    I would use threadlock where the stud screws into the head.

    Well its all done and has covered around 100miles! It was tricky drilling the head, but managed it in the end. [:D]

    Funnily enough I have had exactly the same issue on my mk3 8v gti. set the timing up new belt on was on doing the tensioner nut to its torque spec and it then stripped almost identically. Few questions what helicoil set did you use I appreciate they need to be m10x1,5 but what about the length as there's a few options.
    Also did you use a right angle drill to drill the old threads out my only concern is the drill bit that comes with the kit will have to large a diameter for most right angle drills chucks. Am i correct in saying a m10x1.5 helicoil uses a 10.3mm Dia. drill bit. Finally just any advice or wisdom for doing the drilling and install plus has it held up long term.
    Thanks look forward to hearing back from you.
    Harry.

    I personally prefer the Wurth Timeserts.

    The kit is not cheap though (drill, countersink, tap and fitting tool).
