Don't worry about it. Good-n-tight will be
ok, as long as you smear the bolts with a
little never-sieze grease. You can't get a
torque anything on the back bolts anyway.

I usually tighten those to medium, or extra medium.

Just a little FYI, the torque specification in my X-9176 Helm's service manual supplement calls for 45 Nm or 33 ft. lbs with no regards to a pattern. HTH

Hey, Black Ty! GM Supplement X-9276 Ty/Sy Service Manual Supplement (Do yerself a favor and get one!) page 6J-13 says, "Turbo-manif bolts 33 Ft/Lbs (tighten criss/cross start with 15, 25, 33), Coolant return line clamp 16 In/Lbs, Coolant Feed line bolt 26 Ft/Lbs, Turbo oil return line bolt 35 In/lbs, turbo coolant feed line connector 16 Ft/lbs, turbo oil feedline nut 13 Ft/lbs, and turbo coolant return line connector 16 Ft/lbs. Sounds like a lot, but you will HATE yourself if ya don't do it right. Happy Holidays! Gary & Ty1845.
