    smear with engine oil both bolts and washers.

    First torque to all headbolts to 30Nm, in cross pattern, then torque them to 50Nm.
    Done!

    Special Tool for one bolt? - measured by degrees not NM?

    A normal socket will reach three of the head bolts but one bolt will require a special torque wrench adapter.

    The rod bolts are torqued with both N/mm and with an angle gauge, but the head bolts are 30 + 50N/mm as Danneh
