New CF member here , but not new to engines
Hope you're not ignoring post 46 related to over use of silicone for gaskets .
I would not use the type of silicone shown for these covers but rather a product used for sealing metal to metal high temp applications which if applied properly will not squeeze out beyond its needs . I've used it for years assembling Rotax engines & have also seen a silicone gob being removed from an oil pump intake having ruined an engine .
