...
The good news, is I did set the engine to TDC, so if anyone has any advice, I'd greatly appriciate it. This is my first time I've ever pulled an engine, so it's a learning experience.
