00 Expedition Smoking

Seeing Smoke from Tailpipe during startup. usually in the morning or after the vehicle sits overnight.
Does anyone have have a clue to what could be causing this?
Everything seems to fine. Two mechanics have checked the vehicle and were unable to detect a problem.

:banghead:

If its cold then it is nromal for the car to smoke a bit cause the engine is cold. What color is the smoke?

This is definitely not the cold, morning condensation burn off i am familiar with.
The Smoke is a denser White or Bluish in color and does not dissipate as quickly as condensation.

Could it be "drain down"? Does this sort of thing start happening as a vehicle begins to show it's age?

Seeing a puff of Bluish/White Smoke from tailpipe during startups.
usually in the morning or after the vehicle sits for awhile. Smells something like burnt plastic. Two mechanics have checked the vehicle and were unable to detect a problem. Everything appears to be fine after engine has warmed up a bit.
