cylinder head bolt torque

30 Oct 2007 02:26

I'm ready to bolt the head back on to my 86 Accord, but when consulting the
shop manual (original shop manual from Honda) I find information that may be
contradictory. On pages 6-2 and 6-16, the head bolts are referred to as 10
mm with 1.25 mm thread pitch, however I the bolts I removed are 11 mm with
1.5 mm thread pitch.

Given that the bolt size and thread are wrong in the manual, should I
believe that the torque specified is correct (22 then 49 ft-lb)? I would
think that the proper torque would be different for various bolt sizes and
particularly for a different thread pitch.
