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.
