This vibration damper is prone to fail. The most harmfull situation is to twist only. There is a inner stub, mounted on the crank, and a outer ring. You will see the tdc marks etc on this. Between both is a ring made of rubber. This will crack and lose parts. Sometimes the rubber start to move out. Often to the rear side. You will listen to a squeeky sound. The rubber will rubb on the cover of the timing belt. If the pulley is wabbeling or moving to the side or the marks are not really on tdc: change it as fast as possible!!!!
If the pulley got lost his outer ring the damage will be hughe. The original ones last about 200 000 miles and around 20 years. The aftermarket max 100 000 miles and between 5 to 10 years only. Idiot will renew the seals and use the old broken pulley again.
Idiots will change the timing belt without having a closer look to the pulley and wonder about the engine after. Running bad or even won't start. Timing belt out of position. I bought good car cheap in the past because of this "tune" ;-)
Do a full stage 0 tune if you buy the car.
Be a Happy volvo owner in the future, regards, Kay
