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.
? Do not reuse the oil pan gasket.
? It is not necessary to rivet the NEW gasket to the oil pan.
IMPORTANT: Be sure to align the oil gallery passages in the oil pan and engine
block properly with the oil pan gasket.
