Overfill of oil.went into air filter and turbo hose, this has been cleaned but I have really bad dark smoke coming out of exhaust pipe

It start white and blue then turns dark smelling of Burnt oil

Informed it would go 3 weeks ago and to drive on the motor way to burn the excess oil, this is not working, the smoke has not decreased

I've had the engine and everything looked at but been told just to drive

Any suggestions

Someone said a whole new exhaust pipe might be the answer

Drain the oil from the sump plug and refill again - cheaper than getting issues in turbos!
