ok to make really goos seals on threads would it be a good idea to put some copper sealant on teh threads, or should i get teflon. mind you this is for oil and coolant which is very hot. i know there is a special teflon for it, not sure what color, so what color is it, and would the copper sealant on the threads be better?

 

use the tape... thats what its made for.

 

do you know what color?

 

 

yea i checked right after i posted that lol its yellow thanks
