Rain finally stopped so car came out of garage. Pushed pedal a few times. 50% of the time, some noise was heard. Shot some WD 40 on the pedal shaft and worked the clutch a few times. Noise seems to have stopped. For over 20 years, the clutch has been operating normally but pedal very stiff compared to Alfa. Or maybe I'm getting weaker. Since I haven't driven another TR6, I don't know how stiff the pedal should be but it catches low (Alfa catches high) and doesn't show any signs of slipping or strange noises. I think it was replaced by PO.
