mystery opening under intake manifold

hey folks i am in the process of replacing my head on '88 ranger 2.3l
i noticed a rubber hose connected with a clamp under the lower intake manifold assy. my manuals do not show it nor refer to it. the hose was like a capped hose but i can tell the clamp used was not a oem type one. can anyone tell me
what this outlet is or was for it is directly under the coolant sending unit ie...,
same cavity of intake thanks

tomw has a very good reputation on FTE.tomw has a very good reputation on FTE.tomw has a very good reputation on FTE.
There might have been a hose that ran from that fitting around the back of the cam cover and forward again to a 'TEE' connnected to a heater hose. It would allow coolant to flow thru the bottom of the intake manifold to warm up the incoming mixture for better combustion. The hose is about 3/8" in diameter.
If you look inside, does the intake have that coolant-dye color?

I belive you are talking about the block breather there should be a recantuglar filter stuck in a hole on the side of the block the 20+ 2.3 I have has them... whatever you do don't block the breather off..
