    I've never heard of re-torquing a cylinder head before. To me that
    would be an engineering issue. The o2 sensor on my Tiburon (97') has
    passed the 190,000 mark. Like any electrical part, you never know
    when it's going to go. Much depends on how well you take care of your
    car. What kind of fuel, regular maintainance, oil changes.

    All in all the 97' has been a great car. Now it is starting to show
    that it has some miles on it. It's being taken in to the shop to have
    its first replacement clutch installed. 190,000+ miles is something I
    would never have expected out of any car, clutch wise that is.

    It's questionable whether you'd prevent any failures by doing this. There
    is no official recommendation to do so. On the other hand, if it's your
    own labor and the bolts are readily present under the valve cover, then
    there's little to lose, either.

    our cars starting to show signs of needing a clutch job , once its warmed up
    it vibrates on acceleration, and at high speeds you can smell the clutch..
    we have 155 000 kms on our 99 accent

    well if its not recommeded why bother..
    just puzzles me why a tech would suggest it in the first place..

  10. I've done it on a few cars in the past, along with valve adjustments and
    other things that newer engines apparently don't need. However, youre
    friend's head gasket failure could well have been caused by loose or
    unevenly torqued head bolts. As long as it's done properly, I don't see
    how re-torquing the head bolts could cause a problem. Perhaps just
    checking them once in a (great) while would be enough to ensure that you
    never have a problem with them loosening.

    I'm thinking Ford had a prolem with them stretching 10 or 15 years
    ago. I could be all wet but I think it was a deal around aluminum
    heads on cast iron blocks that led to stretching head bolts that
    eventually failed or let the gasket fail resulting in antifreeze and
    engine oil getting together. At the time they were reccomending
    retorquing around 60 or 80,000. Once those ideas get started I think
    they tend to spread and become one of those hoary old bits of wisdom.
