I've been driving the Miata fairly regularly the 10 minutes to work and back. High-rpm puffs seem to be diminishing. Maybe the oil control rings are loosening up.
On the other hand, I've started to hear some squeaks and screeches from the clutch. I've always heard a bit of pilot bearing rumble (goes away when clutch is depressed), but it started with a bit of a dry squeak while the clutch was being depressed. I've read that this involves a loss of lubricant of the shift shaft and isn't catastrophic. On the other hand, I heard a much more obnoxious screetch the other day that wasn't tied as directly to clutch in or out. We sat, I think in neutral, clutch out, at a traffic light when a screetch started. A touch of gas made it go up and down and then it quit. Pilot bearing finally going?
