I have done a compression test and the numbers were fine in cylinders 1,2,4. #3 was a tad low, but nothing insane. I guess that could be something that's happening, but I'm not burning oil visibly, it doesn't smell. Occasionally when it's really cold (Below 40) and I start it, the idle will hang at 3000+ RPM on cold start and it will smoke out the exhaust, but I think that's because it's sucking oil through the PCV because of the insane idle.
Other than that, you would never be able to notice I was losing oil except for the valves start clattering every 1000 miles and I add oil. I'm just not sure how that would cause an idle issue when it's cold outside? (Engine temp does not affect this).
I need to do a leakdown, but I don't have access to any of the stuff required.
Edit: These are the numbers from last year. Not too great.
