R34 Gtt Rattle - Not Clutch - Metalic Sound. Turbo Area

[Granthem]

Pulled up at my girlfriends tonight after a short drive from my house (like 5 mins). Had warmed the car up before the trip and was just pulling to a stop when i noticed a weird sound. Doesnt go away when the clutch is in. Oil pressure is normal (i think its what it normal is at at idle)

Anyway it sounds metallic, kinda a rattle. Like when the powerballs go around in their clear sphere when the lotto is on tv lol. Its definitely from the turbo side of the engine, around the turbo somewhere. It can be heard from in the cabin (much clear then with the bonnet up), and its also clearer with the bonnet down listening with your head near the guard (cuts out the fan noise)

I did a search but nothing seemed to match what im after.

Car is manual, GTT, 60 thou on the clock. Cat back and pod, stocko boost.

Anyone else had this problem?

Its inconsistent, as in doesnt have a set rattle, it goes and comes and is not repetitive.

Maybe turbo bearing? Hopefully not engine bearing?

You gotta listen kinda hard to hear it with the bonnet up and that goes for in the cabin aswell.

Any help would be great/Ideas to try and rule out

Just sounds like a leaky manifold gasket.

Common problem, go see your mechanic for a replacement

[Granthem]

hmmm it isnt a air style noise.

Hi pitched, metal style

Like possbily a wheel touching or something while its spinning.

Its there and then not. Loud then quiet. I dunno

[R31Nismoid]

Well if you dont know then best bet is a mechanic mate.

No-one here is going to know what it is if you cant pin-point the part.

[Granthem]

Yeh I will. Its just alot of times a simple thread on here gives people a fair heap of options to look into. Thats all im after

[R33Turbo]

hey mate, check if it gets alittle louder when you turn on your head lights...and see if it goes quieter but still there with the headlight off...

[Granthem]

Ok mate will do that this arvy. if it does what are you thinking it is?

[Haines]

Wanna buy a turbo grant LOL

I have a spare R34 one here somewhere

[Granthem]

lol guessing thats pedro? might need a replacement yet!

bloody hell just my luck if i do. Its a very strange slight noise. hi pitched but metallic and comes and goes.

[R33Turbo]

so have you tried it yet grant? i only ask cuz i have the similar sound ur having hi-pitched metallic sound but very hard to hear in the open and can only hear when in an en-closed area like a garage... but the headlights on would make it alittle louder than it is..

[R33Turbo]

are you sure it even comes from the turbo area?? does it come from the right side of the engine???

[Granthem]

definitely turbo side of the engine. havnt tried it yet i got dropped to work today. didnt wanna drive it and cause any damage.

its defnitely from the turbo side of the engine though

[R33Turbo]

wheres the turbo side of the engine?

[sl33py]

Maybe you've got the powerball spinner under there! Take her to the doctor!

[Granthem]

depends what side your looking from

lol. standing from the front, looking at the engine, turbo side is the right side. from in the cabin, they turbo side would be the left side

lol hopefully its the power ball... thats gonna give me bulk money to piss the rb25 out of there!
