Dennis,

Bluish smoke might mean an oil control ring problem.  Weak oil control rings
would cause the catalytic convertor to heat up until you could literally toast
bread on it.  At night, it would glow cherry red.  Perhaps, some excess
oil/fuel ignited in the convertor.  In the old days, whenever life was meant to be
fun, you could turn off the ignition while coasting down a hill and build up
enough fuel in the exhaust system to male one hell of a backfire.
