Hi i'm adding a different gasket design using sheet nitrile 3.2 mm thick 60 shore harness. How much compression would be a good ballpark to use to seal up a valve cover? i'm thinking of using a 2.5 mm spacer to limit compression to 0.7 mm to avoid over deforming it as its not as rigid as some materials. it is not a high pressure situation just whatever you typically get in a valve cover of naturally aspirated engine. the gasket is 11,000 mm^2 area and there are 8 M6 bolts clamping which can easily clamp 50,000 N
Does anyone have any rules of thumb?
