What hole is the one that is circled red?
I believe the blue circle is an oil galley plug, but I do not know what the other hole is.
It is threaded.
(This is not my actual picture, so mine is not filled with orange RTV.)
I was replacing the lower manifold gasket and noticed this hole filled with grease. No cap or plug.
The block is a 1990.
