Squeaking rotary noise from engine

Common Car Noises and Their Likely Causes Noise More Details Likely Cause Fixing It Clicking noise while turning Starts faint, gradually becomes more noticeable until very loud Failed outer CV joint (constant velocity joint) due to torn boot (most likely) or old age Replace either the whole axle assembly (recommended) or the outer CV joint Water pump noises Difficult to diagnose because of water pump's location Noise usually caused by damage to the bearings in failed water pump Only cure is replacing it. If possible do it at the same time as a timing belt replacement to cut down on labor costs Squeak or squeal from an engine belt Loud, high-pitched squeak or squeal Belts either need adjustment or replacing If belts only squeak when damp, they probably just need adjustment. If they squeak constantly, they probably need to be replaced Exhaust heat shield noises Rattle that you hear when car is idling Damaged heat shield Replace heat shield

Hi Tim:
Possibles:
- Engine running but vehicle stopped. - Fan belt or bad bearing in rotating accessory like alternator or water pump.
- Vehicle moving - Worn brake pad. Little metal tab drags on disc and makes squeak to tell you it's time to replace.
- Vehicle not moving, engine not running - Tire parked on neighbor's cat's tail.

Try belt

If your Mazda Tribute's engine has a rumbling noise when you start it, this is most likely from the drive belt. You will need to replace it.

sounds like a glazed belt on the engine

i have a similar problem. a squeaking noise, sounds when i start the engine, and when i stop the engine. at times it comes when the engine is running and idle, and it lasts some time like a high pitched whistle. Ive had several mechanics look at it, and it seem to be one of the smaller pulleys that the belts run around. in the 2002 model (petrol) of the crv the belts are not the cam belts, becuase this model has a cam chain (much more robust!). so they all said its nothing to worry about. you can try having your pulley replaced.

Throughout my experience with Toyota's I have found that several times the hubcaps have made some weird noises. Try removing your hubcaps and driving your vehicle. If the noise still persists please let me know and I can ask u some questions and try to help you with your problem.

it could very well be just your serpentine belt is old, they usually squeak when worn. To solve that you can buy a spray at any local autoparts store to stop the noise for good, its called belt dressing. a slurping noise could be a range of things, the most common is your 
a/c isn't fully charged with fluid, the noise your hear is the compressor trying to pull more fluid in **** only getting air, hence the slurping

sounds like you have a pad rubbing on a disk/rotor, if you jolt the brakes does the noise go away? if so it's probably a pad loose

I assume that the noise changes with engine RPMs, not vehicle speed since you mention washing down the engine - something pretty hard to do if the car is going down the road-
Is it possible that what you describe as a squeak is instead a whistle? The symptoms you mention related to water could mean that an intake manifold gasket (or another part of the intake system) has a bad gasket and is causing a whistling noise from air being pulled in where it shouldn't happen. If the failed gasket is allowing water into the intake system, that would explain why the engine sounds like it wants to die. 
You might take a 2-foot length of vacuum hose or similar, hold one end to your ear and move the other end around the engine to see if you can more accurately isolate the source of the noise, be it squeak or whistle.    Obviously, don't hold the hose too tight in case you get tangled up with a belt or rotating part.
Good luck-
