Impossible to get to. In addition, mine was seized at removal so ended up air hammering it off. How to torque it to 17 lb-ft? I don't see any good option. In another world I could torque down the others to 17 lb-ft and use the muscle memory from that experience to wrench the nut by feel. Got to start with the nut first, however.

 

Anything less than 40ftlbs should be torqued by hand; IMO.

Intake should be tightened 'good and tight'. Heat cycle the motor a few times, recheck tightness, usually needs a little more after some heat. Same goes with exhaust mani
