993 sealant strategy is same as earlier cars except the joints where the 993 uses rubber seals at the camshaft and chain housing covers.
Here, I am not sure if it is best to use Dow 111 only or to use some kind of sealant where the gaskets plug into the covers - not where the gaskets meet their opposite mating surface.
The magnesium chain housings need to be free of corrosion and flat, if not a surface grind using emery on glass seems to work fine. Be careful here not to remove any more than necessary particularly where cover goes to crankcase.

Thanks Bob.... I had to replace one of my chain housings there were small pin holes from corrosion.
