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?

    • Don't do it if your gearbox box has already having syncro issues. The short hifter will put a greater load on them. If you must I remember Nismo did a shorter shifter, with the top part being physically shorter and the part that went into the gearbox was the same as stock. In saying that I've had a C's short shifter (I think) in mine for many years, which was given to me as the previous owner was not sympathetic to the gearbox. Thus forwarned I was careful and had to modify my normal changing style. You have to be super accurate with your clutch and shifts
    • Well, after a week of daily driving and having to crawl out between the wheel and the side intrusion bars. I got myself a quick release setup. I went with an NRG short hub and Quick Release with some cute heart cutouts on the pull tabs. Nice and matchy matchy with the rest of the interior accents I have going on.  The only downside is the total stack height even with the short adapter is longer than the old HKB boss kit. Luckily I had some adjustment left on the column so move the wheel away.
    • stock shifter with new bushes, springs and cup will improve it. Gktech do all the bits. The opinion as the years have gone on is the redline is not great in old gearboxes.
    • Hi all   what short shifter do you use on your skykine r34?   my synchronous does have a problem and i was getting huge delay and grinding sound between 2nd and 3rd, did put shockproof red heavy stuff and it is great now/ no issues   would in your view short shifter screw this up?   people seems to suggest/ use cube short shifter and there is standard and premium. Seen review of premium as much better and less play. Thoughts?
    • Yeah, there's a bit of a density and friability difference between pebbles and any of those other things. Silicone will definitely float in oil and so will be mobile enough to move around. Although, again, if it is upstream of the filter it really shouldn't go any further. I would only ever worry about silicone when it is in places downstream of the filter. Upstream of the pickup is a whole 'nother matter. We've all seen what that does. I have seen the most abominable crap settled out in industrial gearboxes, trunnion lube systems and the like, without any sign that any of it has touched anything in the machine. Just chilling in the bottom, waiting for the inevitable operator error that causes the whole machine to need to be dismantled for repairs.
