i have a 2000 mustang gt with the 01 and up intake with aluminum crossovers. it was recently leaking around the back right bolt on the driver side. i took the intake off, replaced the gaskets, put it back on and it was still leaking. i took it to the shop to let them fix it. they just bought a new intake with the aluminum crossovers and put it on, but they said the new intake had built in gaskets and didnt need more intake gaskets. i have never heard of this. went to pick up the car up today and its still leaking, but now the passenger side front. idk what to do. any suggestions? ever heard of a built-in gasket in the intake? all help is greatly appreciated!!!
