Volvo :: 85 740 GLE Hissing Noise Coming From Near Oil Pan

My 85' 740 GLE has been having some troubles lately, A nasty loud hissing noise is coming from near where the oil pan is and it is more prominent when i apply pressure to the gas pedal or sometimes when my foot isn't on the brake or gas. The first 5 minutes or so of the drive are fine, you hear the hiss but there are no noticeable performance issues. After a few minutes the noise gets a little louder and starts to effect the acceleration tremendously to the point where it'll take me roughly 10 seconds to hit 30 mph from being stopped.

Volvo - Xc70 :: 2003 - Noise Gets Faster And Slower With Acceleration And Deceleration

When driving my 2003 Volvo XC70, it sounds as if I am driving on nobby mud tires. The sound (rrrrrrrrrrrr) gets faster and slower with the cars acceleration and deceleration. I know that the sound isn't caused by the tires because I am running on Micheline Harmony tires which are fairly quite. I am concerned that it may be a gear going bad.

Volvo - 240 :: 1991 - Won't Go Faster Than 40 - 45 MPH?

I have a 1991 Volvo 240 Base with an Automatic Transmission. Just yesterday, I was hopping onto the highway, when all of a sudden, my car would not go any faster than 40 to 45 MPH. It has been running fine up to that point. I ended up just taking side streets, where it ran fine. I have not taken it on the highway after that.

Volvo :: 1997 850 Sedan Coasts When Accelerate Faster And RPMs Go Up

I recently bought a '97 Volvo 850 sedan. It is not a turbo. It starts up fine. It goes in reverse fine. It accelerates to about 10-15 mph fine. But when I accelerate faster than that, the rpm's go up and the car coasts. After about 20 minutes the car drives fine and it doesn't rev high. How to find what need replacing?

Ford - Explorer :: 2003 XLS 4.0 - Overheated / Loud Hissing Sound Coming Out From Under The Hood

My Explorer overheated yesterday. Found a very loud hissing sound coming out from under the hood. Let it cool off filled it with antifreeze, started it up, started hissing again. Found the thermostat had broken. Replaced the thermostat. Filled it up again. After replacing the thermostat I found out the hissing sound was coming from the plastic thermostat housing. Replaced the housing. Again I refilled it with antifreeze.

Started to let it warm up and noticed liquid dripping out of the exhaust pipe. Checked it out. Had a green color to it. Then I noticed the coolant resivor was full up to the cap. I did not fill it up past the full line on the side of the resistor. Tried removing the cap.

Found out it had a ton of pressure under it. Bled off the pressure. Refilled it again. Did not put the cap back on. Tried starting it. Instantaneous geyser. Runs like it is missing on 1cylinder. No oil in the coolant that I can see. No coolant in the oil. Could this problem be caused by a blown head gasket of a crack in 1 of the heads or in the block?

Volvo - XC90 :: 2006 - Hissing Sound And Gas Dripping

Last week during the extreme cold my 2006 Volvo xc90 dropped a nearly full tank of gas onto my driveway. I had driven each if the three sub-zero days and on the third day drove about a mile, parked for about an hour then came home to get my phone. I left the car running while I ran inside for about a minute and came out to a hissing sound and dripping gas. I moved the car away from my house and watched the fuel indicator go to empty. Once it was up on the flat bed tow truck the driver pointed out big splits in the tank. I am sure I didn't drive over anything or through deep snow. Could the cold have caused this? Did I mention the driveway is new?

Volvo :: Access To Bottom Section Of Fuse Panel Under The Hood

95 850... What is the magic trick to getting access to the bottom section of the fuse panel under the hood. I have removed the 4 torx on the black cover, then the 3 gold torx, then the screws holding down the incoming cable bunches. But no matter how hard I try I can only pull the white fuse panel up a certain amount, I can get it to pivot on the lower fuse tray, but can not seem to be able to figure out how to either pull the lot or disconnect the top part from the bottom part - so as to move the top part out the way! There just does not seem enough give in the wires....

Passat (B5) :: Chattering Noise That Gets Faster As Speed Increases

I recently had my 2002 1.8T in for clutch replacement at the dealer and they came back and said the crankshaft was bad ( the car was occasionally making noise when pushing the clutch in, they thought it was a throwout bearing) I took the car back to bring it back to an indie, and it is loud at idle and while accelerating (sounds like a chattering noise that gets faster as speed increases) It's now sitting in the parking lot. My question is, am I going to have to put in a whole new engine to fix this problem? can just a crankshaft be replaced?

Golf VI R :: Engine Ticking Noise Faster When Start To Accelerate

Two days ago I started to hear a strange engine ticking noise. This is not the normal sound of the injectors pushing fuel into the engine, i know what that sounds like. This is far louder. And when I start to accelerate, the ticking becomes faster. When I cruise at a steady speed, the engine starts to sputter until I press on the gas or brake.x I took it to my local dealer and they ran codes and did an oil change. The guy told me to drive the car around for a bit and the noise will disappear. They also told me that if it did not disappear then I am basically screwed because it could mean that "my valves collided with my pistons due to over exceeded engine speeds" I will post a picture of the code and a video of the sound.

Accent LC (2000-05) :: Thud Noise When Going Over 15mph And Gets Faster With Speed

My i40 (18 months old and already on it's 5th problem) has just developed an enormous noise (thud thud thud) when going over 15mph and gets faster with speed. If I go into neutral and turn the engine off at speed it is still there. The crazy thing is as soon as I veer or turn right it stops but when I turn left it does not stop. It's really lot and I can feel it through my feet and on the steering wheel. I am taking it into Hyundai (again) but I'd like to understand possible issues before I go in.

Avalon 2005-12 :: Rubbing Noise Starts At About 5 MPH And Gets Higher Pitched As Go Faster

Recently I started hearing a noise that sounds like something that is rotating is rubbing on something. It starts at at about 5 MPH and gets higher pitched as I go faster.

I've had the dealer and another mechanic tell me it's coming from inside the transmission.

The thing is my car shifts absolutely fine and the noise is not associated with shifting at all. It's an 07 and only has 47k miles on it! Could something in the gearbox already be damaged?

When tear the transmission apart if they will be able to run the gearbox and determine if the noise is from the gearbox?

I did make a transmission related mistake that caused the noise to occur. I was shifting from reverse to drive and I think I gassed it a little early and it lurched a bit. What this would put pressure on?

Accent MC (2006-11) :: Noise That Increases When Vehicle Goes Faster And Decreases When Slows Down

This week I noticed a sound that sounds low that increases then the vehicle goes faster and decreases when it slows down. It is not wheel bearing noise. Took a doctors type scope and put it on the pulleys listening for the bearing noise in each pulley and found my alternator pulley making more noise than usual, My car needs new accessory belts so I ordered 3 new belts and will be replacing them soon. I am hoping the noise is from worn belts and not the alternator. If it is the alternator its going to cost me 250 bucks for a rebuilt one. I'm not sure if I can tear the alternator apart and replace the part bearing part. Have to look into this. Is this normal for a car with 161 thousand klm for accessory belt bearings on items to start to go bad? I sure hope the water pump and power steering and ac compressor and ac tensioner last. These all have bearings in them as well.
