Phaeton :: 2004 V8 - Horrible Squealing Sound Coming From Engine
Mar 6, 2010
I started up my 2004 v8 phaeton with 49k mies for the first time in two weeks and it made an awful squealing sound that seems to be coming from the front of the engine. it also seems to be idling very roughly, this may or may not be related to the noise. it has never made this sound before and i am scared to drive it until i get an idea of what it is. i am afraid it is the timing belt and the i will ruin the whole engine on the way to the dealership.

I have the 4-cylinder "I4", 2.4 L engine in my 2006 Sonata.
Yesterday, it started sounding like this: [URL] ....
Actually, yesterday it didn't sound as bad. Today I sprayed some BELT DRESSING on it, and NOW it sounds like this!

This monday i found this horrible noise coming from the engine... My first thought was a pulley bearing, yet none of them at the front appeared to be the cause, and standing in front of the bay it sounded like it came from the engine itself (which would be really bad news). Well, i parked the truck until today and i went to check if i could find the cause. I used a mech's stethoscope at the engine and found nothing strange, turned the engine off and touched the pulleys to feel if any was getting hotter than the others... no dice...
Then took the belt off and tried every pulley by hand, all worked ok, yet when i turned the Alternator's it flashed a little spark every now and then (that was just a hint, i wasn't sure). To finally rule out the engine, i turned it on without the belt (that would leave all the pulleys out of the equation). It worked fine and made no strange noises. I cleaned several pulleys and placed the belt back, and turned the engine on once again, this time keeping my attention at the alternator, enough said, it made several spark noises and suddenly, i saw a cap flying of its back. It turned out to be the bearing at the back of the alternator, it was destroyed and losing shrapnel all over, take a look:
Now, need to know what is the part number of the measures of this bearing. (I'll take what's left of the bearing to the store, but i like to be sure of what I'm looking for).

My 05 Supercrew 4X4 with 172k miles started making a horrible noise these last couple days. It sounds like its coming from the front passenger side area. The best I can describe is that it sounds like an electric tool motor with bad bearings. I'll be driving along at 45mph or above and every now and then I'll hear a really bad bearing squeal. It's bad enough that I can feel the extra friction caused by the squeal start to slow my truck down. It's vehicle speed related. I know what a bad wheel bearing sounds like and this is nothing like that. It's gotten bad enough I'm nervous to drive anywhere.

We just purchased a 2004 Phaeton V8 last weekend. We are trying to decide if this sound that we are hearing is because something is wrong, or whether that is just the way they sound. It sounds almost like a purr, like engine noise. However, it is related to how fast you are traveling, not to whether the accelerator is being pressed. The absolute best way to describe it - its like there is a playing card in the wheel spokes (but muted)!!! Its not bothersome or loud, but just odd.

I was driving the other day, and all of a sudden it started with this horrible knocking sound. I have never heard the sound before. I remember back in the day, with a 67 buick rivera, that if the oil got low, the engine would knock, and this kind of sounded the same, but more high pitched and clicky. I checked the oil first thing and there is plenty in there - in fact, I had just checked and put oil in it about two weeks before.
I have not always kept up with the oil changes, and sometimes the oil level was pretty low. My sons tell me that the sound seems to be coming from the top of the engine, and it's probably toast, a rod knock. I parked it, and figured i will get it looked at in a few months, when I'm better able to pay for diagnostics.

I've only started noticing this recently. I have a 2004 W12 with roughly 75k miles. It seems to only happen after the engine warms up, but even then its seemingly randomly. I'll notice a clicking sound coming from the front passenger side of the engine. The sound increases in frequency as I rev the engine. I have no check engine lights and no noticeable loss of power. Its not a radiator fan since the sound is still audible when the hood is open. I'm getting no CAN errors with my generic OBDII scanner (I know its not a VAG-COM but hey).
I've been reading up on the possibility of it being a bad valve lifter. I don't know much about them and was hoping to get some advice here before I go about asking my dealership to diagnose the sound. I found this random article through google vaguely talking about replacing the lifter. The person says its "reasonable and inexpensive".
I also stumbled across this thread here describing what sounds similar. Although the thread provides no closure it seems towards the end people are hinting that the engine needs to be pulled? This is contradictory to the first source I found. My question is, say it was a bad lifter, whats the extent of work required to fix it? The Parts seem to be really cheap if I'm looking at the correct stuff?

4000 miles on my CW Golf R - zero problems until this morning. WILD, Loud sqealing, screeching metal on metal or maybe stone on metal sound coming from front passenger wheel. at first i was positive it was a pebble caught b/t the inside rotor and heat shield - i took the tire off and nothing there.. Also only really does it when I turn RIGHT.

I brought my 06 in for service last week to have the creaky steering wheel fixed (under warranty or I'd have done it myself). Upon leaving my seat belt chime sounds horrible - almost like the speaker is blown. Really loud and harsh.

It always makes this sound when I first start and it is wet outside. After a few minutes the sound stops, presumably after whatever is squealing dries up.

I have a 1995 Dodge Ram 1500 5.9L truck. Originally, there was a squealing sound (which has now turned into chirping) coming from the engine, so I replaced the serpentine belt. That didn't do it. So upon research online, I preceded to check all the pulley wheels for wobble, grinding sounds. The only thing I found of concern was the a/c compressor pulley. It was making a slight grinding sound, so I thought maybe I'll buy a shorter serpentine to bypass the a/c altogether. That didn't fix it.
The chirping only happens when I put the truck in drive or reverse, and increases when I accelerate. Sometimes as I'm driving it'll stop momentarily until I either take my foot off the gas or accelerate even more. I've checked everything I could inside the engine compartment, without taking anything apart. I've had my wife put the truck in gear so that I can try to locate the sound, but I've had no luck. I don't want to take the truck in, until I can identify the problem, and maybe even fix it myself.

First off it's a 2008 Prius with 80K on it.
There is a new sound that has started coming from the front of the car in the engine compartment or even lower. It is a turning turbine like sound that is mostly obvious when driving at 60 mph, but my guess is that it is always there, but not as audible at lower speeds. The air and heater are both off and have no effect on this sound. The only thing that could have had anything to do with it is that a day or two before, the tires were low so I filled them to 40 psi. The other thing is that it clicked over to 80K the last week and the friendly red maintenance required light came on.

First, my g/f and I love her 2.0T, but lately a few things have started to bother us.
1. Strange, rhythmic squeeling at low speeds (like a bearing or warped rotors) that goes away when the brakes are applied.
2. Driver's seat is rocking back and forth under heavy acceleration and braking. I hope it's just a loose bolt and not a crack in the floorpan.
3. Check engine light randomly comes on for a day or two then goes off conveniently after we schedule an appointment with the service department.
What might be causing these issues?

What happened to my 02 mk4 Jetta after start up and engine failure.
I started the engine, and noticed a high squealing sound just like a loose fan belt, as I backed out my driveway the Battery light came on and engine died, when I tried to re-start the engine it doesn't make any cranking sound just a whirring sound.

So I just got a bunch of work done on my car: the timing belt, spark plugs, serpentine belt and water pump were just replaced. I had the oil changed, the fluids changed, new front tires, and an alignment all about a month ago, but now every time i turn my car on there is a squealing noise coming from my engine (i assume a belt). Then when i get to higher speeds the entire car shakes, but more so on the drivers side. I have also noticed my brakes just starting to squeal as well, but the shaking was occurring before that. What it might be?

I have a strange grinding sound coming from under the hood, more precisely in front of the pass side, when I lift the hood, the noise is likely coming from the part that has these two caps on top. It starts right after I start the car, stops after several minutes, just for 3-4 seconds, and than again....

I went for a tour with my truck and everything was fine, 5 minutes before getting home I heard a squealing coming from under the hood, I then lost all my gauges inside the truck. The truck didn't shut off so I drove it home. when I shut it off I tried restarting it and it wouldn't even roll over. I tried boosting it and it still won't even crank over.

My 2004 Santy 3.5L (I am the original owner) just turned 91.4K miles and all of a sudden a VERY LOUD Engine Knocking sound came from the top of the engine. I have been changing my own oil since new with synthetic Mobil 1 and a new filter every time, and I never had any issues. I changed it last week at 90K prior a Spring Break trip (1350 miles).
Then yesterday after I let her rest for 1 day, I took the kids to school and within 10 miles of my house the ticking HARD loud noise started happening. I pulled over near a shop (within 1 block of where the noise started) and they said...don't drive it it sounds like a lifter collapsed, or a rod bearing or something big...
I had her towed to the dealer and the first thing they told me is to gather all the oil change receipts and a "manifesto" and they asked me how often I change the oil... I said every 5K miles. I change my own oil and have done since day 1.
BTW, Timing Belt, Water Pump, tensioners, belts, coolant, spark plugs and coils were changed last year at 77K miles.
The car should still be covered under the 10year/100K Powertrain and I believe they are trying to build a case so Hyundai can cover this or not...
They still need to tell me what's wrong... I change my own oil so I don't have receipts for "oil changes" and I have a log of when oil was changed...

Funny pulsing ticking sound on full lock. Only noticeable when parking etc. But once it's started making it, it stops when the lock is unwound... but does it again without lock when the car reverses.
There is no feeling through the wheel or through the chasis when going forward... but subjectively it can be felt when going backwards.
Been getting a little bit more prevalent over the last thousand miles. Driving normally, steering feels perfectly normal.
I've checked the power steering fluid. If anything the reservoir is over full.. so it's definitely not short of fluid. Should the fluid be checked from unscrewing the dipstick.. or with is jut dipped in and not screwed up? Either way it's still over the max line.

Need to determine the cause of a strange high-pitched squealing noise coming from the engine compartment of my 2008 Subaru Outback 2.5l automatic. The squeal happens only when the temperature is cold (below 32 degrees) AND I hit a bump. It happens more often the colder it is outside. The noise is definitely coming from the front of the car and seems like the passenger side but I can't be sure. It happens with the blower fan/AC both on and off so I don't think it is caused by that. It happens when the car is cold or driven for a while and warmed up.
It occurs at both high & low speeds. I checked all my fluids under the hood and everything is filled as it should be. There are no lights (check engine or ABS) on. Recommend any troubleshooting that I can try? I have not taken it to a mechanic yet as they might have a hard time reproducing the noise since it has to be below freezing and hit a decent bump. I attach a video that I took while driving last week on a 16 degree day and heard the squeal when I hit a bump. I had been driving for about 30 min when it occurred. I have more videos of the noise if needed.

Still trying to track down my electrical issues. While poking around in the engine compartment near the fuse panel by firewall - i heard a clicking sound coming from the two cylinders near the fuse panel.
They are cylinders - side by side - about 1 1/2 inch wide and 2 inches tall - with electrical connections and either fuel or vacuum lines attached. What are these? Some sort of solenoids? Are they part of the EVAP system?
How long should they continue to "click" after the car is turned off? Mine kept going for a half hour. I then disconnected the left side battery and it stopped. 5 hours later after fully charging the battery I hooked it up again - and the clicking came back. Is this normal or could it be a source of my battery drain?.
