I installed my new Weiand Team G intake today, and on the intake manifold to head gasket I put some RVT silicone around the coolant passages, but only on the cylinder head side. My question is should I put some on the manifold side of the gasket also? I'd didn't think of it until after I installed the manifold, so I looked over the directions that came with the gaskets, but it was specific as to if I should use it on both sides. Any thoughts :confused:

This appears to be a subject of great debate but I have done 10 manifolds and none ever leaked and yes I applied sealant to both sides.

Thanks Cali.....tommorow I might pop it back off and put some on the manifold side. It's no big deal, since I haven't even torqued the bolts to proper spec yet :cheers:

MAKE SURE YOU ARE USING A SILICONE THAT IS OK WITH ALUMINUM!!!
The stuff that you get from the hardware store for sealing bathtubs and rain gutters will actually corode aluminum!! Use only a silicone sealant approved for automotive use. And only use a thin coat on both sides. Too much and it will ooze out and restrict flow or break off and plug up a radiator or heater core tube.

I use this on both sides.

As usual Paul is on the mark. :thumbs: I use the same.

Paul and Cali--I'm using the same brand, but I got the high-temp black silicone.

Geezer--I did only use a small amount, just enough to seal it :cheers:

thanks on the corrosion info, i was the same but have used the other in a pinch :thumbs:
