A engine sound? is it bad? S90-V90

posted by  someone claiming to be Jay on  Sun Jul 27 15:36 CST 2003 [RELATED]

I have a newly purchased 97 s90 with 52K on it. During
a drive today, a sound has developed from the engine area.
It started after I was driving for quite some time so I
dont think its the hydrolic valve warm up issue. It
sounds like a whirling/very muddled tapping sound almost
like belt noise but louder. Is it something to worry about?
The noise also accelerates when pressing the gas.

Anyone have any ideas? Thanks.

    Have a Volvo shop carefuly check the timing belt bearing (and pulley) checked as soon as possible and replaced if needed. Mine went bad at a bit over 60K miles on the car. Had I not replaced that bearing on the spot, it could have torn the timing belt and the engine would have self destructed.

      You guys think it is the timing belt making all
      the racket? even if it was fine the next day?
      I just want to make sure, cause I live way too
      far away from a Volvo shop.

      It was hard to say, but it sounded like it was
      from the rear of the engine.

    A More logical Explaination S90-V90

    Check the pullies and berings on the timing belt. There should be two of them, I am betting its the bottom one. Once you open the black cover that is covering the belt look at the bottom are there little balls of metal? If so Do not drive your car anywhere. this means that you need a new timing belt pullie. I hope this helps.\

    The belts I know of in the car are the timing belt and
    the accessory belt (which seems to service everything with
    just one long belt) Is there another one hidden somewhere?
    (its a pretty tight compartment) I checked the accessory
    belt and seems alright except for this brown dust on it
    but that is not concerning me much. This morning there
    was no trace of that sound but I fear that it will return.
    Because it is gone again, does that meen its less of a
    problem than if i heard it all the time?

    Thanks

    Also - It happened while driving and in park.

      The timing belt is your biggest concern and since it is close to changing @70K, I'd give it quick visual inspection. It's located under the plastic belt cover on the front of the engine block. If you don't feel comfortable in doing this, I'd take it to a Volvo shop to get a peek. It will require a 30K tune-up soon, so there's a laundry list of recommended things to do then.... plugs, filters, change to synthetic oil, coolant + thermostat, brake fluid, and perhaps change to synthetic ATF.

    It might be the air pump. It is really loud compared to other cars, but I don't think it would change with speed. The first time my wife heard it she was certain something came loose and was "wherring around under the hood."

    Has the car been thoroughly checked out, including a visual inspection of both belts? Everything else is secondary.
