    i use silicone rtv and it works awesome. you basically have to clean the heck out of it though, to make sure your getting good adhesion. brake parts cleaner and a sock works very well to clean the surfaces.

    I only run RTV and have had zero issues. Make sure you let the RTV skim over before you put it together it will seal better.

    You will find about a 50/50 mix of people that run the gaskets or RTV it is kinda a personal preference.

    The Right Stuff. The only gasket material I use on non-pressure or high-heat sealing surfaces.

    i pretty much use only gaskets on my dd, and mostly silicone on the k5. gaskets are good when the clearances are consistent and no damage is present, but the silicone allows you to adjust for minor imperfections on the mating surfaces.

    speaking of mating, i'm actually not a fan of silicone on chicks, and a gasket would be really strange in that application. :wink1:

    You're right, when it comes to ladies, it's all about the liquid latex... :D

    I used just the gasket last time... sealed just fine.

    I had to "order" new gaskets from Kragens. Auto Zone said they don't have such a thing (dumb asses). I even had the part number(fel-pro 55350). I will put them on and if it leaks anymore I will silicone it too.
    THANKS EVERYONE:bow:

    I used just the gasket, but I can't see where rtv would hurt.
