Souunds like the car wasn't driven a lot and something taht had worked
loose reseated itself...?

What are you using for oil? My Supra would smoke after sitting for a
couple days, then I started using 'high mileage' oil, and I can let it sit
for a week without the ol' blue cloud.

Ouch, the only time my Supra used any oil it had a vacuum leak from a bad PCV rubber hose
on the valve cover. Don't ask me why it did that (maybe positive crankcase pressure) but it
has another 50,000 miles on it now and only gets 1/2 quart low or so between oil changes @10,000 miles.
