crawled around it and looked at all sides,didnt see anything off the pan,didnt look for one coming off block.Hope i dont sound to stupid here but doesnt the the head and block have ports that the oil travels through from the top to the crankcase?? when you put oil in the top(valve cover) doesnt oil travel done to the oil pan through these ports?
There has to be a crankcase breather setup somewhere. When there use to be no hoses coming off of the oil pan then there was a tube off the side of the block or breather caps on the valve covers. The pressure that builds in the crankcase has to be relieved someway or you will blowout the valve seals and oil rings on the pistons.
