I have a 1950 D69U that I’m working on. When I run it oil blows out the exhaust. Any thoughts on what it could be?? Thank you in advance!!

Yeah a good four to eight hour shift at full load would help to clean the 'Slobbering' out. Keep an eye on the temp ... if it don't want to come up to temp check your thermostats are closing all the way. That carbon infused oil I removed with oven cleaner, lye, and drain cleaner and let it set over night at 25ish°F. Then pressure wash with hot water.

These old rigs were made to run. Letting them set for long periods of time is not all that good on them. Things inside get tarnished like the cylinder walls and the rings will most likely lose their seat. One reason for it slobbering is the rings my need reseated. That is why once you get it up to temp you need to reseat the rings by running the puppy water out of it.

worn valves guides can also cause that but most common cause is stuck rings or glazed bores from running at idle or low load too much. diesels need to be worked. dont ring their neck but work em.

whats the oil like? i suggest a oil and filter change and work it. push some dirt around or find something heavy to drag around the yard.

to clean that crud off the exhuast use a product called shock treatment its made by applied chemicals and is part of thier chemtech range of products. it works very well its cuastic soda based so it will strip the fats from skin and burn you so wear gloves.

a hot water pressure cleaner is the bees knees for removing grease and grime. most equipment hire places have them.

what i meant was the oil in the sump. check its condition. but oil and filters are cheap, parts are not so its fairly cheap to simply change it and then you know its got good oil in it.

my thinking when you buy a old machine is check all the fluids if they look okay, get it to start so it runs and moves, no bad noises then good, give it a oil change fresh oil is cheap insurance.

IIRC, Dan, didn't one of your graders put up a slobbery fight during your thermostat trouble? Seems like it took a couple of good exercises before you got it cleared up. I'll agree with the previous statements, get it to temp and put a steady load on it after getting it nice and warm and changing the current oil for a fresh service. JSully, how long has the tractor you're working on been sitting?
