I've just completed a PCV clean and replace on my 1994 850 Turbo. Before making this repair there was no cam tick but once I got everything back on and started the car there was a very noticeable cam tick. When I remove the oil cap a little smoke comes out and the oil is really sloshing around in there. I wouldn't think that I would do any damage removing the intake manifold. Any idea what may have caused this to happen and how I can address the issue?
