    I double checked again and found this out for a 2002 6.0L lq9. Connecting rod bolts are 15 ftlbs with additional 85 degree's. The main bearing inner bolts are 15 ftlbs (first pass) final pass is 80 degree's The outter bolts are 15 ftlbs (first pass) and final pass is 51 degree's. The outside bolts are 18 ft lbs.
    The above procedure is all done in the bolt tighten sequence in which its going to be hard for me to show you, due to my computer problems. The degree is an additional turn from 12'00; ie 45, 90, and 180.
