You might chek the spark plugs to see if one or all cylinders have oily deposits on the plugs.
While the plugs are out it would be worthwhile to do a compression test. This will tell you if you have bad piston rings, cracked heads or blown gasket, or my guess... worn valve guides/seals.
I would guess valve guides or seals since ... when it sits, the oil in the head can leak past the guides and down to pool in the cylinder. When you fire it up you would get white smoke. Piston rings usually smoke more often and longer.
Good Luck,

Pure white smoke, have you smelled it?
I am thinking it might just be steam because the weep hole is plugged up on the muffler. Once the engine has cooled, the water is running back towards the muffler and not exiting the weep hole and is burning off once the cat. converter and the rest of the exhaust reaches 300+ degrees.
Once the car cools, after the 8 hours, jack the car up and see if any fluid comes out the tail pipe.

Valve Seals.
