Noisy Start-up

[NISMO]

hey Guys,

When I start the car up and the engine is cold, I get a really loud screeching, screaming noise from the motor which is getting progessively worse. Anyone know whats up?

thanks

fan belts?

or

Starter motor?

cheers

thanks Joe,

I had the belts replaced not too long ago, so I would say it's the starter motor. There's also a whining noise coming from the front as well probs from the power steering motor, any ideas on this?

does it go away when u put the clutch in/out?

if so may be spigot/release bearing or input shaft bearing (gearbox)

NISMO,

If I was to guess at it I would say that the alternator bearings are on the way out!!(these can sometimes make the exact same sound that you describe so I would check this first) But to check it you would have to remove/loosen the belt to see how easily the alternator spins to make sure!

hey guys i got a bit of the same thing with my car, when it is first turned on its has a whining noise, this goes away after about 4 mins.

and what bearing do you think will be fked if when the clutch is out there is a loud noise but when the clutch is in it stops ?? ideas anyone

thanks

[adam 32]

it can be either front end/input shaft bearing on the gearbox

or the spigot/release bearings on the clutch

rough cost on repairs ??

gawd i hope its not the thrust bearing again

my car makes the clicking noize now and then

[adam 32]

bearing noises in gearbox mean rebuilds, so better off gettin new box. roughly $800...

spigot release roughly $400-$500 because of labour involved.

There was a thread on this a while ago, but no resolution.

I have the same problem.... When its cold, you start the car, and you get a screech (intensity of sound depends on how cold it is), and it will last about 1 - 2 seconds.

I've had this prob for over 6 months now, and I have no idea what it is. As it only does it when i start the car, and the outside ambient temeperature is low, AND it only lasts about 1 second, I haven't bothered to fix it!

And no it's not the fan belts,

Doubt it is the alternator bearings, as it would do it more consistently...

Can anyone else that has this problem, please tell us if you also have a squeeky clutch! As in does your clutch squeek sometimes when you depress the pedal?

yeh my clutch squeaks for the first 20min of driving, not very loud though. i think its from outside the car as well (hard to explain) cos ive oiled the pedal inside the car, had the dash off and sprayed everything i can think of!

ive given up...

have a read through this thread adam

I'm just trying to figure out if the 2 probs are related....

Anyone else that has the noisy start up problem hav a squeaky clutch? Even if you have one prob, and not the other, please tell us, and how long yoou've had the problem.

Thanks

George

read it... im not sure if it is related though...

im goin out to my car and listen for where exactly the squeak is coming from

[Mark0]

bugger everyone has the same thing here

we need to have a skyline meet lol "maintanence meet"

we can all do our bearings and squeaks at the same time

like a dyno day

might aget a quote on getting the throwout bearing...or even get someone to look at it and tell me what they recon it is

[MegaGTS4]

Zahos,

I have a auto(Not for long though) GTS4 and I have experienced the same sound on start up (only twice so these would have been cold outside and that the car hadn't been started for one week) so I don't think that the start up noise is related to the manual gearbox.

It seemed to come from the front of the car where the alternator is located?

It also happened after I fitted a new fuel filter and had to clean the engine bay again I thought that a unsealed bearing had got a bit damp because I only cleaned the drivers side of the engine bay.

I can't actually diagnose the problem because it has only happened to me a few times and is inconsistent enough for me to leave it alone until I put in rb26.

where is NISMO?(the one who started this thread)

[Zahos]

Thanks for that Mega!

So now I'm left with no clues as to what it could be! I would think that if it were bearings that it would do it more consistently? A friend had the bearings go on his air-con, and that made bad noise consistently, wouldn't the bearings off any component working off the fan belts do the same thing if they were buggered?

Anyhow, summer is coming so I guess I wont have to worry about this one for a while!

[Mark0]

have you checked the alternator, as i have been told that they get old and start screetching

[DAHXX]

That screeching is the starter motor, u can simply open it and regrease it or sumthing, so say 2 mechanics at 2 diff places. and both deal with skylines. They say its a relatively common annoyance that causes no problems.

About a half hour job btw.
