hi all

Ive just finished rebuilding my engine and got the car back on the road (now its off the road again cause some f**ktard ran into me :@) but I noticed that when I shut the engine off, there is a distinct hissing noise coming from the front left side of the car. I have checked all vacuum lines etc (cause thats what it sounds like) and cant find a fault.

Has anyone had the same problem or does anyone know what it could possibly mean?

Cheers guys

My car has similar sounds when you turn it off... it'll kinda hiss for a bit like there is a pressure releasing..

Makes a couple of other noices, ticks a bit than settles down and stops after 20secs or so.. I've got over it as I don't think there is anything wrong I think it's probably just the engine cooling..

Exact same thing on mine.. After a while the faint hissin noise goes away..

must be a series 2 thing..

but ive only got the standard nissan turbo.. well so I think anyways.. but the only thing is it wasnt doing it before the rebuild (forged rods and pistons + balance).  Is it anything to worry about??

mine did the same thing when I had the standard turbo.

Like a hiss whistle. I wouldn't worry. If your engine is running ok, then leave it be.

Mine is stock except from exhaust.. it still does it.. I wouldn't be too worried..

No need to worry.... as a few of you had said its just pressure release coming back through your pod. You can just sort of hear it if you have your standard air box in there, but its no where near as noticeable.

I even had a vtech civic that would hiss out the pod when you switched it off... No need to stress guys.

On the topic of noise's any1 have this on their car

After i got GFB Stealth FX BOV fitted i now can hear my turbo making a winding noise

not air suction noise. cant really describe it but i've heard the same noise on a WRX sorta like a humming only when im on boost sounds pretty cool. just wanna know if its safe

    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
    • From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
    • That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
    • I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.
    • If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
