You understand that cranking the engine will just cycle the debris through the crank case and eventually out the AVCS lines, right?
Pull the oil pan, pull the valve covers, and pull the oil pump. Clean the pump and pack it with vaseline before reinstalling, clean everything with lots and lots of brake clean, and put it all back together.
Reinstall the turbo, prime the oiling system, start the car and let it run until the fans come on. Shut it down, and change the oil/filter.
