Well, I dropped the lower oil pan yesterday. Today, Sunday the rain stopped mid afternoon and I went fishing. Using a telescopic antenna type retriever with a magnet on the end I spent an hour or so pushing it in and pulling it out along the upper oil pan chute. There's nowhere near enough room to get an arm in there. I gave up fishing after an hour or so without a catch. The slot under the camshaft rear pedestal is too tight to get anything that doesn't bend more than an inch or so down. I taped a sliver of a magnet to the end of a yard long curtain spring (that I use for clearing out the sunroof and fender drain tubes)which could be manipulated into the slot and down about a foot or so. I fished for about half an hour and couldn't believe my luck when the shiny side of the fallen nut shone back at me from the flashlight. I hooked a length of baling wire and tried to retrieve it but it dropped off, soddit. I swore loud enough to make some passers by look back. Another ten minutes or so and I was ready for the next catch with more baling wire and the antenna magnet. SUCCESS! First thing I did was put the nut in a magnetic tray on the ground and the second thing was to block off the escape slot before screwing the nut on the valve stem top with clean fingers. I will sleep well tonight.

Can someone let me know why the engine should never be turned counter clockwise, even for a couple of degrees or so?
