Hi All, Im not sure if this is the correct place to post this thread but i havent been here for so long and the entire site has had a overhaul.

Ok the problem is, when i take of, 1st gear, the car will gradually increase in a loud sound, at about 2500- 3000 rpm, it becomes very loud, a bit like what it sounds like when you initially take off when the car is still a bit cold. I have always had this sound when i use to take of and the car was just warming itself up. The sound actually over takes the sound of my K & N and the factory BOV, not totally over takes it but it halves the original sound.

But now its a constant annoyance at the rpm that i mentioned about 3000. It doesnt only do it in 1st, 2nd and third are pretty much the same only slightly less loud. 4th and 5th i dont really hear too much of it.

I dont think its the exhaust, although i have on of those silent exhausts, it isnt very loud at all so it could have something to do with it.

Sounds a bit like the old ford falcons, big windy sound.

Well i hope ive explained it well.

Any help would be greatly appreciated.

Cheers guys!

That's the worst explanation I've ever heard :D

Is it a sucking sound? Check your air filter it might not be cupped/tightened properly. Check your air intake pipe it might have loosened from the turbo.

Is it a big boomy sound? Check your cat and exhaust a screw may have loosened from the dump pipe or near the cat.

Is it a grindy noise? No idea check everything (could be the gearbox/wheel hub/engine who knows).

Does it do it when you rev in neutral ?

More info :P

I think it could be your engine fan. If the clutch on it seizes it stays on full time and starts revving with the engine causing a 'windy' sound. To check open your bonnet and rev your engine, if the fan is stuffed you will feel the breeze, your hood lining will probably show some wear too. If this is the problem, the vl turbo fan clutch fits and can be had reasonably cheaply.

i agree. the clutch fan on my falcon seized and was "windy" as all fu(k

I have also had this problem on my R31, seen it on a few other cars too.....

when the car is cold and engine off, turn the fan in the engine bay... if it turns very easily, it's fine, otherwise, the clutch on the fan is gone

in case you don't know what the clutch is, it is the the thing the fan is bolted on to.

Hi, It sure does the same thing in nuetral, Definately not the turbo spooloing :-)

I had a look at the fan yesterday, it has a slight freeplay of about the length of your palm, other than that it pretty solid.

I will check the piping and K & N.. etc and get back to you guys.

Cheers!

hi, sory to hijack

i have a tip (dont laugh!!) and it also makes a big vacuum cleaner windy sound above 3000rpm on 1st. I have a stock airbox/airfilter so its suppose to be fairly quiet. Not sure if its the turbo spooling as its very loud (well quite).

to check if its the fan , do i just chuck it to N and rev? I dont think it makes a sound then though... so maybe its something else?

how would you define turning easily?

i tried turning it and it turns pretty easily but it doesnt move alot ... err. what i'm saying is when i try to spin it, it spins like 10-15cm but its smooth action.. i.e it does not do a full revolution but moves only 10-15cm.

is this normal?

edit: ok, just tried it in neutral and it still made the windy sound..better get it checked out asap

if u try turn it whith the engine off after a drive it may or may not turn depending on how hot the clutch got. (the hotter it gets, the more it clamps and the less you can turn it)

if u try turn it after it has been sitting there for a while - eg: first thing in the morning, and you cannot spin it freely continuously, then it needs changing

Hi, all the sugns seem to be pointing to the fan clutch as the other things such as piping and k & n are all fine and in place.....definately not the turbo... :-)

I will try turning the fan again today when i get home as i havent driven the car at all today so the temp for checkin should be good.

so what im looking for is for the fan to turn pretty easily right? if it only turns 15 to 30 then stops is when i should be worried??

Well sdm33 said the part comes pretty cheap so its not that bad,

Cheers Fellas

ill update 2moro.

Ok, ive checked the fan again last nite, it turns easily, i initially didnt turn it with a bit of force but when i tried it last nite, it turns perfectly......the car was sitting in the garage all day so the temp factor is out of it too.

now, what are we left with? i think something to do with the exhaust system maybe?

Dunno ?

CHECK TO SEE IF THE FAN SPINS FREELY WHEN THE CAR IS HOT!!!

Does it get louder in 2nd and third at roughly the same RPM

ie..Does the noise sound the same at 3000 rpm in every gear or does it sound louder in first at 3000 than it does in 3rd at 3000?

if the noise is the same at these rpm's then look for something that doesn't spin at the same revolution as the engine (turbo maybe)

On a sad note...it could be your main or big end bearings.

Is it a WINE-DEE noise or a WIN-DEE noise?

    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
    • Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.
    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
    • Well the articals keep saying a Q50s (Skyline in Japan) with a new Manual gearbox. I like the talk about the new looks with the round tail lights. I hope they bring back the retro look like they did with the Z
