Looks like it isn't getting any oil.

Tractor had oil pressure. I found these near the broken gear pieces. Clearly not a part of the gear, but no idea where they came from.

cannot tell in the pic what type of material it is, is it bendable with your fingers ? or is it cast ? looks like you still have more broken pieces in the pan, seen a couple broke like this, timing was way off on one and the other the distributor was loose, so in both cases it kicked back breaking gears

Those could be pieces of a connecting rod bearing.

My first thought exactly looking at the material. I have to decide how much effort to put in this thing. There's other big issues. Had to cut a lot of the what little was left of the radiator bolt heads just to get it out

I've seen and dealt with worse. Looks like antifreeze residue in the bolster so that might be a good sign. Wrenching time is a lot more satisfying. than a lot of other things. JMHO Stan
 
This is what was in the bottom of the oil pan. 2 valve keeps, part of the idler gear and a little piece of something unknown.

Any tips for extracting those cut off bolts? Thanks

First, a large quantity of patience! A small set of left hand drill bits will help, sometimes they will back out if you soak them with KROIL/PB Blaster, etc. Try to center punch each one and after tapping moderately with a hammer start with a small diameter bit like 1/8 and step up the size until you reach the threads in the bolster. If you still have any remains of the bolt left, you can remove the remaining debris with a correct size tap. Just don't force the tap and break it off in the hole or you will be back to the starting point. Some medium heat will help break the rust bond also. Another approach is to weld a flat washer to the stub that remains to be removed, then weld a nut to the washer. Heat from the welding will aid in breaking the rust bond also and you can probably remove it with a wrench or vice grips on the nut. Oh yeah, don't forget the patience!!! The pic is of a non runner that sat for about 30 years before I rescued it. JMHO Stan

I absolutely love that hole cut in the hood!
I cut one out of some 6" diameter trees about 20 years ago. Easy fix and a good runner.

I appreciate all the tips on how to get those out! Good stuff.
 
pull the valve cover and see if all the valves are assembled seen the keepers come out if a valve is stuck, make sure they all go up and down
