As stated, pull the inlet off to the turbo, and verify that the thing came apart. White or whit/blue smoke can come from many things on these, but from your issues, sounds turbo related. If the impeller is chewed to ****, then check the cac for debris. If its not chewed to ****, then it may have just **** the seal. Check the down pipe for oil. If there is metal in the cac tubes, changing it wouldnt be a bad idea. Get one thats not a factory one, as the factory ones have a tendency to blow off end tanks. I'm running a car, that was around 450 bucks, and is holding up.
As fir pulling your valve covers and oil filter, the metal that comes from the turbo isnt going to go to the crankcase. If it passes thru the cac, it will be in the intake manifold and cylinders, but that is a big "if" it makes it padt the cac.
For a replacement turbo, contact KC Turbos. Great turbos, and his customer service is amazing.
