Default Re: oil pan gasket sealer?

If the gasket is used this way and "glued" to the pan, it should work, even from underneath, if you use the jacking stud method. Rather than juggling the pan, fighting the rope seals, and trying to start the pan bolts. One important thing is to make sure the pan flange surfaces are straight, so that they don't make the gasket fill in too big of a gap due to crookedness.
I also use Hylomar Blue on cork and paper gaskets (e.g., gooseneck, water pump, lower water inlet fitting). Apply a very thin layer to both sides of the gasket, not to the metal. I have found over the years that it does not harden like other RTV products and is pretty easy to remove with a simple scraper.
