This is uncommon for the 1.8.

Given the P0171 code (as well as the P2270) and blue smoke, I believe you still have an issue with the PCV integrated into the valve cover (yes, this is for 1.8's too, but far less common of an issue).

I would take it back to the shop where the valve cover was replaced and have them test it. Typical PCV checks include pulling out the dipstick or oil cap at idle - smoke should NOT puff out the opening; this indicates positive crankcase pressure that the PCV system SHOULD be re-routing into the intake manifold.

The P0324...I'm not sure. It may be throwing knock codes because it's running lean.

The person that changed the valve cover wasn’t from a shop. It was my aunts mechanic that came to my house . I’d rather not take it back to him bcuz he told me that a bad o2 sensor wouldn’t turn my CEL , which I feel and have been told multiple times that it would. And the only reason I allowed him to fix was because firestone wanted over $900 for valve cover , spark plugs and ignition coil . I have a shop that will check everything and diagnosis what they believe is wrong .

I'd double-check what engine you have. IIRC, the 1.4 Turbo was an option for the LS. That's make a big difference in the advice. What you're describing is pretty common for the 1.4, but very rare for the 1.8.

Where is the oil filler cap? Is it on the side of the engine toward the radiator, or toward the passenger compartment?

No it’s def a 1.8. The oil cap is in the top right corner . I’ve attached a picture of what mine looks like . I’ve realized that these issues are common with the 1.4 , and haven’t found many threads about issues with the 1.8.

Hey just giving an update for those that have the 1.8L engine and may have the same issues . This issue still was my valve cover and PCV. The cover had to be replaced again . This fixed the oil leak and the lean code. I also had another leak and my oil filter gasket had to be changed as well.
