I saw this exact same thing on my car. I pulled the turbo at my dads house, needing to get home I put the turbo back on and went home. I then ordered the head gasket, but before I could get around to changing I developed a rod knock.... I assume the head gasket completely gave way and it dumped all its oil, thus the rod knock.

I'd leave that car where it is and change the head gasket.... I sure wish it had
