catch can install and hosing

[hapisok]

i've been running with the Injen CAI for a while now and just recently added the RX catch can. where the return line that connects to the Injen, just behind the MAF sensor, i've been finding more oil lately. my question, is that line supposed to be connected to the catch can as well and would adding a T connector to both the clean and dirty sides of the catch can keep everything operable. or at that point, would i just plug the port on the Injen? not sure how the vacuum would have an affect on either clean air side as they would be connected. the catch can is catching oil but oil is still being ingested via the driver side. hope the included photo makes sense.

Need to get the oil breather cap for the driver side. That line is the fresh air line. You will find some oil on the driver's side until you get the oil breath cap. When you install it, must remove the fresh air line and cap off the two ends it was connected to. Check out: http://www.camaro5.com/forums/showthread.php?t=183207

awesome, thanks for clearing that up

[hapisok]

is there any reason why its not T'd off to the dirty side of the catch can which would eliminate the need for a breather cap?

here's what i did, capped off the nipple on the Injen and T'd the driver side to the dirty line. gonna check my fuel trims and see how it does. it made a difference when i first turned it over as it started loping like it was gonna choke itself out. i'll monitor it and post some an update.

tracy, if you could chime in i'd appreciate it.

thanks.

I'm not sure you should do that, but hopefully tracy chimes in to clear things up.

Yes. The clean and dirty sides always need to be separate as the filtered clean fresh air is used to "flush" the damaging combustion byproducts out of the crankcase. Thus either complete the connection from the OEM fresh air line to the injen, or add the checkvalved flow controlling breather kit.

I did a double catch can set up. I saw how much oil was getting into the TB when I disassemble the EOM system. One is on the dirty side and the other is on the clean side.
Tracy sells a double can setup and he did mention that a double can is better than a single one.

Next srping I'll go with RX Catch Can since mine are doing only 75% of the job now, but I witth definitively have a double set-up.

Last pic shows how much oil left into the EOM Air tue even when I finished cleaning it. That oil is coming from the Clean Side and goes directly in the tube just in front on the TB...

Good job Montreal!

Thanks. You where right my cans are not doing the best job now...So I'll be buying yours next spring but still will keep the double cans. Actually there is more oil coming frm the Clean side that the Dirty side now, and that oil goes directy into the TB while the other is going into the engine itself...
I had to take the breather off since it did'nt clear my new ACS-Nickey Stinger hood.
But I'm really proud of the bracket that olds both cans together. It's my creation.

now im all confused...sad thing is i did it to myself. i thought the line on the back passenger side as well as the back driver side were both "dirty". the line that went from the rear driver side to the Injen had all kinds of oil in and around the hose where it connects to the nipple behind the MAF sensor. guess what doesn't make sense to me is that the passenger side hooks up to the IM and the driver side to my intake...so shouldn't the vacuum on both those lines be the same? and if so, why can't they be connected to the same catch can?

thanks for the responses...

i feel like an idiot...i understand how its supposed to work now. just doesn't make sense that the fresh air line IN is coated in oil. if its drawing air in...how are those gasses escaping? guess the only way to really eliminate it is like you said...with 2 catch cans.

thanks

The fresh air line is the 2nd point of ingestion into the intake air charge and at WOT there is little to no vacuum from the intake manifold so through reversion oil vapors are pushed into the intake air bridge thus the oil you see. The breather kit eliminates this and then of course you remove the OEM line and cap it so excess unmetered air is not entering the system.

ahhh...why couldn't you use the big word earlier...REVERSION! thanks tracy . i was playing with it last night trying to figure it out and that makes sense now. of all the researching i did, not once was there a mention or explination of anything like reversion due to the lack of vacuum. i ended up replacing the OEM fresh air line until i get a breather.

thanks again
