Main bearing cap bolts there is a outer cap bolt that are torqued to 20 ft lbs + 1/4 turn. Then there a inner cap bolt that are torqued to 15 ft lbs + 1/4 turn. Con rod bolts are torqued 20 ft lbs +1/4 turn
Crank shaft main bearings.46-52 Nm tighten in 2 or three stages.
Con rod bearings 14-16 Nm1st step. 2nd step 39-45. Or if you have access to angle torque 60-65 degrees. Rule of thumb ring gap is .005" per inch of bore. eg 3" bore .015" ( thou of inch)
Main bearings: 60
Connecting rod bearing cap nuts: 34
Rocker arm shaft bolts 180 INCH POUNDS
Intake manifold: 168 INCH POUNDS
Exhaust manifold nuts: 18
Crankshaft vibration dampner bolt: 112
Cam shaft sprocket bolts: 70
Head bolts: 76 - 83
If you need others please let me know, when working with Aluminum parts go easy as they can strip easy.

1. Check the connecting rod alignment If either the bend or the twist exceeds the specified limit,the connecting rod must be replaced. Bend per 100 mm (3.937 inch) Limit: 0.15 (0.0059) Twist per 100 mm (3.937 inch) Limit: 0.20 (0.0078)
2. Measure the connecting rod thrust clearance. Use a feeler gauge to measure the thrust clearance at the large end of the connecting rod If the clearance exceeds the specified limit, the connecting rod must be replaced. Standard: 0.16 mm - 0.35 mm (0.0063 inch - 0.0138 inch) Limit: 0.40 mm (0.0157 inch)
Carefully check the rod bearings. If even one bearing is found to be damaged or badly worn, the entire bearing assembly must be replaced as a set. Reinstall the bearings in their original positions. Apply plastigage to the crank pin.
Reinstall the rod caps (12) to their original positions. Tighten the rod cap nuts. Torque: 54 Nm (40 ft. lbs.)Note: Do not allow the crankshaft to rotate.
Remove the rod caps.
Measure the width of the plastigage and determine the oil clearance. If the oil clearance exceeds the limit, replace the rod bearing as a set. Standard: 0.019 mm - 0.043 mm (0.0007 inch - 0.0017 inch) Limit: 0.08 mm (0.003 inch)
Clean the plastigage from the bearings and the crankshaft pins.
