Under the governor on my farmall regular there is a machined hole in the block which oil drips out of. it looks to be inline with the cam. there is no threads in it like on the cam brass screws.
What is this for and is there a plug of some kind that is suppose to be in there.

i have dozens of pre 39 tractors and pretty much collect mostly them and i dont know what its for at all. doubt you're gonna find an answer
 
It's like this. Inside the block there is a galley bored to oil the front cam bearing. It was bored through from the outside and then plugged. (no room to bore from the inside) I need to go look at a block with the front cover removed to determine exactly how it is fed. You have me curious now. Yes, it was originally plugged with cork. A piece of wood or soft plastic would work too.
 
wtk,
Interesting question. Neat to read the answer. Husband went out to our rusty 1931 regular and scraped the area... sure enough - cork is stuffed in the hole. Would have never noticed it as it was caked-over with 80+ year old grease and dirt. Hmm, learn something every day.
 
I figured it out. The hole on the inside leads to a little trough on the front of the block that oils the front cam bearing by splash.
 
so the hole has no use after its been bored. so the #1 cylinder oils the cam bearing?
 
Right. The hole is bored through then plugged on the outside. Oil comes from the crankcase by splash and is deflected into the inside hole which is open.
 
That's pretty cool.
I know mine was getting oiled because oil was coming out of it.
I got a cork plug at the local Farm and Home and fixed it right up..
