Thanks for the information, you'd think the service tech would have thought of that, but he only scanned it, looked for visible leaks and a drive around town. Of course no blue smoke puffs, I'll relay this next week when I visit before my warranty runs out.

Haven't seen any noticeable oil loss, it's a 5.3

Correct oil, filter and level good.

Sorry I don't know how or if I can move this to the correct spot.

Hey guy, did a recent oil change on my 2919, shortly afterwards I started seeing blue puffs of smoke usually at hyw speed. This only happens periodically, have taken to dealer, they scanned and test drove, saw no issues. Anyone have this experience?
