   • The block assembly and the lower crankcase surface must be free of contamination prior to applying the sealer.
   • The lower crankcase must be fastened to final torque specification within 10 minutes of applying the sealer.

   Apply a 3 mm (0.12 in) bead of sealer (2) on the lower crankcase. Refer to Adhesives, Fluids, Lubricants, and Sealers .

8. Apply an additionally 3 mm (0.12 in) bead of sealer about a length of 20 mm (0.90 in) in the outer regions (1, 3).
9. Apply an additionally 3 mm bead of sealer about a length of 5 mm (0.20 in), in the outer region (4).
