nasty noise from 106

First post here so hello all.

I bought a 1992 106XN 1.0 with 92k on the clock a couple of weeks ago
and after four or five hundred miles I'm becoming more and more aware of
a nasty sound from somewhere at the front of the car. At first I
thought it was a wheel bearing but I now think it maybe be something a
little more fatal.

There's what may be desribed as a grindy / squeaky noise that is
dependant on the revs. It is at its loudest when I lift off the
accelerator and the car is coasting in gear; for instance going down
hill or slowing on a motorway sliproad. To my untrained ear it sounds
like the gearbox or somewhere in the bottom end of the engine that's at
fault. Does anyone have an opinion on what would be most likely to be
could be causing this?

Any ideas?

Thanks.

Could be a cam tensioner roller.

 

Check the driveshafts......

Thanks for your replies people, I'll brave the cold on my day off from
work tomorrow, stick a jack under the car and give things a shake to see
what, if anything, moves in the driveshaft area. It's certainly not
showing signs that I would recognise as a worn CV joint, ie, clunking
when turning on full lock. As for the cam tensioner theory, that sounds
possible too. It sounds like a worn bearing type noise but not really in
the wheel area.

Apart from the problem I'm talking about I'm very happy with my little
106, particularly as it cost me all of £120. It seems to run quite
well otherwise. A nice change from the various Saabs I've been driving
for the last ten years or so. Certainly a lot more economical.

Thanks again.

Gerry.

 

cambelt tensioner is my guess, replaced a few of these over the years,
if the noise is affected by engine speed and is still present when car is
stationarry then disregard the driveshafts despite there notority for wear.
isolate the alternator bearings and alternator belt tensioner by removing
the belt and running the engine.
