c. Loosen all the bolts completely.
d. Tighten all bolts to 25 - 34 Nm (18 - 25 ft. lbs.).
e. Turn all bolts 86 to 91° clockwise. If an angle wrench is not available, tighten bolts to 75 - 84 Nm (55 - 62 ft. lbs.).






Install camshafts and camshaft brackets and tighten all bolts as shown to 2 Nm (17 inch lbs.). Then tighten all bolts to 9.0 - 11.8 Nm (79.9 - 104.2 inch lbs.).























Install crankshaft and main bearing caps and tighten bolts to 46 - 56 Nm (34 - 41 ft. lbs.).
Apply new engine oil to the bolt thread and seat surfaces.
Prior to tightening bearing cap bolts, shift crankshaft back and forth to properly seat the bearing cap.







NOTE: Apply new engine oil to the bolt threads and nut seating surfaces. Tighten connecting rod cap nuts to 14 - 16 Nm (10 - 12 ft. lbs.). Then turn the nuts another 60 to 65° clockwise with an angle wrench, or if an angle wrench is not available, tighten them an additional 38 - 44 Nm (28 - 33 ft. lbs.)
