Passat (B6) :: 2008 VR6 Whistling Noise Coming From Under The Hood - PCV Valve?
Nov 25, 2013
I have noticed a whistling noise coming from under the hood. When I inspected it I notices suction coming form a small hole on the rear drivers side of the valve cover. From the little information I could find this is a PCV valve of sorts that is molded into the valve cover itself. The local dealership quoted nearly 850.00 for parts and labor. I spent a little time calling around. A VW dealer in a local city said that there was not a valve molded into the valve cover, and most likely this whistling was being caused by a hole in a vacuum line somewhere else between the engine and the firewall. This small hole is located above the where the crank case ventilation hose meets the valve cover. Is my local dealer correct in that it is the PCV valve that is part of the valve cover? Is this a fairly straight forward repair that can be done in the garage, and are there any other aftermarket fixes besides purchasing a whole valve cover?

I Have 17400 Miles on my Wagon and After Three Weeks in the Shop I am going to pick up my Car next Monday from the Dealer. I Did not have any Warnings Just Whistling Noise which was coming from under the hood.That was weary Loud Noise. I took my car to the dealer and they told it look like a bad Engine belt. After few days they told me my transmission is bad and needs to be Completely Replaced. I Read so many different stories on this Forum about Transmission Problems and i never had any problem till now.

There is a whistling noise that is coming from under the hood of my Jeep. It is more noticeable on cold days. It temporarily disappears when my foot is on the accelerator or after I have been idling at a stop sign for 30 seconds. The noise starts again when I start driving.

I have recently noticed that there is a loud, high-pitched whistling sound coming from under my hood that has progressively gotten worse over the weeks. At first, it would only occur when I had my AC or heat on and would stop immediately once i turned the AC/heat off, and will also happen from time to time when I accelerate. Now, this noise is happening right when I start my car and takes a few seconds to stop.

Usually after I run the car in manual/sport mode, I begin to hear a high-pitched 'hissing/whistling' noise coming from the engine. It sounds like a vacuum leak. It is audible while driving with the windows down.
I am having problems pin pointing the source, but it sounds like its coming from the center block. What is the right direction to the leak? It starts exactly at 1500 and cuts off at 2200 rpm (while in gear). 1500 to 3000 rpm while in park..
I have a Takeda intake installed and I re-tighten the fittings.

Can't find the PCV air inlet hose to the crankcase on a 5.4 3 valve V8 2006 F150. Most PCVs let air in on one bank and out the other bank on a V engine, but this engine has hoses going from BOTH banks valve covers to the intake manifold. The crankcase is under vacuum(8 inches vacuum at dipstick tube, 6 inches at each valve cover). There should be air flow in the crankcase not vacuum. No air is getting in which results in a vacuum in the crankcase.
Once the vacuum builds up enough after a few seconds when the engine is started the engine begins to whistle where air is being sucked in(can't figure out where) at a seal or gasket. If air could get in as it should there wouldn't be a vacuum in the crankcase and the engine wouldn't whistle. Where is the air inlet hose for the PCV system on the 5.4 3 valve V8? It must be clogged or blocked resulting in a vacuum. I can't find the hose and Alldata doesn't show it.

I have a 2004 Camry (2.4 Ltr engine) with 120k miles on it. 2 days ago a whistling/whining noise began after I had been running errands & restarted my car after being parked for about 20 minutes.
If my car has been sitting and the engine is cold (like when I get up in morning to go to work) the noise doesn't start until it gets to the 3rd line above the "C" on the temp gauge. It's a constant sound while idling or driving, except when I am accelerating. The noise seems to be originating from around the alternator, but hard to tell exactly. I have no Check Engine, battery or other indicator lights showing. Other than this mystery noise my car is running fine.

So I just picked this car up, (2000 20v turbo passat) 93k miles and I did a tune up (plugs, air filter, oil change w/ oil stabilizer, and injector cleaner) when i was out beating on the car a little, afterward I got to a stop sign, and i heard a VERY LOUD noise coming from the passengers side under the hood, it almost sounded like a loud motor, or the turbo but it was too loud to really determine... it was only there for about 10 sec then turned off but came on again about 1 min later. is this a bad bearing in the turbo? or what might it be?

Well I popped the hood to clean my air filter and noticed that the top of the engine looked to sprayed with oil mainly on/around the front of the valve cover. I haven't really "investigated" to see where its coming from. Where it may be coming from!! It has 32,XXX miles and auto.

So for the past week or so, I've been having problems with my cooling system. (May or may not be related to my air valve stuck open code, just thought I'd mention it.) First thing that drew my attention to the problem was smoke (or steam) coming from under the hood, I let the car cool off, and drove home. During this time I also noticed the heat stopped working. I went to get some coolant in another car and filled it up. Smoke went away, and heat started working again.
Later the same day I checked the reservoir and it looked low so I figured the radiator sucked all the coolant up, so I refilled the resivoir tank. I spilled a nice amount when doing that, and the steam came back. It cooled down again and no more steam, figured it burnt off. The next few mornings on my first drive of the day ONLY, I saw steam. Thought it was the condensation mixing with the leftover coolant that I spilled since it didn't happen at all until the next morning.
Today was the first time it started steaming at night, and the heat stopped working again, even though the reservoir level was mostly full. I let the car cool down, and then I added more coolant and the heat started working again, no more steam either. Looked under the hood once I got home, abt a 20 min drive, resivoir was nearly empty even though car was still warm. No visible leaks on the smaller reservoir hose but there are puddles under the hood.
I've read it could be a leak of course, but also the Cap could be preventing the right pressure to suck fluid back in radiator after expanding into the surge tank, or something causing the tank to boil over....
Car is a 2013 Chevy Sonic with 68,000 miles. Coolant has never been drained/refilled since I bought the car new in 2013.

Recently bought a 2012 gti last week, everything is great until I hear a weird whistling noise coming from the engine. I suspected it was the water pump, since i researched it and some people had the same problem. Brought it back to vw to get it checked and they said their was nothing wrong and it was a common problem.

I am having a whistling noise coming from my front axle... It only happens when the hubs are locked and in 4WD when hubs are unlocked and in 4wd there is no whistling noise... I know they are vacuum operated for the auto hubs... We just got a good snow fall the past few days and have had to have the lockers locked to stay straight... Also can I keep the hubs locked and cruise and 55 to 60 mph ? or is it not good for the locking hubs...

I get this intermittent whistling noise coming from the rear drivers side. Sounds like a coffee pot whistling on a stove. After I drive about ten or twelve miles it goes away and diminishes into a hissing noise. Is it possible the fuel pump is failing? I have a 2005 trailblazer with 105000 miles.

Got a tire rotation a two weeks ago on my new 2013 Kia Forte (purchased in August 2012).Now, I have a very high pitched whistling noise coming from the rear tire area. The sound happens at all speeds. The sound is the worse at very slow speeds; the sound is also very bad at very slow speeds when I touch the brakes and turn the wheel.I looked at back tires from outside the car (not underneath the car). The mechanical set-up of back tires look very different than that of the front tires. The back tires have metal parts touching each other while the front tires do not.

I've a new Santa Fe bought in March this year. Car works perfectly but i just noticed a whistling noise problem coming from the top/back of the car (it si located over the roof) when reaching speed of 70mph or above.
I removed the roof rack cross rails but still this noise remains. I feel it is something related to the aerodynamic of this car and the particular roof rails system. Tried to tape some connections between the rails and the car roof but nothing is changing.
I drive mostly on highway all days for work and this problem is driving me mad. I took back car to the dealer, he checkd (but i'm not sure) telling that everything is "normal"!

At the service department now... My little C started making this strange noise coming out of the proximity warning system... It sounds like a robot whistling (I don't know how else to describe it) when I'm moving in low speeds. There's also a small grinding noise like something is caught and rubbing up against something. I hope it's nothing major, but I sure am anxious waiting for them to diagnose the problem!

When I'm on the highway around 60 mph I get a whistling whining vibration sound. if I accelerate or ease off the accelerator it stops, but when I get back to around that speed it comes back. What this could be?

2001 F150 SCAB with 74,000 miles. There seems to be a whistling noise coming from the front axle. It is definately a rolling noise. I can shift into neutral and put it in 4H and still have the noise. Brakes are good, tires are fair... I just rotated my tires (criss-crossed front to back) also sprayed all of my boots with silicone spray. Still has a whistling metal to metal bearing sound. When I have the front jacked up and spin the wheels, there seems to be a decent drag turning by hand. I don't remember having much of a drag before.

My Ranger has 296,000 miles on it. Most everything has been replaced except the u-joints. It's a 2wd 2.5L with an automatic. The motor was replaced at 228,000 with a used motor with 52,000 miles. The transmission has about 60,000 miles on it. All the bearings in the rear end were replaced about 20,000 miles ago. It has the most annoying whistling noise coming from the rear only sometimes. I don't know if it's the brakes being misadjusted or a bearing with a burr in it. It happens at random times but it's such a high pitched whistling you know everyone on the road can hear it too. There is also a driveline vibration, very minor though when over 60. However, I've had the drums checked and even had the wheels balanced many times. My friend said the ujoint grease could be dried up, but the whistling noise only happens at random, the virbation is anytime you're at highway speeds. It's not a violent vibration just enough to tell that it's not a brand new truck anymore. What it could be?

I have a 06 2.0T and noticed last night when stopped at a light, a loud whistling noise was heard. When I would accelerate, the noise would go away but when coasting, it could be heard again. Is this the diverter valve? Is it easy to change?

I haven't had my 06 Passat long, but I noticed today that, when the fan is on high, there is a loud air-rushing sound coming from the glove box. I know the glove box has a little port to let in cool air (I guess to keep your owners manual cool), and when I open the glovebox I can feel a square hole with air rushing out.
I am guessing there is probably some gasket that seals the glove box to this vent hold when its closed, and its most likely not sealing correctly.
