My boss has a 2007 Chevy Avalanche with the 5.3 -
His started smoking real bad on start up.
I sent him the bulletin on oil consumption and smoke , link below , he replaced both valve covers and his issue went away.
He's been using bulk Jiffy lube oil for it's whole life , 5w30 and it has over 150K on it.
