Thought I'd make a new thread so this could be seen by more people. I had a theory that the following could work and it did for me. Hopefully this can work for others that can't afford to get it professionally addressed.
As some know, the PCV orifice gets clogged up with sludge/ect due to bad design (orifice being too small) which causes too much pressure in the crankcase and oil gets sucked in via PCV hose to the air cleaner outlet duct. Long story short, I did the following which so far has completely fixed my issue with oil being consumed at the rate of about 1/2 to 1 quart every 500/600 miles.
1. Get yourself a vented oil cap that can prevent your rear main going out due to all the pressure buildup as a safety measure. It will say that it does not fit but it does for the 2.4L Ecotec
ACDelco FC219
2. Add Seafoam High Mileage in the gas, when about 100 miles remaining on the tank I added the directed amount into the oil. I then added a small amount directly into the PCV hose port (not the outlet duct side) Why not right? 😆 You only want to run with this in your oil for about 100 miles before getting a oil change done. This greatly helped clean out a bunch of sludge/ect from the oil.
3. Use CRC GDI Cleaner after the above step but within the remaining 100 miles before the oil change. You can simply loosen the Airbox connector, insert the CRC tube toward the throttle body, retighten and follow the directions on the bottle. Make sure you spray it upside down as it not recommended to spray sideways + no space to spray it upright.

4. Get a oil change/do it yourself.. I went with ACDelco full synthetic..
So as mentioned before I would lose about half quart to a full quart of oil every 500/600 miles. After the above steps I am currently at about 1,300 miles with no oil loss.
Let me know if this has helped you! I'll post a update when I hit higher mileage
