Crankshaft Mains

Step 1. 150 ±20 N•m (111 ±15 lb-ft)
Step 2. Angle tighten 120° ±5°

Crankshaft Main bolts are only to be reused 4 times.

Connecting Rod Bearing Caps

Step 1. 30 ±3 N•m (22 ±2 lb-ft)
Step 2. Angle tighten 180° ±6°

Connecting rod bolts are only to be reused 4 times.

If you are reusing the connecting rod bolts, then a light coating of oil on the threads and under the bolt head are to be applied. If you are replacing the bolts with new ones, they are coated with phosphate and oil and they must be installed dry. 

The information above was taken out from the engine manual. 

If the bolts broke you may want to find the problem before reassembly. Also, those connecting rods are fractured rods, if they were de-torqued they will loose their strength. Those rod caps are an exact fit, if they move around the fracturing will not be the same and they can/will fail prematurely.
