If it goes away when you depress the clutch then it is with out a doubt the throw out bearing, no doubt. Definately not the alternator, the sound wouldnt go away when you push in the clutch.E7-S14 wrote:i have a whine coming from my car that sounds sorta like a supercharger whine
a friend suggested alternator.if so does that mean my alternators going bad?
when i depress the clutch it stops.. and as i raise rpms it increases in sound and intensity
Sorry, but no, the sound is going away when he pushes the clutch down. Not the belts, not the accessories (ps pump, alternator, a/c comp) Definately is the throwout bearing. And doesnt ness. need to be changed, it wont blow to peices or anything, but, if it gets worse, then replace.zoneoneoni wrote:Look... It doesn't mean it's your alternator or any of that stuff... Check the quality of your SR20DE belts first. Second, if they're still in good condition and it doesn't seem to be the problem, it could be your power steering pump. Does your car make that "ERRRRRR" sound when you turn the steering wheel far to the left or right? Try flushing out your power steering fluid if it does and your belts are in good condition or using a vaccum pump to get all the air bubbles out of the p/s system. I don't even know if it's the powersteering but hell, that's the best I could really suggest.
When you push the clutch in what goes to idle??? not the drive belts if your foot is on the gas.When you engage the clutch the RPMs rapidly increase???? What does all this mean. Since when does the clutch determine RPM's????Space Monkey wrote:Your not necessarily correct. If it is due to RPM range then it would make sense to be belts. When you put your clutch in it goes into idle, hence less RPM's (under 1000). When you engage your clutch your RPM's rapidly increase making more noise. It could be anything. You need to define where under the hood it is coming from. Hot side? Cold side? front? back? You have to think out side the box some times.
Damn that sux, thats what I'm worried about for the OP. Theres a small chance that input shaft bearing is bad and that would lead to a broken or sheared shaft. I sheared the output shaft perfectly clean, but unfortunately I didnt have any symptoms prior to the break.xweav32 wrote:here is my 2c. i had the same whine. exactly like yours and i also had a whirring noise with the car in neutral and clutch out. well i replaced the clutch(i am a certified nissan tech btw)t/o and pressure plate. noise was still there. a week later the trans blew. it turns out i snapped the input shaft of the transmission. if you wana get really technical i sheared the connecting gear from the cluster shaft. this gear connects the cluster shaft to the main shaft. the car would only move in 4th btw.
keynotes: i had same noise, replaced clutch. noise still ther. blew up trans.
well i replaced my tranny and t/o bearing and the noise is still there.xweav32 wrote:here is my 2c. i had the same whine. exactly like yours and i also had a whirring noise with the car in neutral and clutch out. well i replaced the clutch(i am a certified nissan tech btw)t/o and pressure plate. noise was still there. a week later the trans blew. it turns out i snapped the input shaft of the transmission. if you wana get really technical i sheared the connecting gear from the cluster shaft. this gear connects the cluster shaft to the main shaft. the car would only move in 4th btw.

its a SR trans behind a SR motorSpace Monkey wrote:Arn't trannies at the junker really cheap? like under $100? Usually only about 500 to get it rebuilt if you take it out yourself and deliver it to the shop?
yeah i know.i think i just have to find a 95-96 KA trans since the SR trans is a 96 trans and motor..xweav32 wrote:the sr and ka trannies are the same. they just have diff bellhousings
