I checked my upper oil pan bolts last night and I was actually surprised to see ALL bolts still in place! Still, I removed the three bolts around the oil pickup tube and Loctite'ed them and retorqued them, then retorqued (without Loctite) the remaining bolts. I probably should have removed and Loctite'ed all of the bolts, but it was very late and I was bone tired and just wanted to finish. Plus I figured that if the bolts have stayed in for 166k+ miles, they would probably be fine.
Also replaced the valve cover breather hose and the hood strut. Next in line:
