Air Injection Reaction (AIR) Pipe-to-Exhaust Manifold Bolts LS1/LS6 15 ft. lbs. The torque required for a 3/4" dry steel bolt with 0% lubrication to achieve this tension can be calculated as, Tdry = (0.2) (20000 lb) (0.75 in) (1/12 ft/in) (1 - (0%) / (100%)), The proof load for a M30 metric bolt grad 8.8 is 337000 N. The torque required to achieve this tension with a dry bolt with 0% lubrication can be calculated as, Tdry = (0.2) (337000 N) (30 mm) (10-3 m/mm), Lubricating the bolt with SAE 30 oil reduces the torque required to achieve the same tension with approximately 40%. Videos Design Manufacture When installing the oil pump be sure to have clean surfaces on both parts and to prime the pump itself with oil so that it does not start off dry. 101 Projects says 61 ft-lbs for '69-'89 911s, 34 ft-lbs '65-'68.
