Great idea! I wonder if a cylinder ring compressor would work. Heck I have thin sheet stock to compress the rings. Yes the block bore is chamfered and somewhat polished. Let's say it's very smooth for cast iron. What's happening is the friction from pressing the sleeve is firstly pushing the...

Oh I do have a mill and lathe. I thought of widening the grooves of the sleeve. I'm thinking it's just not enough room for the rings to glatten out and squish. When pressed they are cutting ong the edges of the oring groove of the sleeve. Now that's just my observation guessing as you can't see...

I've got a little 25 hp chinesium tractor. So no real formal specs to toss around. I rebuild this thing new last summer. All new internals and seals. The sleeves are wet press in with two 4mm thick orings as seals on the bottom of the sleeves. Seals off the coolant from the oil sump. I...

I had freshly rebuild my jinma farm pro 2420 last summer. Had very little hours on it. Checked the oil this spring and it was full of antifreeze. I tore this thing Down and inspected it with a fine tooth comb. No cracks nada. I added pressure to the coolant side and it seemed to be leaking from...

Our lots are full here. I know one thing! I have been in the market to need and want to buy a tractor. The prices are frigging unreal!! Even used implement prices here are stupid compared to a few years back. Chinese tractors once sold new for 3-5 grand new now they are selling for 7-9...

Yes I didn't think of that. There are freeze plugs under the rocker arms. However I think I'm on the trail. I put it all back together with a new head gasket. I pressurized the coolant side to 20 psi. I've got drips coming from the rear sleeve. It's not really clear if it's from the outside of...

No she's stone age basic.

Thank you so much for your insight! Last night I suspected a rolled Oring on a sleeve. The more I laid in bed thinking. There are two Orings. It would have to roll both or pinch/ break both. Possible YES likely No. Then I kept thinking about the coolant so high in the engine. All the way on...

That's my sneaking suspicions also. I'm not sure how to rule out a head gasket or the head though.

It does have a mechanical pump. What os puzzling is the oil is not milky. I have no idea when this happened but nothing indicates it's been ran like this. It's almost like a frozen cracked block or cracked sleeve. This antifreeze is new and like 30 below plus I live in Alabama. I have no idea...

Here are a few pics of the head and cylinders.

I hope somebody will give me a little direction or outside insight. Please! I have freshly rebuild this little tractor last summer. Everything new but the block. It was meticulously build to the best specs i coukd obtain. Furthermore, It was used lightly and only a few hours this year. Never...

I thank you all so very much for the replies and help!! This is what I needed! Thank again!!

FOUND IT!! Well.... what in the hell goes in front of the seal to keep it in place if it’s pissibke to push out? Why did it push out? Why is it sucking air instead of pushing fluid out into the crank case? Sucking air but blowing the seal out! Hmmmm There is a groove but it doesn’t look...
