"bring engine up to normal working temperature, allow to cool, re-torque" is
the manner in which
the Volvo factory manual says their B27/28 engine is to be done(same motor
as in the Deloran). The
volvo heads were "angle torqued", rather neat I thought. Torque to 40-50
lbs(can't remember) and then
torque 114(can't remember exact number)degrees. I built this engine 120,000
miles ago, which is longer
than the original lasted. The original threw out its thrust washers(could
someone explain that for an auto?).
Sorry for the non-LBC content, but I covered two threads:)
