Just got back from a trip to San Diego. About 1700 miles in 3 days. Well I noticed today a whining sound coming from my engine area. It gets louder while the rpms get higher. And what gear I'm in seems not to matter. Anyone know what it is? Also it's been feeling a little sluggish lately. Related?

I know most V6's have a whine....mine does

 

[sp33d]

min whines right after i let off the gas... like when the rps level is going down. sounds kinda like it supercharged... heh

135k on it.

thanks charles. A lot of help.

 

[Black95GT]

lol

 

[Rellik]

sorry, but myn doesnt whine at all.

one of the pullies maybe? belt?

as far as the sluggish part its probably in your head.

I dont think any engine should "whine" normally...check some stuff.

 

[DropTop_Stang]

I'm thinking maybe oil. It doesn't sound anything like a pulley or belt.

 

[mustangmeat]

prolly that notorious idler pulley :idea:

 

[DropTop_Stang]

explain

 

[mustangmeat]

many people, including myself have complained about the idler pulley making noise, though i would probably not describe it as a whine. there is no fix for it that i know of other than buying a new one and it doesn't hurt anything. just sounds like ****

 

[mustangmeat]

if it doesn't do it when you are on the gas, or at least you don't notice it, then that is my guess. pop the hood and listen to it idle. standing in front of mine, i can tell that it is a pulley

 

[DropTop_Stang]

Okay, just did that. Weird rattle while idling, weird whine while revved. Not from the same location though. The rattle sounds like a pulley. The whine seems to be all over. How can I get it fixed? Take it in?

 

[mustangmeat]

rattle is the pulley for sure. whine could be vacuum leak or intake/cold air induction leak if it's like a sucking noise. hard to say

 

[mustangmeat]

Also it's been feeling a little sluggish lately. Related?

definitely related

 

[DropTop_Stang]

doesn't sound like an air whine. more like a grinding whine. How do I fix the pulley? Should I take my car in?

 

[Rellik]

the idler pulley would be more of a squeak.

 

[mustangmeat]

my pulley makes my engine sound "diesel like" only fix i know of is replacement. it is not a belt type squeak

 

[Rellik]

this is a bad idler pulley.
