    I like the Copper Silicone myself. It is the stuff that is $1 more than the black. Comes in tube similiar to the orange, red, blue and black. I forget the specific name. It actually comes out orange though. The best part is its O2 sensor safe. Good for me.. as I have a TBI.

    My friend like the Form-a-gasket 2B. This stays pliable forever. MESSY AS HELL to work with, but it works!

    I use 2B too... but this is for my MANAGER'S 85 Monte that I'm rebuilding, and I don't want it to leak at all on him. The 2B normally works good... but my 454 has no sensors... I'm just checking to see if there are any new miracle products out there that I don't know about! /forums/images/icons/wink.gif

    Thanks!

    I don't like using RTV for anything that tuches engine oil. I have seen it clog up the oil pickup (yes they used too much...but I'd rather be safe than sorry).

    I use Gaskacinch. It works great. I have never had a leak where I used it (not that I don't have other leaks!). Don't use it if it will come in contact w/ ATF.

    You can get it at NAPA. I think they are owned by Edelbrock now. It comes in a old style metal can with a pin-up girl on it /forums/images/icons/smile.gif

    felpro makes the one piece oil pan gasket also and works really well. also comes with new bolts for the added thickness of the gasket and handy little plastic screws to hold the oil pan and gasket up while you are doing it in your truck or wherever.

    There is nothing wrong with RTV used on an engine, so long as you use good RTV. I have used every single type of RTV and will tell you the 3 best to use.
    #1 The right stuff- Napa carries it and is THE best stuff out there. This stuff will seal anything and won't leave little pieces of silicone in your engine.
    #2 Mopar RTV sealant. It is grey in color and awesome stuff too. Get it at any Mopar dealer
    #3 GMS RTV sealant. Available at any GM dealership. Great stuff.
    I have used all of these products day in and day out. Anything else is garbage.

    Use a 1 piece. RTV sucks.
