S-Chassis.com - oil/coolant mix from oil pump?!?

hey guys (user name no longer applies) i didn't want have to do this, as the search button has been extremely helpful in the past two weeks as i have been trying to get my 240 i recently bought to run well, but i can't find anything like this. it's a 90 kae with 84k on it only but the motor has just been rebuilt and has about 2 miles on it. the problem is i have oil/coolant mix coming out of a single bolt in on the oil pump (yes torqued properly). another thing is PURE coolant is dripping down off of my oil pan (drivers side only) maybe a bad gasket but why would it be straight coolant? i would think it would be a blown head gasket maybe, but it has just been rebuilt w/ all new gaskets and the oil in coming from the dipstick and when i take the valve cover off is not milky. the front cover gaskets and oil pan gaskets are liquid gasket so could those be bad? sorry for the extremely long post. i am very confused any help would be GREATLY appreciated.
