Hi guys, Skyline and SAU n00b here so be gentle.

I got my first skyline last weekend and after popping the bonnet today I came across a small tube coming from the air intake on the top of the engine. Does anyone know why it would be not connected and why it would have a screw in the end? Also, is it supposed to be connected to the metal tube poking out (see in pictures).

Would this be linked to the idle problem im having aswell? ( I searched and found a HEAP of threads about idle problems but none that know exactly what the problem is). I attached a short movie (6mb) to show the idle problem.

Thanks for your time!

That is the vac line to the BOV.

The previous owner probably disconnected it to give you flutter (does your car flutter?)

You should reconnect it to the BOV, wont do any harm if it doesnt fix the idle problem.

Just saw ur vid...

That idle issue ur having may be the IAC valve....or its called the AAC for the skylines :

The same thing happened to me on my VR Commodore and I just changed the IAC...Although urs doesnt seem to be stalling. So maybe TPS too...???

      Belt flex under throttle

      By drifter17a · Posted

      Hi all, I’ve just finished fitting the timing belt on my RB25, following the standard procedure: rotate the crank twice, release the tensioner, then tighten it down. The belt feels tight, and you can see that clearly in the picture below I’ve heard some people say it’s actually better for the belt to be slightly loose rather than too tight, as excessive tension can lead to snapping. So that’s in the back of my mind. What I’m seeing is this:  • At idle, the belt looks fine.  • But when cranking and especially when revving (around 3–4,000 RPM), there’s a momentary flap/flex or flicker in the belt, which I’ve tried to capture in the video. So my question is — based on what you see, is this slight belt movement something you’d consider normal, or am I just being OCD? Could this amount of movement cause sync issues? Or is it just a harmless bit of flex under load?   from what I know belt flap and flex is expected when crank spins up and pull cam with it Would appreciate any thoughts or similar experiences.     IMG_7656.mov IMG_7657.mov

      I've replaced the front brakes of my NA to 324 brembos and 350z calipers: i'm going for 225/40-18 up front and 245/35-18 in the back. I have Rays 7.5*19 ET35(225/35) in the front with 5mm spacers otherwise the calipers "lock up/ won't rotate". When i use the calculator i come up with 8*18 ET30 for 225/40...... but not sure i get problems with the calipers. Anyone riding around with 18 inch. that can confirm "that it'll fit"? In the back it's 7.5*9 ET30 (245/30) with the 5mm spacers, but there is no problem with the standard small brakes, so i want to take 8.5*18 ET25 (245/35).

      Glad to hear. If possible, get your tuner to check air's to make sure everything is still where it should be.

      The problem with FB/Insta/Reddit etc comments relating to cars is simple. You get to ask a question once, and get one round of replies. For things that can actually be answered in a few lines of text, once, it's fine. After 6 hours, your original question is lost to the void. There are no follow ups, additional questions, anything. No project car is ever such a simple list of questions to ask. You need discussion.
