yeah it does some crazy stuff and should probably be left alone

i've head ppl also say that you should take a boost source after the cooler and even from the manifold, i guess to counter the boost drop across the piping and cooler core

I wouldn't. What happens when you do for some reason get a massive pressure drop across the system? Most people (with a Hypergear turbo at least) will use an actuator that is rated close to their turbo's maximum efficiency. But if your turbo is efficient to 20psi and you have an actuator that is rated to 20psi hooked up to the manifold, and you get a 5psi pressure drop, then all of a sudden your turbo will be trying to push 25psi, which could lead to super-heating of the intake charge or outright turbo failure.

I would have the nipple as close to the turbo outlet as possible. Then at least if you get a pressure drop, you're just going to lose a bit of power and you will notice and get it sorted out.

There are lots of fors and againsts.

Some people claim it using manifold causes boost spikes as you run a longer actuator line as well as a longer pressure source etc etc.

I used to run my old TD07S off the manifold, never had boost spike issues, and I actually had a reason... I had no BOV, there fore I wanted my pressure source to my wastegate in vacuum during gear shifts rather then seeing the huge pressure in the cooler pipes. This forced the wastegate shut whilst shifting, and made the car come back on boost hard again...

But on a nice little street setup, I'd have the pressure source as close to the turbo as possible.

Ok now I can smell oil through my air con, anyone ever had this, I can't find a leak but yeah kinda weird.

OK, pretty simple mate.

Your AC picks up fresh air from the skuttle panel (where the wipers are), anything that comes out of your bonnet would get sucked into there while your driving.

If your PVC is rooted and letting boost into the sump then you are probably pushing fumes or oil out of the dip stick. Furthermore if you have done a half job of your oil breather system (noting you dont have it running to your intake pipe anymore) it would also be doing the same thing. Otherwise if you have a little airfilter on the end of your rocker breathers it could be that too.

Yeah I thought that, it only really happens when I brake. One day was a really bad fuel smell the next it was oil, that's what had me poking around and I can't find anything. Guessing it's just another quirk.

Reading through all this and the other crap that youve posted all points to one thing

You shouldnt be around cars cause by the information or lack of you do give us you dont even

know wat the f**k your talkin about.

"DAMN I GOT NEW TYRES AND NOW MY GARAGE SMELLS LIKE NEW TYRES"

I mean your persistant ill give you that but seriously do you even know wat the f**k your on

about?

By the sound of it all just sell the car and buy a push bike...

We can then see threads of "How do I lube my chain" or "Im stuck in 15th gear HALP ME"

yep sorry but this is getting funny now....

Why are you not just taking your car to a decent mechanic/tuner, really these issues your having don't sound that hard to fix really....

He will prolly blame the tuner for not having a clean smelling car soon cause of this oil/fuel

vapour thats leaking out...

"YOUR TUNE IS SHIT, MY CAR IS STINKY NOW :( I DONT LIKE YOU!"

Really reminds of of all the halfwits at work that find the old point and blame game alot easier

then just saying "Yes I f**ked it by doin blah blah blah"

Just sell the f**kin thing and rid yourself from this site...You remind me of a smarter version

of La Bomba.

Chocco you never cease to amaze me with your completely useless posts. For some reason you feel that people aren't allowed to learn about the causes and fixes for their mechanical problems.

For those interested it appears some of the oil drains in the head were blocked.

Come on leave the poor guy alone, he is trying to learn.

lilcrash all I can suggest is if someone offers some advise that sounds reasonable then follow it and give some feedback/results <- Which you have actually been doing, apart form the odd delay.

Keep cracking on you will sort it out sooner or later.

alot of the delays in testing is because i get stuck into working on my wifes car and forget about my own problems. her car is still running perfectly without an afm and it runs like shit when i plug it in. im very confused how thats possible but yer.

    • Looking at the photos, you could easily just drop this pipe and dump into atmosphere  Just 1 or 2 quick hits for data acquisition - if have a heat shield material and/or sheet metal, maybe just use wire/metal cable ties and attach it in a way to deflect heat from melting nearby wires.  
    • 2025 PRP GTR Festival - A Massive Thank You from SAU NSW! On behalf of SAU NSW, I want to extend a huge thank you to our incredible committee for all the hard work and dedication behind the scenes. You are the engine that keeps this club running smoothly! (hopefully an RB lol😆) To all our amazing volunteers who helped make the GTR Festival Sydney such a success, thank you for giving your time, energy and sacrificing your weekend sleep-ins. Your efforts did not go unnoticed and were absolutely appreciated by everyone. We also want to give a big shoutout to the workshops, trade stalls, and the awesome VIP's we connected with over the weekend. Your support means the world to us, and we’re so proud to be part of such a passionate automotive scene. We are looking forward to collaborating with you at our future events.  SAU NSW had our marquee up for two full days at GTR Festival, packed with merchandise, a sizzling members BBQ, and a chance to chat with the committee, sign up, and check out some hot Skylines on display from our members. It was incredible seeing so many smiles and genuine conversations, that's what we're all about! SAU NSW is more than just a car club... we’re building a community where you can make friends, share stories, and talk about anything RB related or not. 📸 Please post any cool pics you took at the GTR Festival in this thread! 📸 To our current members, thank you for your ongoing loyalty, and to all our new members... welcome to the family! We’re beyond excited to have you on board! Please ensure you are involved as much as possible within the club, and make the most of our exciting upcoming events. Here’s to more future events, thrilling drives, chill meets and good feeds! Let’s keep building something special. 💪🚗💨 Matt Zoumpoulis, President SAU NSW
    • Yes, well, keep in mind that the air is intake air, which equal boost + possible oil. If there is a fine deposition of oil/scunge that then gets hot and carbonises, it could look just like that. Probably shouldn't be leaking. Might just be normal for that product. Hard to know if it is relevant.
    • Wrapped up putting the motor back in today. I have a stainless flex turbo drain pipe like you see on cummins and that funny enough PRP started selling. I generally prefer these but sadly they come with a finite amount of times they can be bent before they snap. Took well over a week for a replacement to arrive.  I was able to prime the pump but I will more then likely wait until next friday to take it on its madden voyage. I also installed the nozzles for my direct port WMI setup but plugged the nozzle holders for now. I'll tube it with Swagelok SS tubing and fittings next chance I get. No rush, i'll be breaking it for a week or two anyways. 
    • I could definitely do some logs without the VCT enabled for sure. I believe we tried it on the dyno and it still spiked but wouldn't hurt to try again and have the logs    I might be able to use some metal cable ties and hold the gate open entirely, I'd need to see about that one.   What do we think about these marks on the cap of the actuator? This is where the two parts push together where the diaphragm spring is. To me they look like air has been sleeping past?? Specifically talking about those black stains above the lower rim/lip. They can be rubbed away as if it's just an exhaust stain.
