What does this port on M50 oil housing do?

[Jon K]

There is a big allen plug on the oil filter housing as seen here with the arrow pointing to it

Can anyone please clue me in as to what it is for? I'd like to hook up an accusump or oil cooler to the stock oil housing but I am not sure it'll be possible - what does this port do? Is it pressurizied oil? Any help is appreciated!

Off-topic, but does anyone know the torque specs on the 3 bolts that hold the housing to the block?

not sure about that point but this might be useful for what you need

most of the extra holes in stuff like that is for access to the internals for machining or adding a check valve
