Oil issues

[tommy53002]

So it's consuming 3 quarts every 300 miles? That is a lot. I don't know how long that could limp along.
Swap in a rebuilt long block and be done with it for another 200k...

No, I added 3 quarts in the last 740 miles.

Karl pretty much covered everything as far as rebuild options go. If you're attached to your rig and plan on building it over time, an LS swap might be a good choice... $750~ 5.3 with accessories and ecm is pretty standard going rate at yards.

You might try a quart of this with your next oil change while you're limping it along. http://lucasoil.com/products/engine-...oil-stabilizer (I use it in all of my vehicles and race cars, it works...)
