Just a guess, but it sounds like possably an oil leak around the oil pressure sensor or the infamous rear intake leak. I'm thinking the oil drips, or runs,onto the exhaust pipes on either side of the transmission while the car sets. Then when started, the pipes heat up, the resulting smoke follows the transmission tunnel to the rear of the engine and distributor area.

While your driving or using the car frequently, the oil is burned off as it drips, therefore does not accumulate.

As I said, Just a guess.

Good Luck.

With the engine off and cold, pressure test cooling system. This will quickly and easily tell you where your problem is.
