In various places in the manual (76 400-f) it mentions using liquid packing on mating surfaces (eg. the crank cases where there is no gasket). Previously someone has used some red stuff that has gone brittle and I find bits all over the place (some in the sump). Wanting to avoid this again, what recommendations can anyone make? And when I install new gaskets (with clean faces) would you recommend using it (or other stuff) with gaskets - or just stick to using it just where the manual recommends? Thanks.
