Sounds good so far. I'm trying to think of a potential mouse route under the valve covers and am coming up short. Obviously the mice didn't.
On my 20-35 the mice got in the exhaust manifold and set up camp in those generous exhaust ports. Their urine ran into one cylinder and stuck it and also did a number on the valve heads. You might want to drop the exhaust manifold and take a look. I saw at the auction that the previous owner had already started to remove it.

If you look at the 4th picture in post number 6 you can see the oil filter screen laying on the front of the engine block. Without the screen in the oil pan the mice have a doorway into the crankcase and up to the valve covers.

True Jim except that there's 1 in it. That was a spare. My only thought is that the daughter told dad that the tractor sat in the old barn. Then when they tore the barn down it was moved to the shop there. Kinda wondering if it didn't sit partially apart in barn then was worked on and stuck together by someone else who failed to see the new inhabitants. Maybe putting in new screen and adding oil. Kinda been a brain teaser for me today. Has the later heads on it and they seem nice. 203 F

Tinkered with it again today. Dumped PB blaster down the cylinders. After an hour 1,4 were raining down and 2,3 show wetness and drips. Good sign.. or a tease! Wait and see. May toss in shop for a week to do a further tear down and free up. Maybe!

Had an itch. So I tore the heads off to see just how bad it may be. After the rocker assembly's came off i saw that #3 cylinder had a rather high valve... ?odd! Well when the head came off it all started to make sense. 3 at sum point dropped a valve head and exposed cylinder that had now just received a new punched doorway into the crankcase via piston top. So I am now in need off a few valves and a piston. Oh well! That's how Mickey and Minnie got into valve covers. Couple taps with a hammer and a bar engine was turning over freely. Then I evicted the nest out of the block and upper radiator. Good lube of everything including bearings and a quick hone she now rolls right over. 12 of the 16 valves appear nice....but we will see.

Adam...how much cylinder head carnage did the bouncing valve head cause? Probably needs a seat put in? Glad to hear that the engine turns over again!

Some pictographs would be good....remember misery loves company!

Never posted pics on here not sure how. Yes carnage it did. First clue was broken valve guide piece upon dismantle in intake. Then the valve stem sticking way up after rocker arm tear down. Seat shot...and 1bent valve along with 2 others beat up. May just replace the 4 valves. Rest look very good but may order 2 extras in case pee got to sum. Found a nos piston maybe if part number lines up. Going to get heads done over winter and all the smalls so that in spring I may tackle in just a few days. Ha ha probably wishful thinking. Kinda got side tracked from 250116 with a new toy in the stable. Evicted mice nest from radiator and block. Darn mess.

Kinda would like to find exhaust elbow. I actually need 3. But 2 for sure.

Yep...I hear you with the picture thing. It took me a fair amount of time under the constant direction of my kids before I could finally post photos on here unassisted. If someone messes with the camera settings I'm still at their mercy to get it back on track.

I'm getting pretty good at putting seats in my heads. I finished putting 8 seats in the 1st head and just got it back today after Henry resurfaced it. I still need to load the valves in it. It seems that Henry at H&J Machine loaned me an old KO Lee hand powered seat cutter (never seen one before) and showed me how to use it. He did one and then told me the rest is yours...get after it!
I am installing late JD A exhaust seats which is a pretty close fit. I'll post an update on the other channel some evening.

Did the head come off an intake valve?

When you mention exhaust elbow do you mean the elbow above the heater bypass or the short turnout that is below it?

Below it. A friend is going to help me with the seat though I would like to learn how. Have to get Henry intake up some valves and couple guides. Exhaust valve gave out.
