Leak at back of intake following Cobra install...

I junked the rubber gaskets on mine. I put dimples on the mating surfaces of the block and manifold, then RTV'd it up. Dimples keep the dried up silicone from sliding around in there.
 
Yeah, I didn't use the rubber gaskets that were with the set... just RTV...

apparently not quite enough, sucks...


Guess I'll get on that here soon...
glad I got one install under my belt, second time around shouldn't be as bad, lol i hope...
 
It may not have been the amount you used but the time you allowed before squishing it all down with the intake. I'll usually leave the sealant to cure a while (30 to 60 min) on a normal day so that it's "tacky" before dropping the intake on it and torquing it to spec.

Otherwise, you run the risk of squishing sealant out of various places while you're doing the torque sequence.

--also--

Everyone has their "favorite" sealant that they like to use. I like the Permatex Gasket Maker that comes in the "Cheese Wiz" can. No muss, no fuss.
