I have a marine power 5.7 vortec carbuerated bought in 2013. I have a vaccum leak. I checked the torque on the intake manifold bolts and there at 12 ft lbs. Most online info I have found say 11 ft lbs is correct. However, the marine power guy says it should be 35 ft lbs. He had to go ask someone so I'm not sure he's right. I have also seen that in their repair manual for older 5.7s and also in a manual for 5.7s that say 35 ft lbs pre gen+ whatever that means. I'm concerned that I'm going to damage my engine if 35 ft lbs is incorrect.
Anyone come across this issue or can anyone verify that 35 ft lbs is correct?
