Adding gasket sealant (RTV, Hondabond, whatever) to a surface that already is sealed with a gasket will cause a leak.

One or the other.

I have yet to have a problem using liquid sealant and either a oem, aftermarket, or home made gasket in conjuction with one another.
Like I already said, it is a common practice to use "Right Stuff" liquid gasket or something similar with the valvecover gasket.
How can a liquid that fills in the cracks or any place where a perfect seal is not made then hardens to create a seal, hurt the seal itself? That doesn't make any sense.

And, yes, Dave all of the pipes have beaded lips. I'm not worried about them blowing. I'm worried about them leaking air and the goal is to prevent that from happening.
