    We used the term "infant mortality" in the aerospace industry. In particular electronic piece parts (at least back in the seventies) can exhibit a relative high failure rate early on. Then it settles down to a very low level, not rising again until end of life.

    For spacecraft that were designed for long life on orbit or years on interplanetary missions, most electronic parts went through a "burn-in" to weed out these early failures.

    Mechanical systems (engines and transmissions) and their individual components typically follow a similar pattern.

    If a camshaft gets though its first few minutes to few hours of operation without problems, then it will usually last a long time.

    Duke,

    I knew what you meant.
    Just trying to yank your chain a bit, or even get you to smile. Really.

        parkerizing is a extra cost option from some aftermarket cam grinders
        Another option is gas nitriding.
