something is making a strange noise... video inside..help

[88bonnsse]

i heard it from inside the car first so i got out and walked around the car and heard it the loudest and the most when i stuck my head right next to the passanger side front tire..

it sounds like metal but kinda hard to describe the sound.. it sounds like a loud deep squeaking noise.. so i opened the hood and its coming from the bottom of the engine somewhere on the passanger side..?


and i only noticed it in the garage with the car running in park...


i just did a lim/uim swap but that was like 2 weeks ago and i just heard this noise today for the first time


but i rembered billboost saying it can take a few months to find out if the engine is o.k or not after the uim failure..... so now im very worried..

i also noticed that the oil pressure will be close to 40 untill what ever pully starts making noise then the oil pressure will drop to the redline.. untill the noise goes away..


could anyone explain the reason for the drop in the oil pressure when the noise starts..



i noticed it more coming from the side of the alternator and power steering pump..

so i was told buy many its the power steering pump, or the alternator..

so i replaced the alternator 3 times from the junk yard ( doubt all 3 were bad ) , power steering pump, belt tensioner pulley, water pump and the belt as the original one somehow shredded into pieces while i was driving...

here is a pic of the oil pressure after the car warmed up for about 10 minutes...

and here is a video of the sound my engine is making... its gotten very loud and worse and more consistint then yesterday also.. now its harder to tell whats making the noise.. you can hear the sound the best towards the end when i close the garage door...

thanks for the help club...

and here is what i did today.

so i got the belt off and played with all the pulleys..

the ac pulley ( pulley on the bottom all the way to the right ) makes a sorta light scraping sound when i spun it with my hands and also the water pump pulley has about 2/16 of an inch play in it.. ( i can wiggle it very very little with my hands.. but i could not tell what was bad so i put the new belt on and its still making that ame loud noise again... i dont want to ruin another $30 belt..

well i grabbed a junk yard alternator and low and behold it also made a loud noise but way louder then my original alternator... so i went back and the guy was nice enough to let me exchange it for another if i could find one.. so i did. i went and grabbed another 140 amp from an 97 se and now all i have to do is try it out but i will do that after dinner at about 9 pm. so i will post back up with the results about 9:30 pm or so..

well i have some sad news...

when i put in the 3rd alternator it ran quiet and all pressure and voltage was up where it should be.. i went to the autopart store to buy some turn signal bulbs as one of mine were burnt out.. so i bought some blue ones ( for the clear corners ) and my friend that works at advanced auto asked me to turn the car on so he could see the blue lights...

well as soon as i turned the car on it started making the same exact identical noise that i first had before i started replacing everything....

and the sound stood the same as i stepped on the gas.. and with the second alternator as soon as i installed it i started the car up and it made a very high pitch whining sound and it got higher qand lower as i put my foot off and on the gas..

is there something im missing here..

is this a conspiracy ?

can somebody please tell me if the noise could be from something i might have done wrong while doing the uim...

please i need more ideas as i cant afford to keep replacing thoings hopeing to get lucky...

Sounds like the noise I had before the a/c compressor pulley seized. I didn't have any oil pressure problem though.

[azu]

When that baby went I lost a belt and harmonic balancer as well. I heard your video again and it definitely sounds like a bad pulley bearing.

[wjcollier07]

But with that kinda oil pressure...you might want to make sure you're not spinning bearings.

That sounds like a tight rod bearing... Almost sounds like the Oil pump and bottom end are total history

what do you mean the oil pump and bottom end are history...?

is this a very very bad thing,,?



did you catch the part where i stated that my voltage and oil pressure will only drop once the noise starts.. but when the noise decides to go away then the oil pressure and voltage go back up to normal....


i also forgot to mention that the engine sounds like it does not run at a steady pace..

it almost sounds like it is dieing and coming back to life, dieing and coming back to life, dieing and coming back to life..

like the idle is going up and down up and down...

make any sense.?

[88bonnsse]

can someone please give me more ideas..

its making me go crazy for about 3 weeks now and i cant figure out what it is..

i replaced the alternator 5 times already, i replaced the belt tensioner pulley, the power steering pump, and water pump..


now when i bought the power steering pump it did not come with a pulley as they said its a dealer only part..

so i was wondering if the new power steering pump that has my old pulley could be making noise from the pulley.

i would say no its not the ps pulley because the bearings are not in the pulley they are on the ps pump itself..

but what do yous think about the ps pulley making noise itself and not the bearins on the pump./.?


its very annoying and i am really starting to hear it in my sleep...

the worst part is when ever the noise starts ( which is 2 minutes after i start the car ) my oil pressure drops to the redline and my battery voltage drops down to 11.5 volts at idle.. i almost ruined all my amplifiers by letting them hit such a low voltage so i had to dissconnect them all for now...


please help me with your ideas and thoughts... please listen to the video again in the very first post and let me no what you think..

what causes my voltage and oild pressure to drop so much...?

[Cooey]

i think you found it when you said the AC pulley makes a scraping sound. Did you see metal shavings around the pulley?
The pulley bearing could be bad AND when the compressor is off the pulley may be rubbing on the ac clutch. So you would have noise all the the time but less when the ac compressor is running.

And at idle the friction of the bad bearing makes idle poorer resulting in low volts... this part I 'm really guessing at.

[putertopia]

Seeing the oil pressure, the first thing to hit my head would be hardcore motor related. Seeing the date this thread was first started, and assuming that the guy uses this as his daily driver, don't you think that the motor would be absolute toast by now? The drop in current can't be explained by a bearing unless the RPMs are dipping way low, and that would be noticeable. My A/C pulley sounded similar, and also had metal shavings all around it.

Are you experiencing any power loss (as in engine) while driving it?

[88bonnsse]

no i have not felt a loss in power but the car does shake in the steering wheel at speeds of 60mph or more..

my ac compressor is not making the noise.. its coming from the powersteering pump/ crank shaft area..


here is another close up video of the sound with the camera next to each pulley.

[myfirstbonnie]

Did you take all the belts off and then start it? If the noise is still there then it would be an engine problem. With the belts on did you engage the AC clutch?

[putertopia]

^^Note not to run it too long as it will overheat with no coolant flow, but that's a good idea.

[88bonnsse]

yes i took the belt off and the noise completly disaperaed.. put the belt back on and there came the noise again..

and the noise stays the same when i turn on the ac...

if the noise went away then its not something inside the engine. start checking your pulleys to try to narrow it down to the one causing problems.

i,ve been trying to narrow it down for 2 weeks.. and honestly it sound to be coming more from the power steering pump alternator area more then any where else .

2 weeks i been trying to narrow it down and all i can come up with is

[myfirstbonnie]

the ac pulley ( pulley on the bottom all the way to the right ) makes a sorta light scraping sound when i spun it with my hands

Right here is the first thing I would suspect.

it is gaurenteed not the ac compressor..


im almost positive its something to do with the power steering pump as thats where its coming from..

i put a new pump 2 weeks ago and the noise still did not go away.. i used my original pulley as the pumps dont come with pulleys the pulleys are dealer only parts...


could the noise be coming from a fluid line or something... i still have power steering fluid all over the bottom of my car..

i washed my car but i dont drive it in the rain so im not sure if all the fluid im seeing is from when i changed the pump or if something is leaking..

i will have to wipe it clean and see if it gets wet agin..

any ideas or suggestions..

yes i took the belt off and the noise completely disappeared.. put the belt back on and there came the noise again..

That narrows it down to a pulley!!

Why do you say it is not the AC compressor...guaranteed?

Was it making the noise before the PS pump was changed?

Make sure the clutch is engaging on the AC compressor when it is turned on.
With the belt off, turn each pully by hand and see if they feel different.

i say its not the ac compressor because i stick my head thru the wheel well after taking the tire off and my ears hear the sound 100 times more and louder next to the power steering pump.... and the sound weakens alot when i listen my the ac compressor..


and how would i make sure the clutch is engaging .. i never use my ac...

and i took off the belt and turned each pulley..

they all spin fine and for a few seconds.. execpt for the power steering pump pulley.. i spin it and it stops dead in about 2 seconds.. and the rest spin pretty freely...

and yes i had that noise before i chanegd the p/s pump..
