[Diy_efi] Reality check - no efi content - long winded

Wed Aug 30 04:26:38 UTC 2006

Bill,

>From my '98 Olds Intrigue service manual for the 3.8:

1. torque to yield--use new bolts

2. tighten to 50 N-m (37 lb-ft) on first pass then tighten an additional 120
degrees. Last, tighten center four bolts an additional 30 degrees

Hope this helps. Reply offline if you would like a fax of the instructions
with the proper sequence.

Garrett

6 new exhaust valves later the heads are ready to put back on.  Anyone
know if the head bolts are reusable or torque-to-yield?  Also,  anyone
know the torque specs for the head bolts, rockers & intake?

thanks,

Bill
