I pulled my motor apart to and see what I would need for a rebuild and I found this is the oil pan

Looks like a band nut, and the nut and bolt that holds the coilbox to the firewall. The only damage on the mag coils appeared to be on one coil by the starter, probably from an attempt to remove the starter with the bendix still attached.

I also sound that number one piston was installed in the opposite direction of the other 3, but all the rod caps were in the same direction. There are no shims in the rods. I haven't pulled the main caps yet but I also found the cam gear nut was loose about a full turn.
The trans drums look good on the surface. Will get further in to it later this week.

I hate auto correct. It supposed to read inspection

Infection could work too :-) the oil that is still on the crank looks a little "milky" is it really old or could you have a small coolant leak? or is it an optical illusion?

G.R., I was thinking that also. The oil looks to be a bit thick also. I had a 15 engine that had not been run in 40 years and when I pulled the oil plug it took two days for the goo inside to drain!

Good idea to pull it down for a cleaning and a check up :-)
The original rods in an engine didn't have any shims from the factory, only the main bearings had shims. You can file the caps to adjust the rod bearings somewhat before replacement/repouring is necessary (if the babbitt isn't damaged with loose parts or excessive side play). Replacement rods from Ford had shims from start.

Don't think you have a problem with those bits beyond a former owner dropping a few items. Surely the carriage bolt/nut is just visiting & I'm sure the band nut is there for the same reason. First it's "Oh s**t" then it's "Oh well". I'm familiar with that goop too. With my '23 I dropped the plug & nothing came out until I poked it a bit. It was a little disheartening seeing that goop but it turned out OK.

The problem with filing the caps is that if you ever want to install a new crankshaft with standard bearings, there might not be enough space left for the babbit.

It looks like the oil has water or coolant mixed in with the oil.

That's Really some Nasty looking oil!!

Don't worry about the extra parts if they didn't do any harm already they won't Now.

Norman, don't fret about filing the caps too much. Each adjustment should only take a couple of thou, and you can do a lot of such adjustments before the caps are rendered useless.
