Upper Plenum Bolt Torque
I still think there's some confusion here over the correct torque. If you look further on in that section of the manual, the 40 - 61 in-lbs is referenced for the "stud bolts." I showed (via email) the shop manual pages to Tony the other day and asked if he thought this lighter torque was just for the two studs that are meant for positioning the Upper Plenum and gasket rather than the bolts themselves. Not sure that 5 ft-lbs will hold up to all the vibration but would suggest in the absence of a certain answer that you use 5 lbs, and re-check every few weeks for the first 3 months.

Don't use a torque wrench that measures in ft-lbs. The error is much worse than a torque wrench that measures in in-lbs. Probably close to 16 times worse.
Remember if the wrench has a 10% accuracy, this accuracy is applied to the overall operational range of the torque wrench, not the measurement you're setting the wrench at.
Go by the 61 in-lbs and use the appropirate wrench is my advice.

I'm using a calibrated in-lb clicker-style torque wrench that I borrowed from work, so I know it's accurate I agree though, ft-lb wrench will not be as accurate.
I ended up torquing the bolts to 72 in-lb (6 ft-lb) this morning. I'll check the torque on them late tonight after my car is cool to see if it holds.
I'm thinking of getting regular washers instead of the reduced OD ones for the middle 6 bolts of the plenum to spread out the stress in those areas.

I did to 5-6 ft-lb initially, then waited after 3 days of hard driving, rechecked and they were pretty much still at around 5-6 ft-lb. Just for safe measure, I reachecked all 18 bolts twice at around 6 ft-lb. Now i'm thinking I should have kept the torque wrench (i leased it from ace-auto for 6 bucks for 4 days...), rats
