<All> Head bolt torque tips



<<Hey, group, I was just cleaning up some papers last weekend and found 
an engine building booklet printed by Hot Rod magazine.  .......

1)  When torquing head bolts, always use a washer under the bolt, 
even on cast iron heads.  Also, put a drop or two of oil between the 
washer and the bolt head.  This lessens friction and ensures a more 
accurate reading from the wrench.>>
This depends on the recommendation of the manufacturer.  Some specify lubing
the threads, some require that "loctite" be used, others require other stuff.

<<2)  AFter torquing all the head bolts, let them sit for an hour or 
so, then back each bolt off about 1/4 turn, and re-torque.  If you 
mark each bolt relative to the head, you will find the bolts turn 
farther the second time it's tightened to the same torque spec.  This 
evidently "overcomes the breakaway torque" required to reach
the final torque setting the first time.>>
This is for cast iron blocks and cast iron heads with old style head gaskets.
Aluminum (aluminium) heads and/or newer gaskets require different procedures.
Great method for older Chevies and Fords, but this is not applicable to Audis.

     Later.
