started having the elusive oil burning issue with my 2010 Chevy Crew Cab z71 5.3 aluminum block with the 6 speed and AFM. A fouled no 1 cyclinder spark plug left me on the side of the road at 42,000 miles. did oil consumption test and was "within spec" at 1.5 quarts low during alotted time. Raised hell and am currently getting valve cover, oil defelctor - blah blah blah done today. ive read just about every post on every gm forum on this but nothing has been stated withing the past 6 mos on actually fixing the issues. i know most ppl are having the rings/pistons changes. but i have really been thinking about trading for a 2013 or something. just worried what problems will happen above 100K miles when the warranty is out.
