That's true if the threaded insert isn't installed. But he writes it's in the block and I cannot remember anything back there being threaded 1/8" ! So IDK!

I think there is a threaded hole facing outward dont thik its pipe thread. Dont remember ever seeing it used. Might be for the trany dipstick tube in a van possibly.
