Just got the car back from a radiator installation (1993 960 wagon, 2.9L I-6)
Well we poped the hood, and we heard what sounded like a clicking noise.... Usually it goes away, today it didn't.... And you can hear it when the engine revvs up, my dad thinks the valves are clattering, and thinks they need to be adjusted... I told him they are self adjusting, isn't this correct? Otherwise the car runs great, what do you think is the proplem, it gets regularly driven and allowed to properly warm up, and it has recently been on a long highway trip. The service/tuneup for 145K Kms was done only a few weeks ago.
