ok whats going on guys, i have an 89 stang that i just picked up running but with no oil pressure. i pulled the motor out and changed the oil pump and rod bla bla bla..i put the motor back in and she will start but #1 wont idle...#2 on the rear drivers side of the upper intake manifold that is leaking coolant..it looks like it should have a hose connected but i dont know where to hook it up to? i heard is was just a vacuum line but it is pissing out coolant when the car is running..it it possibly that it is a vacuum line but coolant is getting in because i didnt change the gasket?
