Metal shifting and warping during heating and cooling cycles---material gaskets don't like that. Flexible engine sealer accommodates metal shifts much better. Don't know brand name of stuff I used but can find out. Think it's Wurth... not sure. Grey stuff. Spend a great deal of time cleaning matting surfaces before covering house...
Sealer applies in very thin coat... cover only. After progressive torque down, small, even extrusion of sealer around entire seam of case is inspected to confirm accuracy of application. (If I don't see extrusion in any area of seam... I'll pull cover and do over. Point being to know without a doubt that it's right.)
