Heh, bet you learned your lesson about closing your mouth when working under cars! I should make a habit of wearing a light dust mask.
My first engine rebuild was a VW. 275 ft/lb for the 32?mm bolt that held the fly wheel on. At some point the fly wheel slipped and my little finger managed to find a pinch point on the gearing on the fly wheel.
A friend and I did some drunken demolition in my house last year and took out a wall. I was wearing flip flops. He dropped a 2x4 with a nail in it right through the side of my big toe. THUNK. I learned my lesson about that.
In fact the list of non car related accidents I have had is pretty lengthy, I am very careful around cars. Its just a bloody flesh wound!
