4.2 help

OK so 4.2 97 F150. REad in exhaustion about lower intake gasket. Story is PO had a little loss of coolant. Drove truck 20 miles, never overheated. Got home, it was missing a bit. Shut it off. Sat three months til yesterday. I pulled spark plugs. Cranked engine and oil sprayed out rear cylinders on each side. Oil has some coolant/milky residue. Does this sound like the intake gasket? Anything else I should check?

update

As I have started tearing down the engine to get to the intake gasket, I noticed oil/coolant mix in the air intake tube, up near the throttle body, and in the upper plenum runners. Any thoughts?
