Question about 1994 Chevrolet Camaro

1 Answer

Vacuum leak Can I determine where the vacuum leak might be, going by this info: The car started making a high-pitched whine that began suddenly when I downshifted this morning. (of course it may or may not be related, I know). The sound is constant, EXCEPT when I am pressing on the gas pedal. It stops then, but resumes as soon as I let of the gas. Is this more likely to be the manifold or something worse in terms of labor costs? I am told it will be either less than $100 or more than $500, depending on where the leak is. Seems that someone could figure it out before taking the car apart, no?

    No, the sound is clearly coming from the area of the manifold.

SOURCE: car is squealing and whining in front of engine. Can you help?

It sounds to me as if your serpentine belt and/or belt tensioner is bad,
I had a similar problem on my s10 and replaced belt,idler & tensioner.
All three pieces ran about $80.00. I did the work myself. Hope this helps.

SOURCE: Loud Knocking when pressing on gas pedal

What you are describing sounds like you have an engine bearing failing. Do not drive it 'till you have it diagnosed and repaired (most times though it's too late when you hear it.)..... Outside chance it could be the trans flex plate but I doubt it.

Timing belt noise


You likely have a bad/worn

Random vacuum whine from the engine compartment


Most likely it is a vacuum leak or if you or you have had some one working on it has crossed a vacuum line, also back on the intake and exhaust manifold and around the turbo you will have a couple of vacuum controllers and if they have cracked or broken then that as well will cause the noise. There should be a Vacuum diagram in the engine compartment use it to follow the lines, this will allow you to track down the leak, inspect all of the lines they are bad to crack . Also you should check the belt pulleys and belts to make sure that one isn't going bad. it will help to have someone to assist for tracing down the vacuum lines are or can be tedious and they can rev the engine while you search.

I assume that you have a 6cyl engine, noise came from both worned secondary timing chain tenssioner shoes, just replace those two and while you have them all apart, also replace main tenssioner and guide, then all noises will go away. Good luck!

High pitched whine


The most common cause would be a defective power steering pump.

Engine makes whining sound


Take the belt off and spin all of the pulleys. the bad component should be obvious. high pitch whine is usually alternator bearing for the 98 3800 its timkin part# 100ccab or it can be the power steering pump(but the pitch will change as your steering if it is that) water pump, idler and tensioner pulleys(if you have to change either one, replace the tensioner itself). if you have the supercharged model there are a few parts that can whine( or the s/c is low on oil.)

I have a 2005 Mercury Montego. It is making a high pitch whining sound when the engine revs. It is louder when going up hills or when the engine is reving harder.


first thing to check is proper tension on all the belts, if they seem good and not worn,, check for vacuum leaks , a bad hose, or one that has come disconnected will cause this too

It makes a high pitched whine at about 62 mph


Vacume line off of transmission won't alow high gear and at that speed the tranny starts screaming for relief. Find the vucume line and make sure its good and connected at both ends

High Pitch whine during acceleration


Hi Pullerwife,

I have a few suggestions for you,

First of all, check your air filter, make sure its clean, not clogged, and doesn't need to be changed.

I don't know how handy you are, but if you are fairly handy, check the idler pulley bearings, if your not, have a shop check it out, as a last resort.

Power steering pump/fluid being low is also a possibility, but thats usually more of a lower pitched whine then what you describe.

You say once the vehicle is warmed up, the whining stops. Does Weather seem to be a factor as well?

Hope I've helped, and don't forget to rate.
