Sounds like massive blowby getting past your rings. Could be your pcv system isn't working.

Even if PCV isnt working, you have to have some pretty serious blowby to blow a lot of oil out the dipstick.

Blowby is combustion gasses blowing past the piston rings into the crankcase due to wear or stuck/broken rings.
The PCV (positive crankcase ventilation) system draws air through the crankcase through a PCV check valve into the intake manifold. Fresh air enters the crankcase through a breather filter. If any of this gets clogged, pressure can build in the crankcase and could force oil out the dipstick.
The Chilton and Haynes manuals explain this thoroughly and show the component locations. Good luck.
