Ford - Aviator :: 2003 - Hissing Sound Near Rear Of Engine?
I have the '03 Lincoln Aviator 4.6 DOHC. It has a noticeable knock/ping/chatter and somewhat sluggish acceleration. I notice the PCV hose was collapsed and shredded. I replaced the hose and valve, didn't change idle or acceleration and I still hear the hissing noise in the same region. I unplugged the EGR valve and started the truck, the idle was the same as before I unplugged the valve. could a bad EGR valve give a vacuum leak that is hard to detect? I tried testing for leaks by squirting starter fluid near the suspect areas, and I couldn't detect anything.
could a bad PCV valve be caused by a bad EGR valve and/or vise versa?

View 10 RepliesCaravan/Voyager :: Hissing Sound After Turning On Rear AC
I've got some trouble with my 2010 T&C Touring and the A/C system. I believe it is specific to the rear, but not 100% sure yet.
Here's the symptom, while driving home a few nights ago, I noticed a hissing sound from somewhere under the dash. Research led me to believe that the r-134a was low, so I bought a few cans and charged it up. I drove around yesterday with the fresh refill, and all was well. This morning, I noticed that I hadn't been running the rear A/C, and thus, not doing a full test.
So, I turned on the rear A/C and within just a few minutes, started hearing the hissing sound again. Flash back to a couple of weekends, I replaced brakes/rotors and while inspecting after taking a test drive noticed some water pooling up under the rear passenger side tire. I checked it out, but at the time, it didn't seem significant until today when I started to put this all together.
SO, my question is, what would be leaking right above the tire? Is this something that is super common and I could somehow convince my local dealer to repair out of "good will" like was happening with the '06 model year with a similar issue? I've had to do brakes, rotors and as a result of not knowing that Chrysler calipers can't be pressed in, but instead must be wound in, replaced calipers, and also an EGR valve all at the same time. So, needless to say, I'm not excited about doing further repair.
Touareg :: Hissing Sound Coming From Rear Windows When AC Is On?
Noticed hissing sound coming from the rear windows when the AC is on... It's very annoying so I always crank up the volume of the music. Funny thing is when you open one of the rear windows slightly and the sound is gone. I thought it was from the roof rack but it's not.......coz the sound is there when the car isn't moving too.....as long as the AC is on.....and the rear windows are closed tight.....

So I ended up removing my rear seats of my 2010 hatchback gs, but there is now a hissing sound coming from the rear where the seats were. The sound starts as soon as I start the car up until I shut the car off. I'm assuming that this noise has always been there just noticeable because of the seat removal. Is this just the fuel pump?

Well I've just noticed something quite annoying today... a very slight hissing sound coming from under the rear end of the car. A friend I drove to work this morning even said "what's that noise?".... It reminds me of the sound you'll hear when there is a pinhole in a joint weld, or a clamp is loose? My car only has 2800km on it!

I'm hearing a weird mix of hissing and ticking sounds.
I captured ONE loop of the sound on video, the sound loops and loops and loops at idle.
My car has just under 40k miles on it. I was wondering if this sound is normal at idle? Or if I should get it checked out.

View 2 RepliesGolf IV / Jetta IV :: 1.8t Turbo - Hissing Sound When Accelerating
There's this 1.8t gti I'm buying this week from a family member and we've been trying to solve an issue that we ran into. When accelerating the car there is a hissing noise, safe to say that it is air. Then when accelerating a little harder and you feel the turbo pulling you everything seems fine. But a second or so after , the turbo dies off and so does the hissing noise. Then I can let go of the gas and repeat the process and it happens again.
My issue is that I cant figure it out since I Need to be driving to hear the hissing and the turbo cut off. I looked around the threads but nothing really seems to match my issue. No codes either. On top of that I've never owned a 1.8t and don't know much about its turbo.
Nissan - Sentra :: Ran Over Chunk Of Ice - Hissing Sound While Engine Is On?
I ran over a chunk of ice at about 15mph. I could definitely hear it scraping the undercarriage. Now, when the engine is on (regardless of RPM), there's a hissing sound (like air escaping, or a belt sliding against something) coming from the back right side of the undercarriage. What I damaged? No smoke, no leaks... just the hissing sound.
View 15 RepliesGolf IV / Jetta IV :: 2000 - Hissing Sound Coming From Bottom?
Ever since I bought my 2000 mk4 golf I've had this super loud hissing noise coming from the bottom of the car. Almost like someone is spraying compressed air when your foot is on the throttle. Sound gets louder the more you depress the pedal. Had a catalytic converter code so after a few months I bought a new cat, welded it on, and the sound fairly went away. Still present, now months later the sound is now a bit louder but It's gotten on my last nerve, I want to fix it but I can't seem to figure out what that noise is.
Almost sounds like my car is a classic beetle by the way it accelerate at times. The car is sort of sluggish than normal at times, no codes, no lights, sometimes peeling out in 1st gear the car hesitates like I have regular power, then I have this sudden burst of 1 second power then back to normal until I shift then I never feel it again until I'm back in 1st and WOT it. Car does smell like gas a little sometimes, not too prevalent but nonetheless noticeable especially going in reverse. My gas meter seemed to fluctuate at times, I may have a bad pump maybe, not sure if that has anything to do with it.
Golf VI R :: Hissing (similar To Turbo Spool) Coming From Rear Of Car
My car is Stage 2+ (mods are in signature). I noticed today a hissing noise coming from the rear of the car when my music was turned off. The sound is very similar to turbo spool but I'm 100% positive it is coming from the rear of the car not the bay. The noise does not show up until I hit 3rd gear and from then up it only makes noise when I'm accelerating. Under any load the noise stays the same. I can accelerate slow or accelerate a little harder and the hissing noise remains constant. The only two things that I can think of are the flapper valve on the SPM exhaust and the rear diff. However, I don't see why the flapper valve on SPM's exhaust would be affected by a certain gear.

Was driving back home and the check engine light came on, these are the codes I got:
P0345: Camshaft Position Sensor "A" Circuit (Bank 2)
P0365: Camshaft Position Sensor "B" Circuit (Bank 1)
P0390: Camshaft Position Sensor "B" Circuit
The car drove fine, didn't feel any power loss, I heard a very very low hissing sound but I honestly don't even know if it was always there or not... I did put some gas from a different station for once, so I doubt the fuel caused this?

I changed my fuel filters a couple weeks ago. When I opened the hood the other day i noticed a kinda hissing or sucking sound coming from the engine mounted fuel filter. I've watched epics video a couple time and think his made the same sound but not sure. I am just paranoid with all the hpfp problems. It runs fine and had no long starts or hesitation at all. Lemme know if you all have the same thing. I just can't remember if it sounded like that before. I have done the air purge properly and several times since changing the filters. I notice the sound while doing the air purge procedure with engine off and key on.
