I have a 2019 with the 5.7L and 143K miles. Over the years, I have seen occasional puffs of blue smoke on startup. Nothing too crazy. However, the last three mornings on initial startup after sitting all night, I have had excessive amounts of blue smoke from both tail pipes. See attached photos. It clears up after a few seconds and no smoke while driving. I'm assuming valve seals? Just odd how it pretty much happened overnight. Am I correct in assuming valve seals or is there something more serious going on here?
