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?

    • @dbm7 and @GTSBoy thank you both very much! will give that a shot!
    • Sounds good. Provided the panel is flat/level I'd be happy to start the painting process.  While you are learning, for sure you could do this. Its only paint, you can always sand it all back and start again. Its only your time and money on materials, but while you're learning, really its time and money spent on your education.  Once you know how to do this bodywork and painting, you won't want to waste your time and money on frivolous activities lol. 
    • Yep I will use a guide coat after putting filler, I will do it on the whole panel as I'm a beginner so chances I've made quite a few errors. In that photo, I think that was a low spot, I just for example said to pretend it's flat but I will put filler + guide coat after to assess where I'm at. Yep with that picture, the panel is wet as it rained when I took the photo. But all those scratches are completely smooth, I went over it with 240 grit and can't feel it, even with my nail digging into it. I was legit thinking to buy a 2k can and spray primer to see how it turns out but then thought to myself it's going to be a mess doing it haha. Good mention there. Thanks for all that info I think I know what to do next.
    • Prior to laying down the primer, you need to make sure the surface is completely level. For example, based on this picture, I strongly suspect that the areas marked in blue are higher then the area marked in green.  If you spray primer over this entire area, then paint and clear it, the finished result will 100% show the low area. It will stick out like dogs balls. Unfortunately the paint won't magically level out the low areas as you lay it down.  Without seeing it in person, I expect that the green area will need to be filled, then use a guide coat and check that the entire repair area is level with a large sanding block.  With this picture, are you saying that even though you can see the scratches, the panel is in fact completely smooth and flat? If this is the case sure you could prep and paint it as it is.     The picture with the paint you described as blistering, it's hard for me to comment on from the photo alone. It looks like the panel is wet? Dunno, looks strange. Does the panel feel as smooth as glass when you run your hand over it? **** Going back to your question again, generally you would only sand the primer if you made a mistake while laying down the primer.  If the panel is prepped properly and you lay the primer down properly, you should not need to sand the primer.  This wouldn't work - Don't prep the panel. Spray primer and see how it turns out. Sand the areas where the issues appear. Spray more primer and see how it turns out. Sand the areas....... Yeah you'd go round and round in circles getting no where.
