I posted something a while back in another thread about a Schmiedmann gadget...

There's a sight glass to monitor the level in the tank and a drain cap in the side.

... and it looks like they are now in stock, and even on sale. With shipping to the US the cost is $76. I might order one, just to have a semi-ready to go kit. The only thing that keeps me from doing it is wondering whether the catch can will actually remove moisture from the CCV system or just collect oil from it. After all, the problem is with condensed moisture in the crankcase.

The 400 series.

Edit: I only suggest this if your crankcase pressure is higher than normal due to modification. Otherwise, the OE design works fine when maintained properly.
From your sig pic I'm guessing you have a turbo on your engine; is that the reason your crankcase pressure is higher than normal? Do you have any info on how that ProVent is plumbed in?
