I called and talked to my engine builder and he suggested using Permatex "Right Stuff" and to put some in bolt hole first and some on the bolt! well I did not put some in hole first because I knew that some material would definitely end up in my water jacket (cooling system) so what I did was I took some electrical tape and wrapped it around bolt about 1 1/2" to 2" back from end of threads and made sure that it just barely fit into bolt hole, so that it would act like a piston and shove right stuff forward as I screwed bolt in and as bolt was going into threads the right stuff would also be forced backwards off of threads filling the bolt hole with the right stuff and blocking the hole so water (coolant) can not escape! I have no leak(s) at the moment and it is working fine so far, I also believe that the tape was the trick and will work with any of the thread sealers I tried to use! if I ever have this problem again I will try a different sealant so that I will know!
