Snaken
I did what you are considering last year. I was alway getting at least 1/2 litre of
oil in catch can after 15 minutes or so on the track (road use none)
I ran a AN6 line from bottom of c/can and welded a tee into the base of the dip
stick tube with one way valve. It works great without ever needing to drain c/can again. Check mine out next Sat. if you like as very easy to do.
