No sealer on the o-ringed housing. You may want to run a file or sanding block over thermostat base on the intake, just to be sure that it is flat.

yes have a flat surface that i stick sandpaper on then can sand flat, came out shiny with 600 grit, intake seems to be flat, i used a flat block i have for it, all looked smooth, clean and straight
