Anyone know what the threaded whole is for in the back of the block. This is a picture of the back of the block with the lower intake removed. There was nothing screwed into this spot but it was filled with coolant. I am not sure if something should be there or if it was full of coolant becase the intake was leaking?

The water didn't come from that. It isn't in use but I suppose it could be drilled and used as a oil tap for a gauge? Not real sure what it is, just know that I have one also.
 
Sometimes, especially for cast iron blocks, threaded holes like these are used by the manufacturer to move the block around from place to place while the engine is getting made. There will usually be a similar hole at the other end of the block, but on the other side. Ovbiously, such lift holes in this kind of a position are only useful for so long until they end up covered by other parts, and then another method must be used.

During manufacturing, the engine can be awkward to deal with, and not just placeable on a flat surface as well as moving it from place to place. For this, a lift-arm of sorts is used and they simply attach it by screwing it to the holes in the block and then move the block around. I guess they figured this was the fastest and cheapest way to go during a certain stage of the process.

Holes such as these are dead ends and lead to nowhere. They will not go through inside the block, as this would allow dirt etc. to fall in. Check the hole and see if it is a solid dead end or not. If it is, it is most likely what I'm talking about here. If it goes through to somewhere, then it is not.

Let us know!

Makes sense. I did ceck it out and it does bottom out and goes nowhere. It would need to be a substantial bolt to thread all the way down so makes sense to what you had described.
