What is the best way to determine where the water is getting in the oil on an Allis B. I am getting older and slower for a few years ago I would not be asking for help. Thanks and any help would be appreciated. I have checked the freeze out plugs in the head and tomorrow I will pull the head. Bob N.

DON"T PULL THE HEAD !! Drop the oil pan. Fill the radiator. Pressurize the cooling system and wait and see where the COOLANT may be coming from.

Is it water or coolant? Clear or green?

if not the freeze plugs, then normally the liner o-rings.... easy to add a cup of BARS copper engine block sealer and run for an hour.. should seal it up... or you can pull the pan like Dr said and verify.

I'm with the good Dr. Drop the pan and pressurize the radiator. I bet the sleeve orings are leaking.

How closely did you check the core plugs in the head? I had one that I swore the ore plugs were good, but when I pulled them out, one had a tiny hole that wasn't visible from the top.

I, personally, would change them. I bet you will be surprised how bad they are when you get them out.

This is why one should never disassemble the engine first. Drop the pan and pressurize the system and FIND the leak so then you KNOW where the problem is.

I have the pan off and the engine block clean but having trouble pressurizing the radiator. I am going to put some red food coloring and go at it again. I do not think it is the cylinder O-Rings and leaning to a head gasket. The tractor set all winter and it took almost a gallon of water to fill the radiator. I changed out the head last summer and probably did not check the head for flatness but with all your help I will get it. I think I have about 8 heads laying around.

Don't know if there's an Auto Zone near you , but that's where I got a loaner cooling system pressure tester . It fit my D 15 rad . Good luck !

I did not think it would fit a B but will try

Kit I used had a tapered fitting that goes inside the radiator inlet. Worked for me
It does require a $250 deposit, but it's refunded when returned. Good luck

They make a dye you pour into the cooling system and when a black light is pointed up into the bottom of an engine, the leaks really jump out. Food coloring in a bright color works also but the dye really helps as you can easily see "runners" such as a crack someplace that drips someplace else.

I used dye to find a hydraulic leak once. Worked really good. Not that spendy either.

I have a "TracerLine" setup myself and several different dyes for different fluids. None are expensive and will save hours chasing something elusive. The lamp is expensive up front and I went with a 12VDC unit as it's bright enough to see a leak in broad daylight. Any black light will work, but the brighter the better to get the leak to "jump out".

Did the pressure test and I have water dripping from the middle main and would that be the head gasket or do I need to install another head ?

Posted By: steve(ill)

hard to tell a gasket from the head without pulling and inspecting the gasket and pressure testing the head,... i would look close and make sure its not running off a liner edge.. Normally a head gasket is high enough up that you would only loose 2 quarts of antifreeze.... a gallon would mean lower spot on the block.

I am guessing 1 gallon for my daughter in law added the water but when I drained the water off of the oil it was less than a gallon. I might just install another head and take my chances. Thanks for your help

Make sure the block isn't split down the middle.

are you talking about the cracks between the sleeves

Date Posted: 29 May 2024 at 6:17am

YES.

My understanding is the cracks between the cylinders at the top are common and of little significance; cracks at the bottom would be bad though.

Posted By: DrAllis

You are correct, but when there's coolant in the pan, one has to be SURE the block isn't broken on the bottom. The coolant is coming from somewhere.

I am sure it is coming out of the center main for I cannot see or feel any water around the liner or block

Sorry for the late update but just received the head gasket and pulled the head today and one thing I noticed was the head bolts came off easy but I should have checked the torque before I removed them like I said I am 84 and moving a little slower upstairs. I have another head and going to use it. I replaced the engine last year and it was not running right and found that the head had sucked a valve and so I changed that out and my son said they did not have the water problem until I changed the head. I am going to replace the freeze out plugs and use another head and will keep you informed. Bob

Update, I put one gallon of water in radiator and still have the same problem. After a closer inspection it seems like the water is coming from #2 or #3 sleeve so I am going to pull them and check it out further for I have plenty of sleeve sets and O rings and will keep you informed. Bob

I have done this with success.... Pulling the motor is permanent,... but a LOT OF WORK..

if not the freeze plugs, then normally the liner o-rings.... easy to add a cup of BARS copper engine block sealer and run for an hour.. should seal it up.

I am at the point of no return for I am looking at the sleeves and I think I will pull them and should take care of it or trash the block and build another and go from there. Thanks for all the help but should have it done tomorrow. Bob alias allisca

Sorry for not getting back sooner but had a lot of honey do's to do. The problem was the cylinder o rings for replaced them and problem solved. Used the rad pressure tester from advance and that did the job. Thanks everybody for your help Bob
