The main bearing caps are numbered 1 through 7. Ensure that the main bearing caps are in the correct location. The part number on the main bearing cap must face to the right side and toward the front of the block. Orient the main bearing cap correctly in the cylinder block. If caps are oriented correctly, the tab slots that are in the block and in the main bearing caps will be adjacent.Note: Use SAE 30 oil or molybdenum grease to lubricate the threads and the washer face of the main bearing cap bolts.
Torque the main bearing cap bolts to 95 N m (70 lb ft).
Put an alignment mark on each cap and bolt.
Rotate the bolts for an additional turn in the clockwise direction to 90 degrees.
