hey JB, my 01 v70 W/134,000 mi. sounds like it is making the same noise. At first i thought it was the valves, or a bad bearing on the main drive belt adjuster pully. I replaced the pully with no change. I now think that the engine is pinging under any load, the noise seems to be the same hot or cold, and i mixed in 1/2 a tank of 93 octane and didnt notice any improvement. I first noticed this after having the transmisson serviced, at a local trans shop. Is there a knock sensor and if so where, and any way to test. thanks to all for any ideas. BOB D Also there are no lights on or error codes
