Calif. Farmall said: (quoted from post at 13:50:35 05/06/08) I like the plow, mine is just like it but it's got a disc or sod cutter in front. Came off grandpa's cub 30yrs ago (not much good in Los Angeles CA. even 30yrs ago, wouldn't cut in to all the cement down there) and I never did use it. Oh well back to the issue at hand, I did notice as he really started pulling hard no smoke out the pipe but lots out the oil fill. That tells me you are making good compression, the oil rings and valve seals are working. You just aren't getting a good seal on the top rings, enough to make compression but not enough to keep all that pressure in. Drag Race cars have a similar problem at WOT, they run the breather tube into the the header with a smog pump check valve so exhaust wont get into the engine. The exhaust actually sucks all the blow by out and burns it. If it were mine, and I was out of money which I am. I would hook up a PCV valve off a 95 dodge caravan 3.0 engine. They use a 1/8 pipe threads on the intake side and 5/16 vacuum hose nipple on the other side. Hook up a fitting off the side of the valve cover by brazing a nipple on the side and run it to the intake just above the carb. My A has a 1/8 pipe plug already there but you may have to drill a hole. That may suck enough blow by out that you don't notice it. The only other remedy you might try is non detergent oil but it's hard on the bearings. Might try it for a few weeks of work and see what happens. Could be the chrome rings, they really need a good surface to seat into. I try to only use Hastings cast iron, and even then I only have 50% success rate unless the cylinders were replaced or cut oversize and a perfect round surface. The last few times I've been bit by rings not sealing I decided a few years ago to quit doing it without boring or replacing the cylinders. Hope this helps, DAN.
Interesting idea! I might just try this before doing another overhaul.....heck its not like its not performing above par or giving me any trouble so I think I'll just run her as is. I have had the opportunity to try out another fully restored Farmall 100 and pulled a larger set of disks than mine with it and as far as performance mine is on par with his so I guess I'll just let it go and hope that its just the rings not seating. Otherwisre if it gives me any trouble later on I'll pop the head and change the sleeves.
The plow setup is embarassing. Thing is I didn't know it was made for this little tractor and used the drawbar flipped forward to mount. I've been fabbing up the parts for next season. Here is how it's supposed to mount. (Pics and knowledge of this thanks to GeorgeKY :D )

Today's Featured Article - Pitfalls of Tractor Engine Rebuilds - by Chris Pratt. The first pop after you have put the machine together with your own hands is exciting and pleasing. The whole experience can be marred if one moves too fast and makes too many assumptions that they can just use "as is" some parts they should be closely scrutinizing and possibly attended to. In such cases, rework makes what could have been a fun project turn into an irritant or even a nightmare. Minor Irritants To give you an example of an minor but irritating proble
