The breather on the side of the rocker cover needs to have the hole pointed up, and there should be a Brillo pad looking element inside the breather cap. There is a small hole in the side of the rocker cover that I believe is to allow oil in the breather to run back inside the engine rather than down the outside of it.
If you install the breather cap with the hole pointed down, it will make quite a mess on the side of the engine. How do you suppose I know that?!!
All engines produce some blow-by. Worn engines produce more than new engines. With the Ford 4 cylinder diesel, that excess pressure is supposed to go through the pushrod holes through the cylinder head to exit through the breather. I would wonder if your engine is all sludged up, not allowing the blow-by vapor to go from the crankcase through the head and out the breather like it should. If you have not changed the oil yet, that would be the first thing to try. You also might want to remove a side cover, to see if there is sludge buildup around the lifters, and maybe remove the rocker cover to see what that area looks like. You will probably need new gaskets for anything you remove, so I suggest getting them beforehand.
When I got my 641D, it was slobbering oil droplets through the exhaust pretty bad and leaking oil from the rocker cover. I replaced the rocker cover gasket (no sludge at all), and that fixed a lot of the oil leaking, but the droplets kept getting me and the tractor messy.
Finally I needed to do some plowing. I worked the tractor very hard for several hours, causing it to get fairly hot. It popped many chunks of hard material out of the exhaust, some of them red hot, which would have been dangerous if it had been in the dry part of the year. But working the tractor hard for a couple of hours seemed to cause it to work MUCH better. I would guess that it "blew the carbon" out of the exhaust system and made it breathe much better. No more oil droplets from the exhaust. Working the tractor hard also seemed to reduce the amount of blow-by.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
