I'm in the process of reassembling the engine of my S350 after replacing the #1 connecting rod. The manual states a torque of 90Nm for the connecting rod bolts. I am finding that they peak at about 70-73Nm for a full turn. It just does not feel right that I should take them all the way to 90Nm. My instinct says to leave them alone after 1/2 - 3/4 turn at a steady 70Nm. Should I be measuring bolt stretch instead? I don't see anything in the manual about that, however...
Any thoughts appreciated. -Dave Walton
