[AT] jd 70 diesel tractor

[charlie hill]

well if the oil isn't dripping on the ground or in the water
it's either burning in the engine or possibly leaking through 
into the gear box some how if that is possible with a JD 70?
It wouldn't be possible in the tractors I'm familiar with but 
those crossways 2 cyl JD's are a different sort of animal.

I think I'd call the dealer and tell him what happened and
see how he reacts.  It might be possible to easily fix the 
"leak" but at this point you have to wonder about the bearings
and crank from being run dry.

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?
