I "presume" that the preferred/ best method is the one that keeps "stuff" out of the crankcase and allows the engine to run smoothly at all rpm's.
Thanks for all your input.  |
I'm not sure one way is more effective than the other at pulling vapor from the crankcase. Spud has run his 14,000 miles in the 'unofficial' orientation without ill effects. Myself and others have thousands of miles in the unofficial orientation.
To me, it's a question of whether you want more or less fluid in the catchtube:
- Official (cap toward top): More fuel vapor condenses in the catchtube. Less fuel vapor pulled into the air intake. Higher risk of filling up the OCS (and blocking suction) on long trips. Potentially better tailpipe emissions, but more fuel to pour on the ground.
- Unofficial (cap toward bottom): Less fuel vapor condenses in the catchtube. More fuel vapor pulled into the air intake. Lower risk of filling up the OCS (and blocking suction) on long trips. Potentially worse tailpipe emissions, but less fuel to pour on the ground.
For my part, unless CSC says the OCS orientation will affect my warranty ... or until I learn compelling reasons why burning fuel vapor from the OCS is worse on the environment than pouring fuel condensate on the ground ... I intend to mount my OCS 'upside-down', so as to burn as much of the fuel vapor from the crankcase as possible and to collect as little fuel in the catchtube as possible.
