to be allowed to 'move'.
Clamping force is NOT the goal, but maintained 'gap' is
Curious why folks do NOT trust the designers who wrote the specification for the
torque on 'their' design
Know and understand that am in the vast minority because this is technology in
discussion...but...why don't you folks believe the instructions?
Would love to have some of you folks hands on build any engine without using
a torque wrench...components and machining costs out of your own pockets (your
skin in the game)
Doesn't matter small block, big block, diesel or even a 2 cycle chain saw ICE
Then ask it to go +100K miles under very hard conditions
Oh well...moving on...and get off this soap box...
