Note:
The bead of sealant must not be thicker than 3
mm, as otherwise excess sealant will enter the
oil pan and obstruct the strainer in the oil intake
pipe.

Note:
Be particularly careful when applying the bead of sealant around the rear
sealing flange (arrows in illustration). - Apply bead of silicone sealant onto clean sealing surface of oil pan, as
illustrated. (Illustration shows position of sealant bead on cylinder
block).
