First of yes I know this isn’t a cobalt but this does use the same chassis and engine and the HHR subreddit is locked so here I am!

I’ve noticed that after I let my car idle for any more then around 5 minuets that when when I began driving again it smokes a lot out of the tail pipe with a dark grey sooty smoke.

I’m not completely surprised if my engine is simply worn out or damaged but I do have a few errors that I’ve scanned from the OBD system that indicate fault from PCV and other emissions related issues (those ones I believe are due to a bad fuel cap) but is this normal for a HHR with 242200 miles and if it’s possible is there a way I could mitigate the oil consumption or fix it through and through

I think that this air filter was original to my car from factory
