i'm installing a edelbrock performer intake and the install instructions say to use edelbrock gasgacinch #9300 sealer on the intake gaskets. can i use rtv ultra black or something else?:confused:

yea...thats fine..used it on mine...no leaks!

perfect... thanks

Yeah, I used the orange, it worked just fine.

What intake gaskets are you using? There are some fel-pro 'blue' ones that don't jive well with certain RTV sealers - they basically turn the 'blue' on the gasket surface into a kinda mushy mess after while. That may be why they are recommending that sealant?

I have used the black silicone stuff on the blue coated fel-pros though, and it works just fine.

they are mr. gasket brand. they look like they have a silicon seal of some type around the port openings.

If they are the cardboard ones with the plastic 'seal' around the ports, I'd stay away. I've used them and had nothing but problems. The fel-pro blue ones work much better.

I always put a nice bead of the blue RTV where the intake seals up. Never had a problem with it...

I have used the gasgacinch many times and prefer it to others for holding the gaskets in place durring installation. That stuff can be very sticky and if applied to one side of the gasket and the mating surface, it's almost like contact cement. It doesn't fill voids well at all like the RTV so don't use it by itself on the ends of the intake like you would the RTV. It's also good for holding the gasket to a part that you can take off the vehicle to clean as apposed to coming of in places that are hard to get at. Of course that only holds true if you apply it to one side of the gasket that is attached to the part your removing LOL. If you misstakenly put it on the wrong side, god help you if you can't get at it with a wire wheel or something. I had an intake that had been port matched to some heavily ported heads. There wasn't much surface area left between the ports and I would get a vacume leak just after a few days. It seams that the gaskets would move just enough to keep it from getting a good seal. After using that sticky crap I never had a problem again.
