Clean new (rubber) gasket and both mounting surfaces with carb cleaner. A thin but adequate bead of oil-resistant silicone sealant on both sides of the gasket, with special attention to the corners and any contoured bits, then let it 'cure' or 'go off' for an hour or so. Only FINGER-TIGHTEN the cover mounting bolts evenly, then add another 1/8th turn or so. Be careful; over-tightening will screw-up the whole job and you'll need to start all over again. Good luck...
