Just got back from the family farm where I spent two days driving the ole 1950 Case model D tractor. Pulled the disc/harrow and cut up massive weeds and vines. In that two day period, Mighty D drank 10 quarts of oil (20W50). When I stopped for lunch today and let the tractor idle before shutting it down, it was smoking so bad, you could hardly see the tractor. Had to remove the spark plugs and clean them twice, (burned them clean with a blowtorch). Even so, oil pressure read a steady 30 pounds the entire time.
Tractor drank 10 quarts of oil - YIKES

Sounds like the rings are cooked.
Do the compression test twice, the second time with some squirts of 20-50 oil into the chambers.
Note the difference.
Do we have 60 years between engine overhauls ?
I think that the oil control rings have lost their spring tension.

I think he said Rebuild parts were not availablle. Id stilll pull it down and take the old rings to napa and match them up to something. Maybe cut it down to a qt or 2 a day lol.
Try a straight weight oil.

These motors are rather easy to rebuild (if you have the parts) as they have wet sleeves. To rebuild, you simply pull the old sleeves and replace them as well as the pistons and rings. You can literally do it in less than a day. The problem however is that they stopped making parts for these tractors in 1980 and now the only parts available are "new old stock" which is getting harder and harder to find and when you do find it, is very expensive.
I do have another "D" that I've been using for parts over the past ten years. I do have an idea on pulling the pistons and sleeves from this tractor and putting two of them on "Mighty 'D'" - but that will be a different post.
In addition, I have inherited a 1947 Case "D" that I need to start working on. It might be time to put "Mighty 'D'" out to pasture and see what this '47 will do - Kinda breaks my heart as I've been driving "Mighty 'D'" since I was five years old - that's 45 years on the same tractor - with that many years it goes from a piece of machinery to an old trusted friend.

Or maybe you could use that copper spray on what you've got?
Is there a way to drop the crank and pistons out the bottom without locking the rings in some sort of sleeve-related purgatory?

No, I haven't heard of them before - will definitely check them out!!! Thanks for the link!

It sounds crazy, but I'd buy and put a good amount of 'Restore' oil additive into a fill of straight 50-weight oil and see how it does.
I've read some darn impressive accounts of Restore 'sealing up' old engine enough that they live to fight another day.
Seriously, give it a try!

How much would you add? It's a four cylinder motor with an eight quart system.
