okay, i was thinking the hose that originally went to the intake manifold was needed to pull a vacuum... now its not:dontknow:
AWDisuzu said:sorry, please forgive my drawing skills. for the supercharged guys, the blue hose needs to be on on the low pressure side of your intake so that it sees suction. basically, it needs to be right behind the air filter.

blackviper said:I'm still kind of confused. With Justin's catch can you have a filter on the top. Do you need to tap the catch can and run another line to the air cleaner? I run a different CAI setup. What about the one way valve previously mentioned? Thanks again.
Prof said:Mike I differ with you when you say "complete circuit". The purpose of my oil catch can is to lessen the oil spray that comes from my oil breathers. That spray contains oil and condensation...I have no need to re-inject it into the intake. I want to get rid of it via the catch can and not burn it off by putting it into the fuel air mixture. As you say too much can cause pinging by lowering the octane (I think it would take a significant amount to do that). I want to purge the blow-by created by the pressure that is already within the pressurized (drivers) side of the engine, rather than have it spray all over the place. I see absolutly no need to re-burn that water/oil mist...my engine in a normal configuration may do it for EPA considerations, but from my standpoint it is just a mess because we use breathers to expel it in forced induction systems.
You will have to re-state your reasons for the full-circuit if I have mis-construed your meaning...but why not just catch the blow-by and throw it away? That's what catch cans have done for 40 years...eliminate messy oil blow-by.
Maybe we are talking about different objectives?
what about water?You really shouldn't be finding anything in the catch can if you're running synthetic oil and if you don't have any mechanical failures

and some flush for your eye!Prof said:Boomer's comments are what I am hearing from two or three engine builders...they all except Mike seem to believe that the pressure from the left bank of the viper engine is normal and to be expected. Sean Roe suggested that a good demonstration of the pressure in the left side of the engine and the turbulence present can be viewed by looking into the oil filler port with the engine running...have a big towel in hand when you try this.....
