D-17 Coolant in oil:

Hi Allis Fans,
I have a D-17 Series III gas Allis. Yesterday after running the D-17 for a few minutes on the bailer, steam and antifreeze spewed out of the oil filler spout. The oil dipstick indicateed most of the coolant went into the oil. With the head off I can see no craacks around the cylinders (actually it looks like it has sleeves) and i can see no cracks on the top of the block. With the head off and the oil pan plug out it will drip water out of the oil pan drain hole when I fill the block collant chambers. I've rebuilt quite a few engins but never one with sleeves or never an Allis engine. The block is probably cracked a but I'm wondering if this might be something else. Does any one have any information about this problem? If i need to replace the block, does anyone know where i might find one?
Thanks and have a good day

I'm not 100% sure on the D-17 but a good number of Allis tractors are wet sleeve engines and the problem maybe a bad sleeve seal, which is also a common problem with a wet sleeve engine. Pull the oil pan off and then look to see if the drip comes from around the bottom on a sleeve.

Rex, it is likely one of the sleeves has leaking orings at the bottom where is contacts the block. I would pull the sleeves, clean the sleeves and the seating surface using a scotch brite pad, get new o-rings( ensure they are not twisted when on the sleeve, and then use olive oil to lube them up and slide them back into the bore. You can gamble and do one cylinder or do them all. I would also look at the block between cylinders to see if there is a crack. With the ferocity of your leak it is likely a oring went, using bars leaks will not do, pull the sleeve and have a look.

Good luck
 
it could be the seals on the sleeves but you didnt mention the head gasket. i would look close at it. the victor renz gaskets are bad to blow around the pushrod holes . the fel pro blue head gasket seals alot better even though it doesnt have the copper orings like the victor .
 
You can pull the oil pan, fill the block with water and look to see where its leaking from. Pretty good chance its coming from a sleeve seal ring. At least this way you'll know.
