I have a 1994 GMC Sonoma with the 4.3L V6, 104K miles on the engine. The oil had just been changed when I purchased the vehicle. I dumped in a bottle of Auto-Rx. replaced the filter at 1500 miles into the treatment. The filter seemed pretty clean other than some metal flakes. What would cause this (bearing wear)? What are the mechanical signs of bearing wear?
(as a side note, I just finished the Auto-Rx treatment this evening.I changed the oil and started the rinse phase. Truck seemed to run much smoother. I will cut this filter open and examine it after the rinse phase.)
