Well his set up isnt an "oil breather" the breather system has a breather on it and doesn't send those sh*t gas's back into the intake...

You could hook it up as shown with a catch can that has a breather on it and not run a line back into the intake.

Don't have pics of my old set up on this computer, but both lines off the head simply run to a catch can with a breather and the bits get blocked off so the oils in the catch can and gas's out the breather!

Yea mines like that aswell... one hose from the head to the catch tank and nothing comin out the other side except a little filter on it, dunno if thats how its meant to be the workshop i go to did it.. i didn't need to block off the intake pipe cos they made me a 3" S/S one...

Blocking off is obviously only if you have the bit there on a standard intake pipe :laugh:

Usually its better to run 2 lines to a catch can with a filter ontop of the catch can so both lines are free'd up rather than using one, i used one small one and it built up pressure in the system which meant bye bye turbo oil seal! Made 2 fat lines with a breather on the catch can and it didn't pressurize the system and kept all the sh*t outta the intake of the car, you'd be suprised when you empty the can how bad that oil actually is lol

I guess the blow-by on a old rb20 runnin 20psi was always goin to be greater than most though :laugh:

My catch tank is as clean as when i baught it... i'm running 6psi mind you lol

so exactly whats the correct way? wether its legal or not i just wana know cos some people do it differently i suppose or the way your saying jazza80 is that the right waY?

If its clean inside, its means you have f**k all blow-by which means your engine is in top nick, and im not suprised running that boost level, sounds very safe :laugh:

Legally, it isn't supposed to vent to the atmosphere, so running the lines to a catch can to catch any bad oils, then back into the intake (for the gas's) is the best way to do it.

Illegally, to keep all the sh*t out of your motor you use a breather and don't run it back into the intake...

Just make sure the system has a way to breather (wether that be via the intake or a breather) as without it it will pressurize and cause you some big big problems.

I have found that from having catch can problems in the past with my last car, lines to catch can were abit too small.. built some pressure up and blew the oil seal on the turbo, made both lines bigger with the breather ontop of the catch can and it never pressurized the system! Thought id try to help out so you didn't end up doing that lol

    • HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.
    • The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
    • Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?
    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
