Manifold Sealant

I have a (drip, drip, drip) leak in my engine manifold where a square "cap" in front joins with the rest of the unit. I have removed said cap in the past, but apparently didn't get it sealed properly. Is there some sealant that resists high temperatures and water that is appropriate for this purpose?

Re: Manifold Sealant

How is this cap atached with bolts or is it screwed on. new cap if screwed on, if bolted get gasket paper make new gasket. or ultra black rtv silicone, resists heat up to 260c 500f
