Question about 2001 Subaru Impreza
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 .

Can you or someone observe the color of the smoke as you increase the RPM?===Before you next oil change. Do an engine flush.This will clean out the piston rings and internal of the head.===
You can CAREFULLY listen to the turbo bearing with a stick. Place a stick and CARFULLY listen for the turbo operate.
If it's the org. engine it will has over 90,000 miles on it.
It's normal to has the valve stem seal/oil seal on the head to leak oil into the cyclinder.
The longer the car sit the more oil accumulated.
The smoke you see is the motor oil drop from the seals.
It land on the top of the cyclinders and it create black smoke at start up.
The inexpensive fix is to start using high mileage oil with seal conditioner.
This will help soften the rubber seals and help reduce internal oil leak.
The correct fix is to wait until it's time for a head gasket replacement and let the professional service the head.
Complete head service is the only method to stop this internal oil drip problem.
