2003 4.0 burning oil

[Purplelongbox]

I have a 2003 with 4.0l v6 and its loosing about a quart of oil every 1,500 miles it's only has 94000 on it which is was to early for rings and for a he's gasket too. So I was was wondering maybe I had a faulty pcv valve? Idk what would cause that on these trucks

Also the truck still had plenty of power lights them up all the way through an intersection
