Took the r33 out today was fairly hot (bout 40*c) have been running "redline lightweight". And found that it pumped a considerable amount of oil out the breather (bout 250ish ml). Has anyone had this issue. Wasn't an enthusiastic drive either, 45mins or so through Adelaide hills.

Aerates too easily, they changed the make up of the oil, used to be good stuff. It seems to be crap now and 'bleeds' everywhere...

As above choose something else, or run a catch can lol.

Changing the oil sounds like the go then. I was only running that oil due to the syncros in 2nd getting a bit notchy. I guess I've just donated $120 to bursons. Oh well, I spose I could have spent it on worse things.

Umm i think you will find that your engine oil is diff to your gear box oil,

that is what i know bout it. :yes: Ok just re read,get rid of redline,had same prob as you,bleads out of breather.

As others said change to something else.I thought at the time years ago that this stuff was a great fix,

it was'nt.

It's not the first time it's had redline oil, I only changed it because it had been a while since it was done. And second had started to get a bit harder to select than normal (hence reason for the change). We run it in the track car also and it's been fine. I'll take it for another bit of drive tomorrow and see if its the same. I just wanted to see if there was some sort of gearbox issue that causes the box to pressurise.

Just filled my box up with lightweight shockproof and even at the track, I have no problems with it spitting out of the breathers. I know gtr Joey had this this issue also.it spewed out a few times but the last few months, nothing. Slight overfill maybe?

When I bought my oil off the distributor, I mentioned this issue to him. He said he hadn't heard of any formula changes at all. Maybe a bad batch?

I've had the sht in my box for years. I used to have issues with changing into 4th when at 7-8k I'm 3rd.

I wouldn't run anything eles in a gtr box, it's awesome stuff, I'd b devod if they changed the blends and f**ked it.

      Yes...but look at the numbers. There is a tiny tiny fraction of the number of Joules available, compared to what is used/needed. Just because things are "possible" doesn't make them meaningful.

      Somehow Vertimass/Oak Ridge National Labs has figured out a catalyst that can convert ethanol into C9-C10 hydrocarbons in basically a single step without ending up with a bunch of ethylene or similar waste products: https://patents.google.com/patent/WO2023224867A1/en I still don't think anything like this will keep us from needing to transition to EVs regardless along with all kinds of other electrification, but things like this will go a long way towards alleviating the problem of how to electrify things like planes. Renewable diesel is seemingly an easier problem as well, Chevron is already running refineries for the stuff and the primary feedstock is tallow and other waste fats from agriculture.

      Ok so I have sorted everything with my uniclutch and  i can offer up a bit of feedback and some things that might help others.    I found problems with factory damper line. Weird shit and had trouble with peddle adjustment    I used this https://au.gktech.com/products/r33-gts-t-skyline-braided-clutch-line?_pos=2&_sid=22b01b9b9&_ss=r Also when adjusting peddle leave a bit of play. You can get into a over stroke condition easy.. Make sure you can push the slave forward after adjusting to confirm fluid can return to master then you will need to pump it up heaps…..not sure why but that’s how it is.    last thing the splined adapter is machined perfectly. If your input shaft is old like mine was I would put a bit of valve grinding paste on it and stroke it like a 15 year old. Just to give it a tad more clearance and to better match it to the spline.    reason is on a near flat shift I have had situation where the peddle returns a millisecond after you lift from the clutch. No slip or anything but I reckon this is due to tolerance on the spline being way tighter than stock clutch and binding for a sec. I think this will go away but also my spline was old. Box is old so I guess I should have checked better. It’s a super neat fit.    it feels light as and holds awesome without any noise
