urgent help needed please :(

[hotsky]

low down is, i got car serviced on fri morn, it seemed perfectly fine, with the report saying all it needed now was a front end allignment etc...

got home from drive ins last night, put car into PARK tunred stereo off, and i could hear a fairly loudish whistling/whining noise from under the hood..as soon as i turned her off it stopped, but turned her back on and it came back again after about 5 secs..(the temp gause is always norm, i am sure of this cause i am paranoid about temp from a previous bad experince)

just took her for a burn around the block a few times at norm temp, and came back no noise at all apart from nomral, however when i switch the key off I THINK!! i heard a little slightest squel if you wanna call it but cant be sure

anyone know what this could be please..... i have to drive to adelaide tomorrow morn(moday)

i attach a pic of something that i thought was wierd but not sure if thats the way it should be or not(the little slits/holes between the pipes)

u recon they theres a hole between the intake plenum pipes? just tighten em all up abit before u drive again.

check your belts they could be squiling.

could be yer alternator belt

cos vicki's alternator belt is screwed and her car squeels like a freight train when i drive it, sounds cool tho, scares away other cars.

[hotsky]

check out the pic again, i doctored it up a bit....its the black holes bewteen the pipes i circled...i thought of the belts, i hope it is something that doesnt really matter, cause i have to go to adel

[chopobo]

oh and please check all yer wheel nuts before you go

what ever you do check the wheel nuts

make sure they are on nice and tight

you dun wanna go thru what i did

[hotsky]

the alternator thing could be it i supse, would the fact we were at the drive ins contribute to that? ie turning car on and off to recharge regullary etc..

[chopobo]

i dunno about that

but if it is the resonator belt it wouldn't matter too much since vickii still drives her car and it still runs fine

[hotsky]

hmmmm i dont know what to do, wether to still go to adelaide or not, either way if i do i think ishould get racv total care so if i do die on the way up there, i can at least get a free tow all the way back home from anywhere in aus, and get a hire car for therest of journey hehehe....this sucks, always something happens either when you have to rely on the car or you have had a good night(ie the meet) then get home and something like this freaks you out)

it sounds like the belts, check the tightness if the belts if they are hard as a rock or loose when pushing them down, thats your problem and you'll need take it back to where you did the service and loosen them or tighten them accordingly.

belts matter bro

try checkin ya power steering pump? i know they make a squeeling niose when on the way out

[Gardo]

yep i had a similiar problem on my silvia and it turned out to be power steering pump, it was hard to figure out what it was too!

My mechanic told me that if i drove it too long like that the pump might seize or something and damage other parts ending up in a big bill$$$...

So check your steering pump, if its not that then maybe waterpump?

A couple of possabilitys here:

1. Does it sound like Air squealing out? (rubber hose?) vacum type sound?

2. Or more of a rubber on metal sqealch?

if it sounds like no 1;

Check all your intake rubbers & seals, make sure all clips are tight. (keep in mind that this leak might not be noticable, but under presure or vacume it might open, a split or pinhole in a rubber seal somewere, or even pipping .)

After you have checked everything under the hood, it might pay to take your front bar off and check your intcooler and intercooler piping. If you car is running higher than factory boost, it could be possable that there is a slight "stress" fracture in your cooler or some of the pipping. basicly check everything air travells through.

If it sounds like number 2;

Go down to repco, or somthing and buy some CRC Belt-Grip and spray it on all your belts (Not too much otherwise it will make a whining/supercharger sound). this will establish weather it is infact a worn belt or, a worn part that the belt runs. eg powersteering, ac etc. if it still makes a whining sound, its then a process of elimination: look for worn components under the bonnet. eg leaky power steering?, is there a way that oil can leak onto a belt? Does it still make the noise with your A/C on & off??

Also it might pay to check your timing belt. ( DONT SPRAY THIS BELT WITH BELT SPRAY!! =)

Good luck & Hope this helps.
