I have been chasing a severe oil burning problem for a while now, been going through about 1qt of oil per day, 5-6qts per tank of fuel, and it doesnt leak a drop.
I have changed all 8 injectors & orings, sent them out to be flow tested, found a few more that had gone bad, and Im STILL burning oil. Also changed a bunch of other things, including a new turbo.
I have no Idea whats wrong with my truck, however Im fairly certain its just severe blowby at this point. I was planning on changing out my valve stem seals and seeing if that helps, until my truck started making grinding sounds comming from the clutch area.
I am also dead certain I have a high pressure oil leak somewhere because my engine still stalls from time to time.
If I were you, I would be dead certain its an Injector! Do a Contribution and a buzz test with a Rotunda Scanner or Auto Enginuity, and make sure its a bad injector. Otherwise you might just be wasting your time & money changing injectors all the time like I have.
I dont want to steer you in the wrong direction, and there are alot of other members here that know MUCH more than I do, so don't take my word for it.
If you do end up buying a new injector, I get mine from riffraff
They are NEW out of the box, and not rebuilt. Seem to work great, alittle hard to thread the oil spout back on because threads havent been used yet, however they work GREAT! All of my injectors are these aside from 3, dont forget, if you change number 8 you will need a "8LL" injector, and not an "AD"
