Doesn't the gasket go around all the screws? i believe this is a mating issue. jmo
To answer that question notice how the bolts are inside the "spaghetti zone) and are potential "leak contributors" if not sealed properly. The manual is specific in regards to this and sealant must be applied to threads . A small dab of sealant under the screw heads ensures a 100 % seal. Presssure testing confirms the job is 100% quality work but has suggested in one book some do not even bother doing a 100% seal job and just change the oil mid-season.
