Ford F-150 (2004-2008) :: Weird Noise On Acceleration Sounded Like Exhaust Leak
Oct 2, 2012
Well lately I haven't driven my truck much. Usually only on the weekends if Im lucky. Well I drove it today and I noticed this weird noise on acceleration. I have the cam phaser tick and have had that for about 50k miles or so. I started to think I was getting a manifold leak and that's what I thought this noise was until when I pulled over and put it in park and revved it up I did not hear the noise again.
It only does it when you hit the gas until you get to a steady rpm. I only drove 5 miles or so. So I couldn't do much testing cause its late and I got to get up in 4 hours. I don't even know how to explain the noise. It kinda sounded like an exhaust leak but it was more of like a lite thud noise I guess. Like I said it only does it when I hit the gas when its in drive but not in park. I tried to explain it the best I could. I just hope its not phaser problems cause I don't want to dump a bunch of money into it.

Was cruising on the freeway and all of a sudden my exhaust sounded like it has a leak!!! I gave it some gas and it got louder but the car didn't pull like normal??? No check engine light or anything crazy. I don't think the inter cooler pipes blew off because the engine didn't shut down and I was on cruise mode.
Its sounds like the turbo wants to spool but cant hold boost, can this be the diverter valve leaking or its blown?? I haven't had the chance to check which diverter PN# I have but Im pretty sure its the stock OLD version. I am the 3rd owner. 07 Passat FSi variant with 36K miles.
I hear the 07 FSi are know to have bad or weak Diverters.... I know I needed to go with a stonger TSi Diverter which I hope is the problem here....

Ok I have a 2004 F150 Fx4 ext. cab. I had the truck for sale and due to something coming up I was unable to sell it. Kinda wish I did now. But anyways the truck was running great up until last week. I was drove it to work which I normally dont do. On my way home the rear end was making a weird noise. Kinda like a brake sticking. I tapped the brakes a few times and it seemed to work. Then a mile down the road it was doing it again without me trying to come to a stop and the back end was shaking. I pulled over and crawled under the truck to see if a u-joint was going bad. Everything seemed good. It never happened again until today.
This morning I hoped in the truck and went to my parents house. Its about a 5 mile drive and truck was acting fine. Came home and it was still fine. A few hours later I figured I would go up to the fire department I am on and find something to do up there. I got in the truck and didnt make it 5 feet from where I was parked and there was this bad noise followed by my whole truck shaking. It felt like the truck was going to fall in pieces in my driveway. I stopped looked around and didn't notice anything wrong. I figured I would just try to drive a little bit further and it was even worse. So I put it in reverse and it was normal. I put it in Drive again and thought my teeth were about to fall out of my mouth.
What could cause this? I know my transmission was leaking some oil from where the gear shifter comes out. I would check the trans fluid and add some if needed. I drove it up to the fire hall Monday night and did notice a slight burning smell but that was the only time I smelled it. Could it be the transmission?

I have an exhaust leak on the passengers side of my 2006 F-150 5.4 triton. If I do the repair which is the correct way to do it? Do I replace just the blown out gasket?
Do I need to buy a new exhaust manifold and gasket kit, with exactly what parts should I buy in the kit? Or do i need to replace both sides?

Truck has 107 thousand miles; had to take it in for an manifold exhaust leak. Mechanic said bolts are so rusted they break.
1) was there ever a ALERT from ford about these bolt's?
2) Thought i read ford had stainless bolts for this problem...
I've had F150's only since the mid 70's and this 04 has cost me more in repairs than ANY previous F150..

2004 SCrew, FX4, 5.4 ... I had the dreaded exhaust manifold leak on the passenger side. After reading the horror stories of this repair and living in the rust belt I decided against fixing it myself. I took it to a local repair shop to have done. Initially the mechanic could see that the front 2 studs were snapped off (before even trying to remove them).
After a full day of fighting the studs (engine loose & lifted up) everything is out but the front 2 studs. the top one has about 1/2" exposed, but it is frozen in place (penetrate on it overnight). The biggest problem is the bottom stud. it is broken off about 1/8" below the surface of the head. The guy doesnt have a small enough right angle drill to get between the frame & head to attempt to drill it out. I will gladly go buy a drill for him to do this, as it will likely save me money if it will work to drill out the stud.
Need to get the 2 studs out, particularly the bottom one, or what right angle drill may fit in there?

I have an 06 with a 5.4 with 70k on it and I have already had to do the exhaust manifolds twice, once covered by warrantee at 19k, then again around 40k and now at 74k I have a major leak from the left side manifold again

I have a Passat 1.8t b5.5 with 150hp
Some months ago I chipped it and it drives very good and I also changed the diverter valve to a 710N.
But now it is fast, but sometimes it just feels like it doesn't hold boost as it should. and I hear a very loud psss sound just like a BOV when I shift. Could it be the 710N which has been broken? Or is it a vacuum line to the DV that has a leak?

I did the flapper mod on the exhaust... pulled the hole out, put a screw in at the end of the hose and then capped off the inlet where the hose would plug into. So have doing that I honestly could not tell a difference. The car sounded amazing when turned on after sitting awhile b/c it was idling just above 1K before it went below and sounded normal.
Also, having my car next to a MK4 R32 with the flapper, the Mk4 sounded much better and louder with the same mod done to stock systems. It is very simple and to the point and with not really hearing much of a difference with it done and then a MK4 sounding 10x better got me thinking and I wanted to ask

Turbo leaking? Is it costly to fix? I have a 2002 Passat, V-4 engine. I just took it in to get my oil changed and the mechanic told me that there's turbo leak. I have also been experiencing a weird siren like noise when I drive and the car feels like it's struggling whenever I go over 40 mph and or driving up a steep hill.

I noticed the problem today when I was driving to the store. I was going around 60 and went to pass a car. As soon as I hit the gas there is a popping noise coming from the engine compartment and it had no power. It only does it between 50-65 mph.

I have a 2005 F150, 5.4 triton. I bought the truck used and it came with an Edge tuner. It's lifted with 35's.
Under mild acceleration I get a psst-psst-psst-psst-psst-psst type noise. Sounds almost like air... It only happens in drive when you get on the gas and put a load on the engine but not always. It doesn't seem to happen if you mash the pedal...
I can't seem to replicate this sound in the driveway. I've never heard this sound before.

I have a 2000 Suburu Forester the has a hole in the exhaust. I noticed today, the car became very loud during acceleration.
I plan on getting a new car in the next few months, but I was wondering if I could temporarily fix this problem with a sealant or something like that for the time being?? I included a picture of the leak.

Just bought a 2005 4.6Lused. There is a "air escaping" kind of noise during acceleration. It sounds just like the AC system does sometimes after you turn off an engine. I thought originally that it by be AC related, but doesn't appear to be. At steady speed, it goes away, but comes on again with the slightest bit more gas pedal. In cruise control, it cycles on and off when the cruise accelerates up a hill,, etc. The sound is on the driver's side apparently close to dash corner.

I recently purchased this truck and have towed a couple of times with it. It has 98,000 miles and I do not know if the automatic transmission fluid has been changed. Should I have it flushed or drop the pan and change it? I have a lift so doing the change is no problem, although it might be worth it to pay a transmission shop to do it.
Also, I hear what appears to be like a heat shield rattle or something that sounds kinda like an exhaust leak during loaded acceleration. What to look for to locate the noise? One last question, the air bag light is on sometimes then off sometimes. Any known air bag light issues? I love the truck, hate the gas mileage!

Wife is operating a 08 Escape with about 31K miles on her. She loves the vehicle but since we bought it with 24K miles on it it has had a rattle under it. I assumed that it was the heat shield and i would get around to securing it but haven't yet. Here's the question. I noticed recently that about mid way back under the pass side there is a black spot developing on the concrete where she parks every day. The vehicle does not sit and idle there. Its started and is moving in about 20 every time. I have not got under there yet but was looking for possible answers as to what and where to look? Flex pipe? Bad seal on exhaust? If this is the case should a 31K mile vehicle have this issue? The vehicle is louder than a 2.3L should be but from reading that seems normal. If it is the flex is this something that a novice wrench can do?

I was driving to work last night and too many things went wrong simultaneously leaving my MK4 stranded.
2000 Jetta 2.0
185,000
Automatic
No check engine lights or warnings
-The engine sounded like there was a hole in the exhaust at highway speed. There wasn't because it's a new system
-Low coolant light came on. The flange connector at the firewall was torn off resulting in a stream of coolant pouring out
-It was dark but the engine almost seemed cockeyed by a degree or two
-Upon parking, the motor. sounded "clunky". Driving forward seemed OK. When shifting into reverse there was a pronounced clunk and the drivetrain wasn't happy.
-I turned the ignition off and that was the last time the car started. It turns over now but will not fire up. The video I attached is my last attempt at starting it before giving up.
My car is my job and I'm at a total loss on how to proceed???

Firstly having this wired noise underneath the trunk of my car I found out stabilizer links were bad so I changed it some of the Klad Klad noise were gone but still persists then I thought it's maybe spare tire is loose it wasn't then checked the jack it's fine. It comes in very slow speed as if something is hitting ( plastic) on to chassis the rubber mounts are good not dried or cracked I went under the car millions of time in vain.

I purchased my 2008 Explorer Ltd about 4 months ago with a 4.6L and 63k miles. I use it for towing a small travel trailer, so I don't put many miles on it. It's got about 66k on it now. According to OASIS, it has had all MFR maintenance performed up to the 60k mark.
In the past two months, it has developed a "sound" on startup. it goes away after about 75 seconds. To me it sounds like a typical exh manifold leak. That "3 cylinder, putt putt putt tractor" sound. There is no apparent affect on performance. It is definitely coming from the area of cyl #1. I have a recording here.
[URL]....
It is the "higher" of the sounds. The lower pulsing/whooshing is just regular engine noise. You can hear the regular engine noise as the camera pans to the back of the car.
What puzzles me is that the exh manifold sound goes away after 75 seconds or so. Holding the tailpipe shut for a bit builds up lots of pressure quickly. Do you think it IS, in fact, an exh manifold leak, and it seals up with thermal expansion as the engine worms up (75 seconds)? Is this a typical issue with the 4.6L

is there a set of headers for my 2008 f250 5.4 rwd that will install somewhat easily without me throwing tools across the garage? I see a lot more options for the older trucks. I have a pretty annoying exhaust manifold leak and I figure I might as well throw some headers on if im gonna be in there. I really want to go for sound rather than power. I think I saw a set by flowmaster that looked decent.

I took my 2008, 56k in for a new battery after my car sat outside in negative degree temps for a few days. After doing that repair, the dealer recommended a new serpentine belt. Ever since that service appointment, the car is making a high-pitched "woo-wooo" noise during acceleration. It's definitely a noise I've never heard before. I took it back to the dealer two days later; he had the service guy drive it and they both claim the noise is normal and just due to the cold. Is it the belt? Is it the cold? Am I losing my mind?
