The only way for crank pressure to get out is through the PCV system and that has the catch can on it. the driver side has the turbo oil return on it so that one is blocked and the passanger side is the catchcan. The catch can is between the valve cover and the turbo so it only pulls pressure from the crankcase not push air into it. So somehow its pulling alot of water vapor from the crankcase that shouldnt be there. Right? The only place water can come from and get inrto the crankcase is the cylinders. So thats either very wet air/ 100% humidity in the air charge of head gasket. Im just thinking outloud here trying t work through this. I guess we'll find out more when we drain the oil next Tuesday and see what it looks like.

And Im not running E85 yet on this engine.
