Crankcase vapor vent/recirc system

***TitaniumTT*** · 10-23-2010, 03:12 PM

Most of us seem to just "T" the oil filler nipple and the center iron nipple together and run it off to a puke can. Some leave Jem open, some cap them but what would be the best way to clean out the vapors, keep the oil moisture free and not add any check valves, pwm or ecu activated valves? Something very very simple.

What I'm thinking of doing would involve a 2 chamber "tank." Both vertical. The first chamber would have a filter on the top, a drain on the bottom and would be connected to the center iron nipple.
The 2nd tank would have no filter on the top, be plumbed to the oil filler neck from the bottom, packed with SS wool, and the top would be plumbed to one of the TID's.

The thought is the small amount of vac created would constantly circulate air through the crankcase. And oil that traveled up the center iron would first be pulled back in before getting to the puke tank where it could be drained. Any vapors or moisture that made their way up the filler neck (very unlikely that oil would as I have basically a funnel in there to keep that from happening) would be caught by the SS wool before getting pulled into the intake.

Thoughts, comments, suggestions are all welcome especially from Ted. I know he has a great deal of knowledge with this.
