So this started happening about two days ago. I got in my car started it and turned the ac on and instantly was overwhelmed with the smell of burnt oil coming through the vents. I have spent the last 3 days now searching all over the forums as to what could be the cause. Last oil change was 3 weeks ago. Its a 2014 challenger rt plus with 35000 miles on it. I've seen some threads stating that a catch can will help reduce blow back and thus possibly eliminating the problem but I've yet to see an update on whether the issue was resolved. I checked under the hood as well and didn't see any oil build up along the VC. Any help would be greatly appreciated.
