I have a '72 Ford 3000 Diesel, that was left abandoned until just before I bought it. 6 speed, transmission PTO, power steering, thermostart, no locking differential. Previous owner had the fuel pump and clutch worked on. It starts right up, runs well, but it slobbers. I have read various post about slobber and it needing a hard workout, which I have done. Also put in a 190 degree thermostat. It cleared up but only for a short while. I also noticed that it slobbers much more at high RPM. Could it be a bad injector at this point? Any way to test (don't want to purchase a pressure pump, if I don't have to) Any suggestions?

You need to work it lke a dog for several days to weeks to clean it up. and don't be idling it setting whle loading wood or other putter jobs. Idling is one of the worst things for a diesel. The cylinder temperature drops off even though the gauge says it is up and then fuel gets by the rings washing the cylinders out. This is the reason for seeing fuel dilution in the crankcase when checking oil or at oil changes. If you doubt it do an oil sample test and it will prove it. I've had it on my semi's in the winter with idling for heat. Need to idle them around a 1000 RPM if you are going to idle much. My dad wants to just idle around with the loader and it smokes all the time till we put it on a load like an auger where it runs wide open all the while we are unloading so for about an hour at a time with shut down shortly after.
Could be..... bad exhaust valve guides.. bad injectors, low compression, bad pump timing, leaking head gasket. have you checked the radiator for bubbles and or pressure?
AND condensation building up in the exhaust system will always make a cold engine slobber a bit as it washing out the carbon, but this should... burn off as the engine comes up to temp.

If it's wet stacking, working it for a little bit ONCE is not a permanent cure. The engine needs regular hard work or it will go back to wet stacking.

Give it a treatment of fuel injector cleaner and then as others have said work it hard. I had a B250 that sat for 15 years , it was hard
starting and slobbered. I used injection cleaner and ran it all day raking hay. Within a few days it started easily and the slobbering went
away. I swear by injector cleaner.

I agree. Hook it to a heavy plow and run it hard at PTO RPM for 2 hours for a number. I assume your fuel is fresh. Agree on injector
cleaner or 2 or more Oz. of Sea Foam added to the fuel per gallon. Add a pint of Sea Foam in the 6 qt. oil too.....drain and replace
the oil and filter when finished. Worked for me on my '65 3000.
