Tue, 27 September 2005 23:26 clean your threads, lubricate them, make sure theres no dust around, and use a high quality torque wrench... as there is no way you can measure the stretch of a main cap bolt. A rod bolt is possible as they use a nut on the end... but how far will the bolts stretch at the required torque?? this is a complex mathematical equation dependant on impurities in the material of the bolt, the heat of the bolts, and how much the head squashes on the con-rod (among other things)... so it is also innacurate. Personally i would just take my time to make sure those threads are perfect (mostly just for the main bearing threads in the block, because all your bolts and nuts will be new, and should have high precision threads). This also applies for your head studs. Cheers, Owen (2 months away from being a qualified engineer... about time!!) EDIT: Dont forget to use fairly new, high quality sockets, as they will also stretch and could cause further innacuracy [Updated on: Tue, 27 September 2005 23:27] [Report message to a moderator]
