Hi,

No, the torque spec is 22 + 2 Ft. Lbs. First torque to 22 and then 24, that's straight from the Service Notes...

I have my eye on a $229 Snap-on torque wrench. Perhaps if I purchase it, I'll be able to sleep better (on the couch, however).

Hi,

Snap On is good stuff, but if you go with a top-end Craftsman, you get free recalibration (not certain Snap On offers this). That can be important because a recent SAE study of 1000 random quick release (Click Type) Torque Wrenches showed them to be as much as 50% inaccurate. So instead of applying 24 Ft. Lbs., you could be applying as little as 12 or as much as 48 ft.lbs.

The most accurate, and those used by professional engine builders, are the Beam Type. I have both and can check my quick release against the Beam Type for a fair accuracy check...
