To get accurate torque values, friction must be held to a minimum. Lubricating the threads aids this. Bolts that go into water jackets should also have thread sealant on them. To me, it has always seemed like a bit of an oxymoron to lubricate the threads and then also try to seal them.
The now more used torque-to-yield specifications keep inaccurate torque readings from being a factor in getting proper clamping forces. They rely on a predictable amount of bolt stretch.Rob B 95Z A4 Tech Page (Part numbers / locations, how to's, schematics, DTC's...) Home Page - shbox.com
