    brother had one in his car (B18cR) and had it in there for a few months. he drives his car hard a fair bit.

    the can was empty when he took it out.

      My understanding is that a catch can simply 'catches' oil that has got to the top of the engine rather than recirculating it into the engine and burning it.

      Pretty unnecessary on a street driven car.

        Are you sure you brother hooked it up correctly?


        I had a B18c in a EG as well.

        I used to hook it to the intake pipe and rocker cover and it didnt catch any oil on my first time at track.

        Then a friend showed me i had to hooked it up to the PCV Valve, and my next time at track it caught about 1/4 of oil in my cusco catch can

        Was using motul turbolight engine oil as well.


        AS for daily driving, i didnt notice any oil being caught at all, and i did odd occasion fanging within the legal speed limit

            Here is a pic of my above mentioned oil catch can set up.



            As already said, this setup was in the car for quite a while...(ie, before i even bought the car)...There was no oil through the line and no oil in the catch can either. However, the fact there was a breather attachment might have something to do with that???

            I have since taken the catch can out, and attached the breather to the rocker cover...I would prefer to have the oem setup however...this is a temp. fix.

              A lot of people get this wrong, moreso wrong than right.

              The 'normal' direction of air flow is from the Intake arm, to the Rocker cover through the motor, out the block, through the PCV valve, then to intake manifold, where it is burn it to the motor.

              Because the PCV valve is a 1 way valve theres no point putting a catch can were the breather is on the rocker cover, because air is going 'in' to the motor there.

              You need to put your catch can, between the block and the intake manifold. I have my catch can in between the PCV valve and the intake manifold. So it draws oil vapours through the catch can before its sucked into the motor.

              You don't 'need' to install a oil catch can, but if you track your car then its probably a good idea.

                ok well given that description...the setup on my car was completely wrong anyway...so i guess there was no harm in getting rid of it...

                Also explains why nothing was happening in there...lol

                Installing it correctly would see results. (ie. oil)

                Does anyone happen to have a picture of where the PCV line returns into the intake manifold...cheers.

                  the ITR already has (like most modern cars) a catch can that traps oil before circulatign crankcase vapours into teh intake manifold...

                  you need to decide if this is *adequate* for your purposes...

                    I'd think the condition of the motor would also play part in the amount of blow-by you get.
