A puff of blue smoke on startup, bad intake valve guides. Smoke on acceleration, bad rings.

The best cure may be to drive it. Sometimes old rings will come back to life after you drive a car a few hundred, or a few thousand miles. You have to get the engine thoroughly warmed up short trips won't do much.Add some Rislone or Bardahl and go for a drive.

Or you may need a ring and valve job. This was a standard service procedure on prewar cars. Believe it or not, they usually needed a ring and valve job after 20,000 to 30,000 miles.

A compression test will tell you a lot. If compression is low retest after squirting a little oil in the cylinder. If it comes up, the rings are bad.
