52 H

Hi Guys, I have a 52 Farmall H that I bought out of an old shed. It had sat for at least 10 years. Motor was siezed. I got it loose and the initial compression tests on 2,3,& 4 were 140-145. #1 was 110lbs. After all the various concoctions and soaking the compression is now 140-145lbs on all cyclinders. Oil presure stays between 55-65lbs. It starts and runs really good has lots of power and will run a 7" shredder in knee high grass with little effort. I have skidded 5-6 logs and it lugged down,lost traction, and just spun the tires. It never did kill the motor. The motor smokes and uses a quart of oil in 3-4 hours. About all I have ever done was some shredding and riding around. Until tonight!! I hooked on to my hay rack and hauled 20 people around to look at Christmas lights in our subdivision. We had a great time till we got back to the parking lot at the grocery store and realized everybody was covered in oil spots. Apparently this motor is spraying oil out the exhaust. I ran my finger around the muffler exit and it has about an 1/8" layer of grease in it. Looks like I need to get into the motor. The way it runs I sure wouldn"t think it needs a major overhaul. Please express some opinions on whether I can just put some new rings in? It has stepped head pistons in it, do you suppose that the engine was rebuilt and the valve guides have never been replaced? Can you have that kind of compression and still have bad rings? Thanks in advance.

oil control rings are stuck to the piston after sitting that long. you can try sea foam by adding it to the gas and oil. if that does not work then youll have to do a hone and re-ring.

The best stuff I've ever used is the Top End Engine Cleaner from GM. Saved lots and lots of engines with that mixture.

The rings are 'probably' gobbed up with carbon, rust and crap. Soak it for a couple of days per directions on the can and then work the livin' snot out of 'er for a week.

If this doesn't cure it, ya need an overhaul and you've found out why it was parked to begin with. :>)

I agree with the others - oil rings are stuck. As Allan says, good chance you can free them up with proper treatment. In my Evinrude - Johnson dealership days, the additive was called OMC Engine Tuner. Sprayed it into the carb while running, then into the cylinders after shut-down, let it soak for a few hours and then start it up.
Spin it over for several seconds with the switch off to get oil back onto the cylinder walls before starting.

If it were mine, i would take 3 cans of seafoam, put one can in the oil, one can in the gas. Work the tractor some, put it through various loads. Then at the end of the day do not shut the tractor off, insted slowly pour the remaining can into the carb intake. This will get rid of all of your carbon and will make your tractor smoke heavily, i mean pouring out white smoke. do this with about half of the can, then with the last half, pour into the intake rapidly to get it to stall the engine out.


You can either let it cool down, then come back to start it

Or let it sit overnight

You should be in the hole 35$ after this

If that doesnt stop the burning of the oil you will have to remove the oil pan, take the pistons out take the head off and hone the cylinders and put new rings on, Not that big of a job
