Sealant path on timing case cover
Ensure that the mating points between the oil pan and crankcase are clean and free of oil.
Otherwise, oil leaks can occur.
The superimposed line (A) shows the sealant path.
Sealing surfaces must be free of oil and grease. Apply sealant to surfaces as a bead 1.5 mm (±0.5 mm) wide. The sealant must be applied within 10 min. The sealant bead must not be spread.
The sealant must be applied in the upper area of the timing case cutout in the center area of the sealing surface since the sealant slides downwards due to placement of the timing case cover.
