Y dose my subaru impreza 2ltr turbo smoke wen it gets floored it only smokes wen i come to a stop

head gasket is blown

White smoke is usually coolant, oil is usually a blue color, most turbos r cooled by coolant so U may have a coolant leak in the turbo, may B a seal or crack in the turbo. Check your coolant level occasionally to C if it drops.

check your turbo
turbos tent to leak from the seals also its always good to buy an oil catch can

clean the engine with degreaser (cover electrical stuff..alt any obvious plugs etc,)hose it clean,let it dry and run it,take to someone who knows what to look for,..even smart buddy,smoke could be several things,even worn engine

you may be able to from the converter back, maybe???? if the turbo pipe is the same diameter and the flange size. Of course, a muffler shop could make any modifications to make it fit. one thing you want to keep is that it all bolts together where it does now, So you can unbolt it for service.........Dont let them weld everything together.

probably leaking rocker cover gasket ,oil slowly lands on exhaust,ive got one and had exactly the same symptoms and rocker cover gaskets were the issue

It will end up in the intake and you should be getting white smoke from the exhuast

Hi , I`m not sure about the 01 model but the 98 model got this roker cover gasket problem because it`s too close to the exhaust and with time can`t handle the heat.So when you rev the car , dropping oil on to the exhaust and one little drop of oil can make big smoke which coming up around the turbo. Hope this helps .

well dual fans obviously maybe one is no longer working test it and see

most likely the turbo, if its a darker or bluish smoke.
