this is hot after a 40mile test drive after I replaced tenser and idler pulleys and put on a new Short Belt.
prior to this I'd hear a ticking noise that went away once warm that I thought was a pulley going out, since it was loudest from passenger side of engine, and pulleys felt loose to hand.
Seems like sound has been getting steady louder. Screwdriver-stethoscope on valve cover sounds OK, and no nasty noises. Seems like its EXTERNAL almost.
I think I'll take to highly rated SAAB shop, but I'm interested to hear any ideas.
Got car from curb-stoner who got it from Donation Auction. It had been sitting cold for few days (spiderwebs) when I first started and this sound was not there, and IIRC not there for first 1-2000 miles I put on it.
130K total granny miles on car.
Could this be an ACCESSORY driven by the belt making this noise?
Is it possible to stop the belt by cranking the tenser but leaving belt in place?
