Apologies in advance for the 3 threads in a matter of days. I noticed a small leak coming from between my exhaust manifold and my exhaust elbow. Ive done quite a bit of searching and cant get a set answer on what gasket to use and if it requires sealant or dry. Also how would i go about torquing my nuts down after replacement of the gasket. All require a wrench, not a socket. ( 2 are threaded rod that my oil filter mounts to and 2 are nuts under the riser itself). I have checked and my surfaces are flat. So im thinking i should be able to get away with just new gaskets.
