Hey, i replaced my gasket to see if the IM still had a vacuum leak, and still is leaking, i sprayed a little water around the flange and you clearly hear the water get sucked in, should i put rtv sealant on both sides of the gaket to make it seal properly ??
Btw, i just installed the edelbrock turbo kit, and it's the performer x IM that's making me get this vacuum leak ??

thanks for the help !!
