2000 7.3 6speed burning oil
Ok, truck has a rebuilt engine in her with about 45k on engine. Has been using roughly 4 quarts of oil every 1200, to 1500 miles and smoke at idle a bluish whitish color and gets worse the longer it idles. When u take off after idling for a period of time truck will give out quit a bit of smoke till it clears up for the most part but still has a little bit all the time. I have been battling this issue for a long time and am sick and tired of it smoking all the time. Blow by seems very minimal to me no pressure and not a lot of steam. I can put a ping pong ball where oil filter cap goes and it just sits there and floats does not fly off. Oil filter cap same doesn't lift cap at all. Today I did a cold compression test. Truck has been sitting for about a week.

I just got done pulling all 8 of my hybrid 238% 100 injectors and. All look fine. Orings look good and in working order. All have copper washer and look good. I have check all injector bore and are clean. And no left over old copper washers. I had to such a lot of oil out of number 6 bore. All are clean now. What am I missing here. Does anyone have any ideas of why I am burning oil. Compression seems fine and blow by seems fine to me. What am I missing
I can add some pics of injectors if need to. Tired of buying oil and also oil seems very black and fuel like. Also o rings are Alliant brand.
I just took her on a 1400 mile trip to the keys of Florida and back and had to add a gallon of oil when got back home to get her back up to normal
