I agree with Hammer. The old blow-by tubes defintley have moisture as well as oil mist in them. Don't see why anyone would want to run any amount of moisture throught the turbo. On my 01. 5 I eliminated the bottle and ran a 3/4 inch hose down about 2 inches past the tie rod. No problems no drips very easy to do. However some of the other solutions sound valid but just not through the turbo we spend mucho $$$$$$ on gauges and other things to protect them.
