Pull the intercooler hose off of the intercooler and see if you have signs of blowby in there. It could be as simple as you needing a new turbo, without getting into the engine itself. My buddy has an 04 dmax LLY that was "losing oil", so I went under and yanked the boot off and she was dripping oil pretty good. New turbo and has been holding oil ever since. No more blue-ish smoke on start up either..
