motor burning oil

If no obvious leaking anywhere, then two things I would check. First see if there is oil in the exhaust that may be coming from turbo. Also, run a quick oil sample at a local Speedco or other shop that can do it, and see what the sample shows. If there is a lot of leaking around rings and such, then there will be a monster load of soot showing up in the oil sample. That would explain any oil burning also.

 

overheated onece it burns oil. usually bad piston rings, sometimes liners.

To be sure open oil filling neck and check for crankcase pressure...

 

I ran into this ! Mine was covered by warranty but i hate to tell you the cylinders are shot because of all the egr soot ! Dealer replaced 6 cylinder kits wouldnt replace the head but i since have all the guides was wore and badly carboned up ! If you are keeping the egr system i would at least put a bypass filter such as a spinner ii i have installed one on mine and oil samples are alot better it takes alot of the soot out of the oil that has wore the cylinders out! I have deleted the egr out of mine best move i have made to help the engine last longer.
