Engine Burning Oil Problems of Subaru Crosstrek

I have experienced rough idling with my 2014 Crosstrek limited for about a year. During this time my check oil light has come on twice. I brought my car into the dealership in fayetteville, ar where they began the oil consumption test process. Thus far the dealership has flushed my coolant and oil and replacing o-rings and valves, replaced more o-rings and my ac compressor, and completed four oil consumption tests each time I drove 1,200 miles and consumed 8oz oil (10. 1oz is considered failing). My car continues to rough idle to the point that I cannot let it idle inside the garage without shaking the walls inside the house. The rough idle happens all the time, when I first start the car, after I have driven for a while, and during routine trips around town, anytime the car is idling. The dealership has advised me that rough idle and oil consumption is normal with Crosstreks and nothing shows on the computer scanner. They refuse to do a mechanical check to further diagnose the issue.

Excessive oil consumption. Oil lights comes on every 1000 miles.

The engine burns oil too fast. Every 800 to 1000 miles the car requires 1or 2 quarts of oil.

Takata recall for the past year I have been checking my motor oil and refilling as needed. Learning to be a car mechanic is one of my hobbies that I like to do. In doing so, I always check my car and make sure its up and running with no issues. I have constantly notice that there was some oil under the engine whether old or fresh. Then just recently I went to my local Subaru dealership to finally get to the bottom of it. As a result I learned that the cam box seal is leaking. I then did my research on it and found out that it's a common issue among other Subaru owners and that other car brand uses gaskets in which it lasts longer. In my view, other owners may not know how or when to check under their car for these kind of issues and this can lead to the engine not having enough oil to burn and breaking down or similar situations. It may not be a short term effect but if it can be prevented it should be.
