I have to replace a valve cover gasket, I don't have a wrm place to let it set so I have to do it out in the cold. will the RTV set out there in that crappy winter weather?

Depending on which kind you use. I think some of them don't require a set time. Are you using the basic black rtv?

When I had to use RTV black for a temperary oil pan leak patch, I used a hair dryer on low for about 5 min, That helped it set and lasted until I got home.
Hope this helps

Yet it still amazes me that so many people choose to be stupid.

Use the ultra blue. I used it to patch a hole in a oil pan. It was 7 below out side. I let the oil leak out over night. Plugged the hole in the am. filled with oil 2 hours later and drove it out of the woods. hell i drove it for 3 months till summer time before i put a new oil pan on it..

The blue works in the winter. Ive used it many times on cars, and I normally do valve work on the bikes during the winter months.

Well, yall be me to it! If you haven't bought any yet go get the blue, I recomend keeping a tube of a couple different types in your tool box.

If your using a new gasket just clean the surface very well and you shouldn't need a sealant. Most car manufactures advise against a sealant on anything where the sealant can break away and get into the system to clog oil ports or the pump screen.

if you are replacing a gasket with a new one and the part in question is not damaged you dont need anything. The only thing i would suggest is using permatex red hi-tack spray. It is simply a gasket adhesive that will hold it in place while you assemble a part.

But yes RTV will harden when cold...it just takes longer.
