Why don't you consider doing the Axiom engine swap that iamironman did?
You get a newer engine without the oil use problems, sounds like it would run you somwhere between 2800 and 4000, depending on how much you paid for the Axiom engine.

Clipping from his thread:
if anyone blows a VX engine... go get a used '02 Axiom engine to replace it!! they can be had from about $1200 up to $2500... I got lucky and paid $500 for mine... but after all incidentals, fluids, gaskets, yada,yada, cost me $1100. R&R of engine(s): $1600 (paid for the extra time to work with the ECM's seperately so that doesn't count for the R&R)
