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).

- Immediately attach oil pan and tighten bolts in
described sequence:

Note: - Tighten bolts -1 to 18- diagonally to 5 Nm.
- Tighten bolts securing oil pan to transmission to 45 Nm.
- Tighten bolts M10 -arrows- to 40 Nm.
- Tighten bolts -1 to 18- tighten diagonally to 15 Nm.
Replace seals and gaskets.

When installing the oil pan with the engine removed from the vehicle,
ensure that the oil pan -3- is positioned flush with the intermediate
plate -1- at the flywheel end (i.e. oil pan should protrude dimension "a"
= 0.8 mm from cylinder block with respect to the cylinder block -2-). After installing oil pan assembly, the sealant must dry for approx. 30
minutes. Only then may the engine be filled with oil.
