Installation Procedure
Important:
^
The alignment of the structural oil pan is critical. The rear bolt hole locations of the oil pan provide mounting points for the transmission
bellhousing. To ensure the rigidity of the powertrain and correct transmission alignment, it is important that the rear of the block and the rear of the
oil pan must NEVER protrude beyond the engine block and transmission bellhousing plane.
^
If replacing the oil pan gasket it is not necessary to rivet the NEW gasket to the oil pan.
