Unfortunately there's been several that developed this problem and blown.
There's been several suggestions on what to do.
There's also some debate as to what exactly causes it, some say it's related to the PCV failing, oters say it's from the piston ring design, plus other thoughts too.
The Isuzu Axiom engine (from '04-?) is supposed to be an easy replacement and does not have the oil consumption issue that many of ours did/do. I can recall one guy did the swap (iamironman). An Axiom engine should be pretty easy to find in a salvage yard to replace yours.
He's since sold his but here's his info on it:

Several others have replaced their engine, I'm sure some of them will chime in here.
Here's a post with lots of discussion about the oil issue, and theories on what causes it.
