i replaced my intake and switched everything out, went kinda good (other than running 60 miles a few times for little thing) a little wile ago i changed the oil, and went to put the coolant in and its leaking relly bad at the back drivers side of the engine...could it be a gasket, or what? please help ive been trying to get her running for 4 days now this is really pissing me off, all we have is a van that needs new rotors and brakes and a truck that needs a starter, other than this prob my mustang is the best running(well now its not running) any help is greatly appreciated
