That may be true, but the seal on the PS box is not a flat gasket type like
say a rocker cover or a water pump. It is a flat ring seal round a short
cylindrical part below the top plate. I always torque everything correctly
where possible. I wouldn't have thought it to be majorly critical in this
place as the top plate does not do the job of sealing in the fluid.
