Most likely cause are your engine's valve seals or the piston rings. Do a Google search of this newsgroup for a procedure to "unstick" your rings. Some have reported limited success in significantly reducing oil consumption. The overnight procedure seemed pretty simple and not very costly. It seemed worth trying first before you invest major dollars in rebuilding the engine or have to dump the vehicle.

Good luck (and post your results so that others can benefit from your experience.)

If you havne't tried it already, change your pcv valve and see if that helps. If not, got to the ring sticking aid. MR
