G'day everyone,
I've been up ALL night long mind f**king myself as to HOW TO INSTALL an OIL CATCH CAN.
I understand that it's a relatively simple job, just time consuming at best. HOWEVER, I am absolutely and entirely LOST as to what happens with the Air intake part of things (does the catch can need its own air filter) and even as to whether I'm going to HAVE TO modify somewhere along my air intake to allow a clean flowing air or "vacuum" as many people have mentioned. WHICH THEN leads to me wondering will my Air intake sensor be stuffed up if I cut holes or put filters in my Air box.
As you can see, I am totally MUDDLED and have spent the last 4 hours searching and searching for a STEP BY STEP process for installing a Catch can in a N/A RB30 Sedan...
If anyone could make simple

  • step
  • by
  • step

Instructions, from begging to start and explain to me as to whether I even NEED to put an air filter/air vacuum for a catch can to work?
Pictures and VERY simple instructions/terms if at all possible would mean the absolute WORLD.

Thanks a million!

Just take off existing breather pipe that goes from rocker to plenum, and add catch can inbetween. simples.

Or better yet, dont worry about it and sell it.

So everything I'm reading in relation to the air intake / pvc sensor etc, is to mainly do with Turbo'd vehicles, and doesn't apply to me?

Just as simple and straight forward as in this video which I've just stumbled on?:

^^^

He talks about air intake as well and that "You'll know what to do when you get to that part", WHAT if anything do I need to do in regards to the intake/''that part'' of the installation etc?

Or is it purely as he states; just so he can access what he's doing more easily?

Dude, it is so easy.... One end of can attaced to rocker cover , other to plenum. this photo shows the hose that is replaced, the catch can hoses go here. when you take that hose off, attach the catch can hoses to the two spots. that is where the blowby that might have oil mist in it gets sucked into the engine, so that is where the catch can has to go to catch it! If you are still confused, I can't help you !post-107339-0-39394500-1368360071_thumb.jpg

Cheers a million guys, you've made it really as simple as it should've been from the word "go".
Obviously it was due to Turbo'd vehicles/installs I was reading and getting confused, as there seems to be just a little more work involved when installing a catch can on a Turbo apposed to a N/A / Standard RB30.
Just to completely clarify, I've circled what I have to remove and place the catch can 'in line' between these two fittings and instead use the catch cans braided hoses.


The circled hoses are the ones I'll be removing when installing the catch can, Yes?

IF this is NOT correct, can someone PLEASE circle and upload on the same image what I have to remove?

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
