1984 300SD ATF level drops when cooled ??

According to the manual, the ATF level should be 5 mm below the low mark on dipstick when at air temperature. I imaging this is because hydraulic fluids expand when heated and contract when cooled. I have the opposite: my level is at the full mark at operating temp, then rises about 2 inches over full mark after it sits overnight. It's as if the torque converter is draining into the pan overnight. The transmission is fine and doesn't leak.

Anyone have any thoughts on this? Thanx.

91 350SDL -- HELP - dropped something into engine

This is a new car to me and I was replacing the glow plugs. To make it easier I removed the Intake Manifold on that engine since some of them did not have the 'proper' nuts on the bad glow plugs.

My mistake was to not cover the intake holes and I think something fell into....ALL THE WAY into the cylinder (past the valve). I have all the nuts and bolts that I was using, so I can't figure out what fell in. After I put it together I heard a metallic bang, bang, bang when I started the engine so I shut it down right a way.
