Ensure that the sump and the sealing surface on the lower crankcase are free of all oil and debris.
Apply a 2 mm bead of sealant (1) around the perimeter of the sump and the oil suction port opening. DO NOT over apply the sealant. More than a 2 mm bead is not required. Refer to Adhesives, Fluids, Lubricants, and Sealers for the correct part number.
