You used the best sealer for threads. Somewhere in there is operator air. Either, you didnt use enough,
not tight enough, or the threads weren't clean. Take the bolt out, clean it, inspect it, reinstall.
Ater your done, walk away. Let it sit for a day.
The Right Stuff is a great prouct, however it is used for gaskets. Valve covers, oil pan, intake, water pump, ect.
