possibly trashed block?

[JackstandTSi]

I am trying to get my motor on a stand and after 2 trips to lowes for bolt 2 of my holes and a m10 and 2 other holes are a m12, i looked inside one of the m12 bolt holes and saw that the hole looked to be punched threw the block, and expert opinion would be great.

Get ur self a tap and die set. U can fix the threads like new

The threads are good its just whoever had this block before me i think went to far on tapping them and has pushed it threw into a oil or coolant gally.

If its not leaking under perssure I think I would be fine

Your FSM should show the oil and coolant galleys, but regardless you should be able to weld, re-drill and tap the hole no problem!

Here is another pick i snapped before i left my mothers, i stuck a screwdriver threw the hole and looked threw the gally and this is its outcome.

Fortunately that is an oil return & not under pressure. helicoil it & use thread sealer, you'll be fine.

That looks like it is into the oil drain galley. It's not so simple to weld up and tap. Cast iron doesn't weld like mild steel. You can't just use a mig welder and fill it in. It will not hold. If your not experienced in how to weld cast, don't try it in something like this. You will end up with some metal chunks in your oil pan and a bolt backing out of your block.

If the threads are in decent shape or you can get them in decent shape and the rest of the engine is good, then I would use some sealant on that thread when you bolt up your transmission.
