Thanks for all the replies and pix.
It is something I will put on my to do list.

I used a water separator from home depot, 90 degree brass fittings, and fabbed an aluminum bracket. Installed on master cylinder. It is quite small and fits nicely

The oil has fuel in it, I believe one of the purposes of the PCV system is to evacuate any fuel blowby and keep it out of the oil. I suspect they can not catch it and be EPA compliant, so the fuely oil is burned through the engine.

If you like, you can send it to my e-mail (left click on my ID and view e-mail address) and I can post it up for you.

Yeah, give me a bit and I will snap a picture of it. I used same setup for about three years on my toyota. I drove the car for 50 miles and it has an 1/8 of oil in the bottom of it. I needed to remove and cap the drain valve on the bottom of the bowl though. I just cleaned out the plenum and didn't want the oil in there again.
