Don't have the FSM, but that's good to know TangoFox...
I would guess it's because from the looks of the bolts they come with some sort of loc-tite compound on them.

Pawo, I pretty much torqued every thing down as tight as I could... I've since invested in a torque wrench :/

I decided awhile back that due to some of my metal issues (mostly focus and memory) I wasn't going to work on anything until I managed to get in to a doctor and get a little more stable. The only thing I will do lately is change my own oil and work on things that I can complete in once sitting.. or at least in the same day.
