UslessPickles always to the rescue, thats exactly what i was confused about.
BKeef we drive on the same side, what confused me was when you wrote " its mounted on passenger side behind computer board" so just a miss understanding.
So BKeef's setup is different from what i was after although i have to say an environmentally consious one, which im also going to immitate, but my initial concern was the setup UslessPickles mentioned which will stop oily vapoures from making their way back to the intake.
So anyone got the other setup done?
