    The gasket compresses, effectively leaving the bolts loose and the gasket un clamped.

    You need to remedy this situation, otherwise you run a very real risk of blowing the head gasket.

    1st service also includes rocker inspection too. Easy to do while the valve cover is off.

    I have more Q's
    1) Where/How does one apply the "Extreme Pressure Lube"
    2) Is the Head Cover Gasket reusable?

    1 - This is fastener assembly lube, you can get it online.
    2 - Mine was reusable, but I wouldn't reuse it more that once.

    With regards to the "How" , Do you remove the fastener completely, coat in lube and torque as recommended?
    Only asking as I've never used this before

    If I were rebuilding the engine and replacing the head I would cover the bolt threads with a light coating.
    But if just re-torquing the head, I wouldn't bother.
    The fastener lube is designed to eliminate friction between the bolt threads so that the correct tension can be reached in the threads to achieve an accurate final torque.

    I have a downloaded version. It says
    "Tighten head and barrel bolts in sequence from one to twenty to torques detailed below (shown in detail in this chapter, section: 4.7.7)
    Torque: Barrel Bolts – 25Nm
    Torque: Head Bolts – 30Nm / 60Nm (Refer to 4.7.7)
    Cylinder Head Bolts"

    But my downloaded version doesn't have a section 4.7.7 for some reason

    Check section 5.7 onwards, that seems to have the diagrams
