Anti-freeze in oil

[Notsofastfreddie]

I have a 1959 mf 65 gas tractor with anti-freeze in the oil pan. Just got the tractor, with no history on it. Compression chk on cylinders is 150 for the front 3, 135 for back one, leaked down 30 lbs in 10 minutes. Is there a way to isolate the leak prior to tearing engine apart? If the block is cracked, is it repairable? The engine did start and run ok, just lots of bearing noise. Thank you for any help you can offer, Fred

Not sure if it is a wet sleeve engine or not but if it is one thing to do is pull the oil pan and see if you can see coolant leaking at the sleeve seals. You can also do that to see if it is coming from around one of the piston as in a head gasket leak

if you have a tractor with antifreeze in oil and lots of brg. noises, engine is not ok and that is a complete engine tear down job and is worth more than the tractor.

I have had really good luck with irontite. My das 270 leyland responded well to a treatment a year ago. It had leaky liner seals.

Even if you are able to correct the crack, the engine sounds like it will need rebuilding. I would remove the head, clean both the head and block mating surface as clean as you can get them. I use a Scotchbrit pad and a a high speed rotory tool to get all debris off the surface. Then I use a three part dye penetrant spray to find the crack. Depending on the crack, it may be repairable. If so, I'ld probably repair it and rebuild the engine, but it's up to you. From the sounds of it though, you will have to do an engine overhaul. Are you fairly proficient welding? You may be able to weld it with nickle rod. Of Course you'll have to file it down real steady afterward.

Pretty sure that's a dry sleeve block. From the leakdown, I'd go on the assumption it's a head gasket, and hope the head's not cracked.

Gotta pull it.

Thanks to everyone for their comments and help. I have hardly any money into this tractor so far. Good tires, sheetmetal and loader, so worth putting a little effort into. Not to mention a good excuse for my 17 year old and I to work together. Tried some sealant from NAPA, and it stopped the leak while running. Ran into the pan while parked for several months. We will pull the head and see what's there. Thank you again and MERRY CHRISTMAS. Fred

i certainly am serious. i am looking at worst case senario , he says antifreeze in oil and brg noises... you run away from those deals not buy them. from bare block to back to running is nothing to spend 5-6000.00 on an engine. if the head is cracked thats at least 1000.00 or more for head work.engine rebuilding is not cheap, as lots of it is specialized work. unless your a machinest and mechanic and can tackle the work yourself.

Continental G176 is a wet sleeve block. O rings are used to seal the sleeves. The block can crack between the cylinders but mine wasn't. It sounds like you have a cracked sleeve. The sleeves come with the rebuild kit. Aaron

It's time to inspect the bushings at the pivot point on your front end if it is a wide front. The big bushing only has a wall thickness of about a sixteenth of an inch. A loader can make that bushing look sad in a hurry.

I agree with all said by Aaron Ford.
