I am posting this for a buddy of mine to see what you folks have to say. The vehicle is 2006 z71 x-cab 5.3l. He is going through about a quart and half between oil changes. He has had it once for warranty but now warranty is gone and its still doing it. What they did to supposedly fix it was to pull heads replace valves, valve seals and stems, check for head warp. Basically a complete head job minus replacing the springs. It lasted for about two oil changes and its back to drinking the oil. As of right now there is no oil in the coolant its not leaking. So my question to you all is where in the world could it be going and what might be causing that much oil loss between changes.
All help is greatly appreciated
