340 exhaust manifold leak

[Kllrbee]

Hey guys,
Leaking coolant out the passenger side in the back. Dripping down off the gasket.
Do I just put some high temp rtv on the bolt/stud? Or replace the gasket? Or both?
Thanks

I would try sealant first. Quick and easy. Coolant won't leak from the gasket.

I have used a lot of different sealers and this is what I like the best never had a leak, sets soft, comes apart easy.

HERCULES 8 oz. Can Megaloc® Thread Sealant, White - 20CM14|15806 - Grainger

Red loc tite. Back stud penetrates the water jacket. See if you can double nut it to get it out, chase the threads and re install with red loc tite. A lot of work but problem solved.

Thanks guys.
After doing a search, I see that this topic has been discussed thoroughly before.
Sealant should do it.
