RTV makes a mess to clean up at a later time.
I use teflon paste on clean fresh built engines that have never seen coolant.
On engines like yours, that will have residual coolant in the threads, use teflon tape.
my engine is a "fresh rebuild" and I only put water in it to see if I would have any leaks! can I use the Teflon paste or do I still have to use the tape because of the water?
