    Blown Turbo Seals?

    Stock 02 wrx

    Yesterday i finished replacing the drivers side head gasket due to what i thought was an internal head gasket leak.
    Internal Head Gasket Leak

    I have the same exact problem after HG replacement. Coolant burning out of exhaust, P1507 Code. Irregular idle, Struggles to run at low rpm, above 2 or 3k is strong.

    I'm looking for input as to how to go about checking the turbo for internal coolant leaks.

    Thanks all

    car is fixed.
    YES!

    i replaced a cracked hose from the turbo wastgate to the boost control solenoid and cleaned the IACV, and stopped getting the cel.

    Awesome, congrats. Did the smoke go away too?

    Thanks,
    Yep, the smoke is gone. Where it was coming from, i'm not sure.

    i had smoke from:
    -the turbo area of the engine compartment (months ago, briefly), \
    -vapor from the exhaust (the whole time), and from what looked like
    -the thermostat (which later turned out to be the heat shield of the center exhaust pipe).

    Perhaps the vapor resulted from the broken hose from the turbo wastegate to the boost control solenoid causing some kind of... i don't know..

    or, the coolant vapor was from a possible previous coolant leak that left residue in the exaust system and i didn't give it long enough to evaporate before freaking out...
    BUT Cleaning the IACV stopped the cel.

    It runs amazingly, especially since this is the first time I've driven it with a NEW clutch.. i forgot how much i love these cars.

    I really can't wait to start beefing power up now that i have a better understanding as to what's going on under the hood.
