Have you changed the oil this year..?

I'm not sure what the original question was, but my Perkins 3-cylinder AD3-152 used to do the same slobbering, black oil thing, until I read the manual, and discovered I was not supposed to warm it up just loping along, gentle, but I was supposed to rev it for 3 minutes at 1200 rpm. I was supposed to operate loaded at 1700 rpm, not just gentle along as easy as I could. Once I began doing that, all the slobbering / wet oil stopped. Never has come back.

When was the last time the tractor was really worked? Setting around at idle and no load can cause a diesel to do that. Many years ago Dad bought an IH 856 that had oil running out the exhaust. Two machine jockey friends had had it and could not sell it because of the way it slobbered over the hood and smoked.We took it to a neighbors farm and put it on a liquid manure pump and worked it hard for a whole day. All the oil burnt up and the smoke quit and the tractor ran great afterward.We sold it and the new owners put several thousand hours on it with no more oil issues. But work is not a fix all for a wore out engine. Tom

FBH44 is right , put her to work on a plow or 16 ft disk and pull the crap out of her for abt a week . She will either dry up or you will know if she needs overhauled . Also a fresh overhaul will wet stack if you just piddle around with her .
