Ok, I will try and make this short... Maybe someone can point me in the right direction or to some posts on this topic. 2011 LTZ with 104,000 miles. Last month I started to have the smoke on cold start issue. It only happens after 100 plus mile trips. The first time it happened was after a 16 hr trip. I checked the oil level an it was extremely low... Like nothing on the dipstick. I added oil and no smoke. Last week I changed the oil before heading out on another trip (probably 500 miles) so I could gage the oil consumption more closely. After the trip the oil level was only about 1/4 inch on the dipstick. Coolant level is not dropping, gauges are fine and the truck is running good. The smoke it white with a hint of blue. This is obviously not good! Where should I start? Disable the AFM? Valve covers? Not sure what year GM fixed that issue. Thanks!
