Lubing seals
Just a bit of history of me, for the past 6 months I have been taught in my aircraft hydraulics that we wet our seals down with hydraulic fluid (thinner petroleum or synthetic based oil depending on the aircraft) so they seal better. Yesterday I was installing a new valve cover gasket and read in my Haynes repair manual that the sealing surfaces should be oil free or leaks might occur. I was wondering if anyone had any experience with seals leaking due to wetting down or any other input?
