replaced intake, wont keep water PLZ HELP!

[Alarus]

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

Sounds like the gaskets didn't seal. Did you use the two small end gaskets? If so, they probably slid around; most people throw them away and just use sealant. The head gaskets also have a frt. and rear and "this side up" to match all of the ports. Hate to say it but it sounds like you need to do the job over again.
