Got a quick question- What is the hole that is on the top side of the block just behind the intake? Our old block did not have it drilled, and the newer block has a tapped hole that is almost (but not) a 1/4" pipe tap thread, maybe a straight thread. I figure that I'd better cap it if it's oil or water.
What is it, and what size is it? It would save me some time if someone knows.
Thanks!
