A few weeks ago, I posted that I had blown Head Gasket on My 850. When I removed the head, I found that Piston No. 2 had come loose from the rod. I really didn"t want to do a complete overhaul of the engine until I got my shop finished in about 2 to 3 months. I decided to hone the sleeve a little, replace the piston and head gasket and get the tractor where I could move it. Got the piston replaced and the head gasket installed and torqued to specs. I replaced the oil and the engine started with on problem and ran fine. Didn"t run it long enough to get it warm enough to retorque the head. I filled the radiator up with water and was going to replace the oil and filter before I ran it to get it warm and retorque the head bolts. I noticed water driping from the oil drain. Drained out the radiator and the water stopped. Is there a water jacket that the head bolts go thru where the bolt needs sealent or could I have cracked the block when the piston came loose?

Thanks:

Clay

Thanks Ya'll. I guess I thought all along I should have just pulled the engine and done a complete overhaul. Just wanted to get the tractor where I could move it to a diffenent location until I got my shop completed. The tractor has a loader and the bucket is on the ground. Moving it will be a chore without the engine running. GlenIdaho, you stated that you had a block repaired. I guess any machine shop can do this. About how much would I expect to pay for this repair and new sleeves?

I paid $1,251.87 tax included; for clean motor, regrind crank, install repair sleeve, R&R other sleeves, torque and check rod and main bolts, rebuild rockers, valve job, R&R valve guides, surface head, R&R rod bushings and fit pins, overhaul kit, .030 rod and main bearings. That price is seven years old though. I also replaced all the rod bolts at $8.00 each because I found a weak one while putting it together. Just to give you an idea of the increase in cost, I paid $460.96 for the overhaul kit, they list them on this site for $542. Hope this helps.

From 5w to 140w the weight per gallon of oil can vary from a low of around 6.3 lbs. to as much as 7.9 lbs., so some oils will float on diesel, and some will be the other way around.

Quoting Removed, click Modern View to see

Oil can weigh different amounts per gallon as different viscosity oils have different densities.

Yes if you want to get scientifically technical about it and make a easy answer that explains the situation we were talking about into a hard to give answer; you are correct. Different kinds of oil weigh different amounts but most fall in the 7 lb per gallon range. Heck weighing oil at night will give you a different weight than if you weigh it during the daytime.

So now would you like to talk about how when a refinery sells a gallon of diesel or gas they sell a gallon. But by the time it gets to you putting this same gas or diesel in your truck you are paying for a gallon but not really getting a gallon. You may get a little more or a little less but you very rarely ever get right at a gallon of fuel. And it has nothing to do with how the pump is calibrated.

I know that I don't know near as much as most folks on this board, but I do know a couple of things.

1. Oil floats on water, not the other way around.

Oops, I see that someone beat me to it.

If I understand you correctly, water dripping out the pan drain does not sound good as it should be floating on the oil. You should not need sealant on the head bolts. My 850 developed a crack in the block between the sleeve and block. It was repaired and new sleeves put in. You can do a pressure test to see where the leak is. Pull the pan and connect your air source to the water pump and look for water/bubbles being blown out between the sleeves and block.

Hi Old, Thanks for the correction. I was going from what I've seen such as when I drained my 850. It appeared that the oil came out first and that the water was sitting on top of it in the pan. I always understood oil to be heavier than water. I guess I should have examined it closer. At any rate, water in oil is a problem.

Think about the Gulf when there is a oil spill.
The oil floats on the water because it weighs less.

Per gallon
Water weighs 8.34 lbs
Diesel weighs 7.15 lbs so it will float on water
Oil weighs 6.84 lbs so it will float on diesel
And gasoline weighs 6.07 lbs so it would float on top of all of this.

Yep water in oil not a good thing. Think about what happens to water in the sediment bowl of a tractor. You see the water on the bottom and the gas floating on top. Oil does the same thing if left sit a few hours so that the oil and water separates. If left long enough like that you can drain antifreeze out of an oil pan and if careful even save most of the antifreeze to be used again.

Glen you have it back wards. Oil floats on water not water on oil so the water is at the bottom of the oil pan and drips out the drain plug if loosen a little bit

Could be a number of things. Cracked block, or cracked head from the piston hitting the head hard or a bad head gasket. I do not know if any of the head bolts go into the water jacket but if they do yes that could do it also
