the reason why theres only one hose on your setup is because where its plumbed into the rocker cover actually SUCKS air in, in which case it's just sucking unfiltered air from the other inlet on the catch that isn't hosed.... a breather filter usually goes there.
you have to connect BETWEEN the PCV valve and plenum... theres a thin black hose in the middle of your plenum that goes to a black L shaped valve under the injectors near the inlet runners...

Beeza has it right
my mechanic said that the other ones acts like a breather. But i dont think it does.
the one you've got it plumbed into is the breather.Quote:

Rule of thumb:
- You take things you need to fix to your average mechanic
- anything performance related, take it to a workshop that is actually acquainted with performance side of things :thumbsup:
I will just tell him this afternoon to connect it like beeza's one, thats the correct way isnt it
Beeza's way is correct, print out the picture and show him as he probably doesn't understand the function of a catch can.Quote:

The effect is that it can potentially lower fuel octane rating in the combustion process but at the same time it allows blown-by oil to recirculate in the system and get combusted and go through the catalyst to be cleanly burned (somewhat) instead of it being a pollutant. On turbo cars it will lower performance drastically through octane loss as well as the insides of intercooler fins being coated with gummy oil.
Every car does it but severe blow by is usually caused by worn piston rings. During the combustion stroke (3rd stroke in the 4 stroke cycle), combustion pressures leak past the rings and back into the crank case which in turn burns and vapourizes the oil which in turn goes through the pcv valve and back into the intake manifold hence why it has to be plumbed there.... you should see how well these work on even a new v8 lol.
on another note i hope you have a "REAL" catch can instead of one of those cheap fake ones. The catch can and plumbing needs to be air tight otherwise you'll start getting sever idle issues.
This is how you tell if your catch can is functional or rice.... the reasons the ricer models still get sold and installed with no idle problems is because their plumbed in the way you have yours
thast some good info, i printed out the sheets already lol aim going to show him how to put it on, also i got a cusco catch can so it aint no cheap brand
may still have an air leak, i had a cusco before too... had to take off all the bits that could unscrew and use sealant anyway...Quote:

take it off and block one inlet with your finger and blow through the other.
oh and no point getting your mechanic to do all this, just do it yourself.
goto supercheap/autobarn and order some fuel line grade hose.... DO NOT use some sort of soft rubber or vacuum hose.... when oil starts going through it gets absorbed and then expands then goes really soft... when your car is on idle (vacuum) the hose squishes together coz its gone soft
yeh looks like iam goign to have to get extra hose's and hook it up properly and i will check for air leaks i doubt it has any but will check
