While working on the bottom of a motor that's still in the vehicle, it would be a wise idea to wear some sort of goggles. Had to wash oil out of my eye for several minutes. Glasses just don't do the trick when it hits your forehead and then runs into your eye. And now I have a lovely motor oil smell stuck in my nose from the oil mustache. My hands are slowly thawing out now. 33 degrees outside! brrr.
