I thought i would would share a few pics of my custom oil catch can. It is 2.5L.

My mate knocked it up for me fairly quickly so it has not been polished yet.

Excuse the engine (it needs a degrease) as it has been in the garage for about 12 months not really going anywhere.

Happy for comments.

just letting you guys know but having the breather on it make it illegal. nice job by the way

this is true but I never said it was legal!

This car is orientated to track duties and very rarely sees street use, usually only going from home to tuner and back so not a real drama for me.

is there a line from the front of the turbo to the catch can or am i seeing it right (pic 3) your still going from the turbo to the top of the rocker cover. i may be wrong but all i can see is two lines from the rocker cover to the catch can. The line going to rocker cover from the turbo needs to be plumbed into the catch can as well to get a vacuum in the catch can to pull the gasses from the rocker covers.

yeah... i dont think its really doing much, in fact its doing nothing for your right rocker cover, and the vacuum from the turbo is probably sucking the fumes from the left cover through the catch can anyway. is there a reason you didnt block off the hose from your rocker cover to the turbs?

it looks the goods anyway (Y)

looks the good mate, got a few questions tho

is ur mate interested in making more of a different design, spex would be supplied

is it baffled

r u running a drain back to sump

is there any reason its on the passenger side, most cars run in on drivers side (something to do with the crank pressure helping it drain back)

cheers

The way the OP has it set up would be a huge vaccum leak and also would be sucking oily fumes straight from the top of the head into the intake, rendering the catchcan useless.

You can run your catch can atmo. if you block the return in the intake pipe and also block the PCV from the plenum to head. Then you just run your two breathers to the catch can and vent to atmo.

If you want to plumb your catchcan inline, then T the two breathers into one and run it to one port on the can, run the other port to the intake. It's best to fill the can with steel wool as in this situation it's acting as an oil/air seperator (even better to have a baffle in there too so the fumes have to go through the steel wool before exiting).

The atmo. setup above, is acting as a "catch" can and is more for high hp track cars that might be prone to breathing, you also don't want oil fumes in your intake when you run a lot of boost and timing.

Just been to the mechanic to ask his opinion.

He said that it is working fine and is doing it's job as a catch can. He also said that if i block off the PVC pipe then i will have idle and running issues etc.

Rowdy - the reason is that the mechanic advised this was the way to set it up. It is there to catch oil if i have a big issue and to allow the engine to breath when at the track.

ahh 33 s2 - my mate will be happy to buiild to your specs. if you are interested you can PM me your details and i will pass onto him.

I am not a mechanic so have to trust what the workshop says as they do a fair bit of work for drift, track and road cars predominatley Jap imports.

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
    • @GTSBoy yeah sorry i know thery are known for colors bud those DBA are too in colors 🙂 Green will be good enough for me
