ford 850 oil no pressure

If you have at least some oil pressure you shouldn't cause any more damage by moving it. Rule of thumb is 10 lbs of oil pressure per 1000 rpm. Red exhaust probably has to do with unburnt gasoline from trying to start or the mixture is finishing burning in the exhaust. Try advancing the ignition some more. Higher compression makes more hp.

10 psi should be fine just to drive to the barn as noted by pmsmechanic.

Check your tail pipe. We when doing clean up work pushing backwards would bent the tail pipe causing a restriction.

With a barn to work in just to re ring it would not cost much.

we were always told 6psi per 1k rpms minimums for testing.. etc.

as for the red exhaust. check for lean.. then retarded timing.

them engines should make 40-60 psi cold throttle.

hp increase thru comp ratio and a bigger carb...

no answer so I left it where it was and pulled the pan and oil pump. I took off the middle main bearing cap. The bearing cam of with it. I took 2 photos of that. I pulled the front cap the bearing stayed on . I took a photo of that. In the 1st photo of the front bearing that stayed up. If you look at the bottom left you can see 3/4 inch of metal foil that was being forced out. The next 2 of the middle bearing shows it pretty messed up. Ok I trying to up load the photos but its saying their too large?

This tractor sat for over a year. Ever drop of oil in it seeped down to the pan. They took it home and got it to run on and off. it may of ran 10 or more minutes I think more than that. It ran that long with 0 lubrication. Dry metal against metal. With all the moving parts that need to be oiled when running. I think it is safe to say this motor is toast? I am guessing it not even rebuild able? I need to look for another motor? Would like to hear the experts thoughts.

I sorry if my post are not very clear or making much sense. I think I was in denial mode. I had even bought wire and switches for this before I dropped the pan. I am little depressed I bought this hog thinking it just needed carb rebuilding or something along that line. I never thought I was going to end up with a dead motor. I am just a barn yard mechanic I put in short blocks and stuff like that. But no serious internal engine work. My crawlers are all diesel. I never had serious engine problems. They are mostly frame, track. clutches and welding work. I had to do a lot of my own fabrication on them . This has left me wondering what direction to go. I have no crank, valve, bearing or hardly any internal engine experience or knowledge. No they did not seize the motor but they did run it at least 10 to 15 minutes total. What do you engine guys think I should do next. Can you just clean up the bottom and put on new bearing or what ever? I hate to sound stupid. My line of thinking is that if you run a motor that period of time with out any lubrication. You have ruined it. Is there some thing I can do with this motor ? Should I play with this block any more? Look around for another engine ?
