    Angry wrx burning alot of oil need help

    i have a 03 wrx. Just rebuilt the engine, new crank new rings new bearings, all new gaskets and seals, i rebuilt the turbo, have all head work done and the car is burning oil like crazy. didnt at first but with like 30 miles on the rebuild all of a sudden it started. Its burning alot like 3 quarts every 20 miles. as soon as you start it up its a smoke show. Its not the turbo, or valve seals. Im thinking its either piston rings are not seated or a vacuum line is messed up? Ive searched all threads. And im going to school for automotive too.
    Please let me know if anyone has any ideas what it is or suggestions!
    Thanks!

    I wish I knew and could help you but def not qualified but I want to know when you know because thats weird that compression is all the same on all cylinders. I would think the only thing it could be was the rings. Unless oil is getting into the intake system because the turbo is messed up and oil is getting by. Im interested to hear the final results. I know when turbos go out in our semi's they smoke like a *****.

    Id take it back to whoever rebuilt the motor cause obviously whoever did the job messed up somewhere... and did you do the break in proceedure? Ie keeping the speeds below 55 change the oil after the first 1k miles drive slow with little to no boost? Also id probally have to guess it has something to do with the piston rings if they are not set to the right bore then your oil is gonna go up past the heads and end up burning away...

    Since your compression is in check, I'm leaning towards a head problem, either with the valves, or a head gasket. It's obviously hemorrhaging oil into the combustion chambers.

    Have you taken off the intercooler to check to make sure the turbo isn't blowing oil into the intake charge?

    I rebuilt the motor and everything is the way it should be. And the motor has 50 miles on it. havent taken it past 2500 rpms. I just took the heads and every thing turned out fine and there is no blow by on the piston rings.

    If your turbo is healthy, odds are your oil rings are incorrect, or installed incorrectly.
