intake leaking

i just noticed the drivers front of the intake leaking antifreeze.I installed a new Edlebrock air gap with new gaskets,torqued the bolts to the proper sequence and it leaks.aside from the gaskets,would you guys replace the intake as well to be on the safe side? [509 merlin3 with iron heads] it is avery small amount of antifreeze.thanks for the help

Re: intake leaking

Could it be leaking from the front couple bolts, or any water plugs you have. Those all could use some sealant or thread tape.

Re: intake leaking

Did you use a front and rear gasket, or a bead of sealant around there. I've had much better luck with the sealant, rather than the gaskets. Could it be that your block or heads were shaved a little?

Re: intake leaking

I would say either warped flange on the intake or warped surface on the head. Take a straight edge and check.

Re: intake leaking

Keep an eye on your oil to make sure its not leaking into the intake valley also..
