[AT] jd 70 diesel tractor

No experience with those Deeres but I'm suspecting the same thing. Doesn't 
sound well as far as the bearings go.

No real ideas, but loosing that much oil so fast is a big problem, there's 
really very few places it could go, unless it was burning the oil like fuel 
(which should have also been obvious).  I wonder if there was anyway the oil 
from the crank case could be escaping into the differential housing?  I'm 
surprised he didn't burn out the bearings without any oil.

Enjoy, Joe

Yesterday my brother bought a John Deere 70 diesel tractor with pony
start. He drove it home the 4 miles while I followed. When I drove up he
was putting it in the shed. It didn't quite sound right to me but I
thought it might be the different sound caused by being under the roof.
Then he said that most of the trip it didn't have any oil pressure but
he thought the gauges didn't work. I said that that type of gauge almost
never gave trouble; copper tube to the gauge, not electrical. We checked
the oil level and it appeared empty; not good. We put in 5 or so quarts
to the full mark and restarted the engine. The oil pressure rose right
to the top but soon started to drop and within less than 2 minutes was
back to zero.  We shut it off and checked the oil again; it was
completely empty with no sign of where it went. I thought maybe we
should try more oil again, but by this time my brother wanted nothing to
do with it. He did call a guy in the 2 cylinder club who is considered
to be knowledgeable and all he could think of was a cracked block;
however there appears to be no oil in the water or water in the oil.
What puzzles me is where could 5 quarts of oil go to in less than 2
minutes? Also, it sounds like it is not firing on both cylinders and has
another funny sound like a leaking valve. Over two days when he was
looking at it they started it at least 6 times and drove it back and
forth and it ran perfect. The reason for starting it so much was that
earlier a young guy who said he knew all about these tractors had tried
to start it without the dealer present. Well, he turned the dash mounted
fuel valve the wrong way and turned it so tight that when he went to
turn it back it twisted off the valve.  In the process of fixing the
valve some dirt must have gotten in and the pony motor wasn't getting
enough gas to run right. After getting the gas problem fixed they
started the tractor several times to make sure it was alright. As I
said, at that time it started and ran perfect. It has good paint, good
tires,wide front,power steering but no 3 pt. The person that traded it
said on the phone the the only thing wrong when traded was a small leak
in a steel hydraulic line, which we had already noticed. The dealer said
he always stands behind what he sells, but he did put "as is" on the
bill so we wouldn't go there at this time. It seemed like a good
tractor, but with this problem it's worthless. Any ideas from the list?
