Cylinder head bolts are not torqued and don't have a specific torque value? The bolts are just turn until snug , then tightened like 3, 6, 9 12... o' clock or like you suggested 45, 90, 180, 360.... deg. turns, evenly all across the head? ...and by the way, where can I get those socket bits for the star head bolts, and what is the technical name for it or MB part#? |
All of your aforementioned concerns are valid risks. You need to have a feel for the bolt........know when it's yielding.........if you push it beyond it's limit........you will snap it. I'd attempt to tighten all of the bolts at the rear of the head by 1/8 turn........if they move at all.
They are torqued to a spec and then turned to an angle. This is done in steps.
The socket bit is a "12 point" or a "triple square". It's available at most auto parts stores.
