I'm not joking ... I don't know how many nuts, bolts and other small tools have gone in never to be seen again. I ended up buying one of those telescopic magnet tools (great $3 investment by the way). I occasionally find tools nad such when I'm working on it. Heck, Nissan left a pack of razorblades and 2 screwdrivers sitting in the engine after working on it once. I was not happy ... at least I lose the tools deep in the engine somewhere. :)
