Depends, is the interior of your can hollow or filled with filtering material (stainless mesh etc). If its hollow, hooking it up like you said would be as good as not having one.... oil vapours in -> oil vapours out.

Could i - In theory, Block the hose that goes to the intake altogether?

Yep, I've done so with a suitably sized brass bolt from pirtek. Only thing left to do is hang a filter off the free cam cover pipe or connect it to a vented container. The cam covers can't be blocked off altogether, it needs to be able to release any pressure build up.

The engine doesn't need any oil in the intake, we're not driving rotaries here. :( Macka, adam32 (i think), deesh and myself have diy jobbies. Ask us at the next cruise.

but remember theres 2 types of catchcans, some just catch the oil and then u have to empty it,these are basically empty containers which are easy to make, these have to have some sort of breather, the little filters are really good for this as when u just have holes in the top it can sometimes splash out, then theres the catchcans that filter the oil inside it,which kinda have sections in it, inasnt if i was u id drill a hole in the top get a fitting maybe 1/4" and screw it in,then put the filter on top of that,would only cost ya 3 bucks for the fitting and 10bucks for the little filter, there actually little pod filters there cool

Turbomad - my intlet track is the same - zero oil in it, so it'd be pointless for me to install one too.

Yet 2 friends with turbo cars both hae oily inlet tracks....

Strange... Does the oil come from the turbo leaking oil around the bearings or does it come from the crank case brething up into the cam covers and then out that way??

Well I guess it can come from both, seeing as our Skylines are still farely new low km cars it's unlikely that boost will slip past the rings pressurising the sump and forcing oil out the rocker, this is mainly a problem with cars running very high boost.

i made mine myself and mine is exactly the same as yours except it has a filter/breather on top and a drain plug at the bottom to empty it when the level gets too high.

this type of design is so much simpler than a plumb back design to the sump or filtered air back to the intake and so much easier to make and install.

and the benefits are exactly the same: no oil in the intake, reducing the chance for detonation.

so u r running both the cam cover ventilations to the catch can?

there r about 3 ways to set it up, not sure which one i am gonna do.

Have u found much oil in the catch can they way u have yours setup?

Venting to atmo is the easiest way to set up yes, but it's not legal, I got a canary on my vl turbo for that setup.

INASNT the hose was fairly cheap can't remember how much, it's funny I pulled the BOV off the other day and there was some oil around there but not in the catch can, maybe it was always there from before I fitted the can, don't know.

well i got canaried on friday night! :D

he asked what the catch can was even tho i didnt have it connected and said i couldnt have it there, even tho he didnt now wtf it was.

That's a beauty canary's for an empty container not connected to anything haha! How did you go with the roadworthy? Did they pick on your pod too?

he didnt actually write down the catch can on the canary form!

I went today to get it checked by roadworthy place and guess what, i dont have to change any of the crap the cop wrote down! :lol:

COPS DONT KNOW SHIT WAS THE GENERAL THOUGHTS OF THE GUYS THAT WORKED THERE!!

INASNT - wouldn't it be tempting to take the paperwork to that cop and show him that you didn't need to change anything to pass, just to prove to him he has no idea :lol:

But then I suppose he would pick on you evertime he see's you :D

i was thinking more along the lines of taking my roadworthy certificate and pasting it to his forehead with a 12 gauge shot gun!

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
