I want this intake sealed up perfectly, and I really don't like RTV that much. What do you guys use on the intake manifold when you seal it on the heads? Can I just use copper spray and gaskets or do I need some RTV or silicone? Use the china walls or pitch'em?

 

What's wrong with RTV, works great.

I hear some don't use those plastic/rubber parts ( i guess the china walls), but don't quote me on that.

 

I use "The Right Stuff". You can get it AutoZone for $13 a can. It comes in an easy cheese-like can. I know it's expensive but it works 100 times better than Ultra Black. Once this stuff dries, it's almost indistinguishable from a rubber gasket.

You can also try "Honda Bond". I dunno if that's the real name but it's this crazy sealant/RTV that you can get at any Honda dealer. This stuff puts The Right Stuff to shame. I know it was expensive, and you might as well be welding the intake on because it's so damn tacky, but it will NEVER leak....EVER. I used this on a boat intake once...the kinda job you never want to do again unless you take the engine out completely.

 

After some extensive searching on opinions on the subject I've come up with this. What do you guys think? I'll use copper spray on the head side of all the gaskets to stick them in place (my china walls are the good ones with tabs to keep them in place as well) and a little bit of RTV around the coolant passages on the intake side and in the transition gaps between the china walls and main gaskets. Sound effective?
