d14 block cracked

[Squigdemahoogit]

I cleaned the top of the block of my Dad's d14 and noticed a hair line crack between each of the sleeves. (i have pics but don't know how to put them on here) we where wondering if there is a cheap way to fix this. we just spent $420 to get the head cleaned and a complete valve job done. The engine had oil in the antifreeze and antifreeze in the oil. so we are thinking that it is completely lunched. any thoughts?
thanks eric

The cracks at the top are not a problem. The head gasket seals the sleeves. If you have water in the oil, the most likely problem is the o-ring seals at the bottom of the sleeves. An IT manual will help you do this repair - it is not expensive. Other possibilities are a cracked head or cracked block. I suggest checking the o-rings first, then the head.

Oil in the water can be cause by a bad head gasket. When you removed the head, you could have examined the gasket to see if there was and indications.

If the block is cracked on the deck surface between the cylinders there is a good possibility that the lower bores are cracked also. I can furnace braze the block for you but then we will have to machine the bores and deck the block.We will also check the line bore. You have a serious problem and this is the only way to fix it. The cost for the welding and machine work will be $950.00. Please visit my web site and you can call me with any questions.

Hard to find those blocks without hair line cracks between the cylinders. The hair line cracks are caused from the engine over heating. That is the reason so many wet sleeved blocks of any make have them.
The most common cause of water in the oil on your type of engine of that age is from the core plugs in the head under the rocker rusting and getting pin holes.

Not many of these engines will be cracked at the bottom that have not cracked from freezing. When that happens the cracks on the top will be wider and will be uneven. You can easily tell the difference.

Head gaskets, lower o ring seals and cracked sleeves all can cause water to get into the oil.
If the water has been found after years of setting out in the weather you may never find the exact cause after you have the engine rebuilt.

Check the block well before giving up on it. A used block may not be better than the one you have.

I think they should have been factory installed- they"re all that way now, anyway!

thanks for the replies. i forgot to mention that the shop we bought the tractor off of used silicone with the head gasket and there was a spot that had no silicone and i think that is where it was going back and forth. none of the gages have ever worked. when i had the oil pan off i didn't see any cracks and i left the water in it to see if any would drip but i didn't see any. I think that we are going to try a new head gasket and see if that fixes it. if it doesn't then my dads only out $60 plus our time and it not like it is hard to lose $60 around the farm. when we change the oil in it we will look carefuly for water in it. if we see some then we will know we have a more serious problem. but until then we don't see a point in spending $1000 on a tractor that we don't use very much.
