I don't have a spare car anymore, it's a custom made intake, no where to weld into. So no breather return until I make a new intake again ( number 4. And find a way to get a boost feed through a rubber hose.

Stao - it hasn't arrived yet

I... Don't understand lol.

Why is there no where to weld into? Are you saying it's made of rubber? That's even easier then man, you simply do as Sarge suggested and buy a brass nipple, heat it up so it's nice and hot, then push it into the pipe. Very cheap, and makes it's own seal.

My intake consists of a 45 degree rubber bend 2 inches of steel pipe then more silicon pipe onto the afm. In the 2 inch pipe I have my bov return, I will try to make a new one and move the return so I can fit another pipe in but there isn't much space.

Mods list, il type in order that I did them- hks high power cat back, gutted cat, k&n panel filter, spitfire coil packs, just jap bellmouth dump, just jap front mount, hypergear atr43ss1, Nissan 450cc 350z injectors, walbro gss342, nistune, z32 afm. I think that's all but maybe not.

So put the PCV return on the opposite side of the steel pipe to the BOV return? On a 2" long pipe with 3" diameter, there will be plenty of space to have two nipples.

A temporary option could be to block your bov for now and plumb your breathers into that nipple, at least then it would be somewhat driveable. May not work if the pipes are much different diameter though.

Nah I meant like every hose connection that you have made. So your boost source is running from the power steering and your pcv valve is venting to atmosphere.

gutted cat

The mostly rubber intake could easily be collapsing when your boosting, causing a big boost drop up top.

If that is a stock gutted cat your not going to get farken anywhere with it. The stock cat is a 2.5" item and that half an inch difference will hold back up to tens of KW.

Ok people. Need some ideas, what will cause 400ish ml of oil to pump out of the breather pipe in a split second.

You have a big motor spinning around, sloshing oil everywhere, getting hot and just generally making plenty of vapour needing to be drawn out.

The bottom end would normally breath into the rockers and the rockers would then have the vapour sucked out through the intake pipe using the suction of the turbo.

That circulation system is no longer there, so when your motor builds up too much presure it will pop the dip stick out and indefinitely spray oil everywhere.

Do not bother doing anything but park that car until you have put a proper intake pipe on it and sorted out that gutted cat. Make sure you hook up the breathers properly and the BOV, get a boost source from your first available cooler pipe while your at it.

The rubber bend is off a ken worth truck, I dont think it can suck shut, I covered the air box hole and it actually hurt my hand before it sucked anything shut. I realize it would suck a lot harder under load/boost but I was curious.

I understand the vapors coming out but a big stream?? If it was hooked up my turbo would have drowned I oil.

The cat is a 3" cat.

I'm doing a compression test tonight to see if the rings are stuffed.

On a side note to add to my awesome luck with cars, my wife's car is melting fuses now. Yay :(

Instead of starting a new thread, here is some symptoms any clues would be appreciated

Misses badly over 4000rpm, idles on 3 cylinders, backfires on gearcchages after it misses. runs perfectly when the tps is disconnected,

Ahh ok AFM well if that's f**ked its even worse. The factory ecu will still run the car with the afm disconnected in a limp home mode.

It will run rich and with low timing with hard coded values as well as a much lower rev limiter. With extra richness is probably what's making it smooth

I would suggest re soldering the AFM before moving on to a new one. should take half an hour and could save you a bit of money.

Number 1, your pipe could still be sucking shut at 20psi.

Number 2, if you have no crank case ventilation and the bottom end is full of gas/vapour/pressure what do you think will happen in the head? The RB's number 1 f*ck up is its oil system, it pumps too fast and drains too slow.

Putting 2 and 2 together your crank case needs ventilation so you dont get excess gas and oil sloshing around where you dont want it and it wont come streaming out the breathers.

    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
    • The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.
    • No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
    • Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.
