    Is my turbo burning oil?

    I see smoke coming out of the hood and I smell the oil.
    Several mechanics (non Subaru specialists) have not found any leaks.
    It burns probably a quart every 1000 miles.

    I have kept on top of my oil -- but my local Subaru dealer won't even look at it without spending $200. Unfortunately, I cannot go taking apart my engine myself (for various reasons) to find the cause.
    When I try to pin-point the smoke it "seems" like it comes from the turbo area, but it could be coming anywhere around the engine....


    How can I pin-point the issue and get it taken care of?
    Are there further steps I can take start ruling things out and narrowing in on the cause?

    2002 Sedan with almost 100k and I have been using Mobil 1 synthetic.
    Stage 2 Cobb (turboback w/ tuned ECU)
    I got it used at 56K miles.
    The issue has been going on for the last 3 oil changes (9 months).

    Mobil 1 isn't my oil of choice people have spun bearings using M1.

    Whether M1 caused bearing issues is debatable (especially since there are no reliable data...) however there is a leak, and M1 or not the leak must be addressed.

    However, if you see smoke and smell oil, there is a leak. We can't help remotely with that, regrettably. You'll have to find the leak or pay someone to do so I'm sorry to say.

    (The oil consumption itself is not considered an issue by Subaru; see manual for max consumption expected (1L/1K is "normal"). If you don't like it you can experiment with other oil brands and formulations and viscosities. However since you see smoke and smell oil you do have an issue).

    If you're smoking, then there is def a leak like SD_GR said. You are probably leaking out from the return line and its hitting your exhaust system. That seems to be a common issue due to fatigue of the line...I know first hand. Not sure how old your car is but I would check there first.

    I've tried locating the leak myself --- the smoke was only there one time and I was not able to be make a confident diagnosis.
    I am aiming to go this week to get it looked at and I'll update.
