I have a problem and hope yall can help me out with this 7.3 powerstroke diesel truck. I was wanting to know how can you tell if a diesel is burning oil from the crankcase. The truck engine was rebuilt and all internals was replaced and the truck didnt use no oil till I replaced the HPOP. The truck will either lose or burn one quart of oil every 83 miles and the truck will start in the coldest weather and it dont smoke and it runs great with all kinds of power. This is my first diesel truck and needing to know where I need to start at trying to find out where the oil is going to. I am also new to this site and hopefully get enough knowledge form this site to help other people out. The old gassers are easy to figure out where oil is going but this has me puzzled. I am needing to know where to go from here. Thanks:nail:
