    A few days ago, I noticed a soft but noticeable clicking sound coming
    from my 1998 S70 T5. The clicking sound gets faster when I accelerate
    while in park, and I assume it does so when I'm driving.

    Any ideas on what this could be? I have 109K miles, and my timing belt
    and pulley were replaced at 70k.

    An exhaust system leak, loose valve lifter or serpentine belt with a
    ragged edge can make a ticking sound that would increase as the engine
    RPM's are increased.

    exhaust leaks get louder when accelerating and most exhaust leaks (depends
    on just where they are) get quieter within about one minute of starting the

    Yes, I agree it would be the first thing to check for. And they
    can be difficult to track down.

    BTW, Google seems to have died the past 2 days. Message updates are
    not showing.
