View 3 RepliesEver 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.
The car is a 1997 pontiac sunfire 4 cyl 2.4L.When the car is turned on it makes a sound like the one in the mp3 file that I've attached. Some other symptoms I've noticed is a very slight loss of power while accelerating, and whenever I pull up to a stop and the engine gets into the idle rpm range (800-1000) the oil light comes on and the rpm dips to about 400 and sometimes the engine dies. The engine is also running very very hot, although I haven't driven the car in about 2 months and it's 100 degrees outside, not sure if that's related.
What I have tried so far is replacing the oil and filter, and adding 2/5 a pint of seafoam engine additive for 4 quarts of oil as per the instructions on the bottle. I did this because I suspected it was a stuck lifter, but after driving it for 30 miles with no improvement I'm starting to think otherwise.
As some of you may know I'm not entirely mechanically inclined and that's why I'm here, sometimes I get posts from people who insist I shouldn't be anywhere near an engine but let's try to keep those negative posts off my thread.
Recently, I was stopped in my 03 F-150 with 124,000 miles. All of the sudden one day, the engine started knocking. The knocking was coming from lower in the engine. After sitting for about two hours, I started it again. At first, no knocking, then intermittent knocking, then steady and after about 3 or 4 min, the knocking stops all together. Oil level has always been checked and it has never run low on oil. What on earth causes an intermittent knock?
View 6 RepliesI've had this strange knocking noise ever since may coming from my motor. I thought, it might go away if i push the car a little. But it's been 6 months, and the thing is still going hard. What I'm experiencing is kind of a knocking noise, something akin to marbles being shaken up in some kind of jar, and it is only at partial throttle. Starts at 2000 rpms and goes all the way until redline. What it could be? Engine sounds perfectly fine at idle, power is still there. MPG's are the same... I've also read a couple threads that indicate that it could be my intake manifold, I am really not that good with cars, shameful but i admit.
Btw while i was browsing found a repair manual on the net [URL] ....
When I start my 2012 prius the noise scared me. The motor shook an inch and a half first tow found nothing. It did it again drove it in nothing found could not duplicate. Third time towed and again nothing found. "It is safe to drive we can find nothing wrong". After asking for a manager and inquiring about lemon status I was given a car to drive. The service rep said a manifold would be in in about a month but the mechanic supervisor said there is no eta and we are working on it.
A week later they call the manifold was replaced and they finally duplicated the issue in one of the other three cars there with same complaint. I was getting 50 mpg until this started when I took it in I was getting 46mpg. Now after the first 300 miles since I got it back I'm getting 43.5mpg.
I have a 2006 Sonata - LOVE this car. Lots of miles on it - 180,000 well cared for and routine maintenance done. I have a knocking sound from the motor AFTER it warms up.. Drives wonderful starts perfect. Mileage good as always.
View 6 RepliesThe car in question is a 1998 Subaru Legacy Outback. Just had the heads resurfaced and new gaskets, and timing belt. Runs great. Acceleration is good, stays cool. However, it has developed an intermittent knock/tapping. it sounds like its coming from the top end of motor. I added Marvel Mystery and the noise left for about a week but came back. Is this the beginning of the end? Or could it be a small problem involving the lifters/followers/valves?
View 9 RepliesI have a 2000 celica gt... My motor is making a loud knocking noise at all time.. The other day it completely stop working. It started back after a couple of attempts... I think I need a new motor but idk... What kind of motor will fit and how much or what can I get for the car if i sale it..
View 2 RepliesWent to dealer today for rattling noise which appeared to be coming from bottom of engine on passenger side. Dealer diagnosed bad a/c compressor and had to order. This noise has been going on for past week and noise appeared with and without a/c on and always at "idle" speed. Noise would go from barely audible to very noisy and loudest with a/c on. If I turned a/c off, noise would diminish immediately; however, still audible with a/c on. Car only has 2,950 miles and a/c works fine, other than the rattling noise at times.
View 2 RepliesI just bought 2003 king ranch with a 5.4 it started burning coolant and the heat was coming on then while the engine was at operating temp would blow cold air. Then the temp gauge would start to rise,once it got to the top the heat would start to come on and the temp gauge would then go down to normal.I started by changing the thermostat which didn't work.
Then i figured it was air in the system I kept burping the truck at idle but it never worked, it kept burping while driving all the coolant out that i put in back out finally i took that cap off the one that clicks when you tighten it and replaced it with a cap that tightens down all the way and doesn't click. Every morning I check the reservoir fill it up to the proper level and so far so good.
I have a 2012 L100 Saturn with just over 189K miles (yes, it's been an awesome car). In October 2012 I both sets of breaks replaced plus rotors. About 2 months after the service, I started hearing a knocking and grinding sound coming from the bottom of the car, about 80% of the time when I apply the breaks. The car does not make the sound if idle or while accelerating. The knocking seems to be loud at times and less present other times. The grinding sounds like a large wire cable is being pulled right underneath the car.
I took it back to the break place and they replaced the Master Cylinder under the warranty. The sound went away for about a month and then came back with about the same frequency. Took it back to the same place and this time they replaced the Wheel cylinder. Sound again went away, but this time came back 2 days later. I'm puzzled because for some reason the sound seems to go away and come back when the car is serviced. It;s also not consistent, but it's there. Not sure what it could be related to if not the break job. I'm bracing myself for some really bad news as this car has been a life saver since I bought it.
I am having trouble finding an oil leak on my truck. the oil is coming out of the weep hole on the bottom of the bell housing where the cover over the torque converter is. There is no oil in the front of the valley under the fuel bowl/hpop. But there is a small puddle in the rear of the valley. I have changed all the turbo pedestal orings. Maybe the ebpv rod? But i cant see it leaking from there so im not sure where its coming from. Also have to do the front main as is leaks a little onto my lower radiator hose. How difficult are those?
View 7 RepliesI just bought a 87 Ford Ranger 2.9L v6 4x4. It has a tick to it. It doesn't stop, it doesn't increase with acceleration it stays the same. I sprayed some SeaFoam in it and It improved the performance a lot (More horsepower, better reaction to the pedal.) But it is still knocking. I have never tore apart an engine before or messed with lifters or anything. I'm not completely sure how to fix it. I know knocking is not a good thing either.
View 6 RepliesWell I replaced the spark plugs on my 2000 ranger 2.5 l . Because the tabs for cylinder 3 and 4 I had to take of the intake. After all this i go to start it and it runs fine. When I drive it up the street it starts knocking and stumbles and dies. Now it runs with some sort of knock. Should I take it to a mechanic?
View 6 RepliesExperiencing a knocking sound coming from the dash area, sounds like passenger side, when slowing down or idling. Just started about a week ago and sounds like someone knocking on wood, or a door.
View 9 RepliesI have recently started hearing a knocking sound coming from the front of the car when i am turning. It does not happen with every single turn, but i notice it mainly when i am at a standstill and go to make a relatively sharp turn and give it a good amount of gas. Now I am not trying to do a burnout or fly off the line, but its not a grandma start either. slightly more enthusiasm than your normal daily drive start.
View 5 RepliesThis start this morning on my way to work. When I took my foot off the gas I would hear a clicking knocking sound the sound slowed down as the car slowed down. Any time I took my foot of the gas this would happen. Was still there when I hit the break. If i had my foot just barely on the gas it would go way. Its an automatic 2000 Accent 156K miles.
View 20 RepliesMy girlfriend has a 2005 accent and recently the blower motor started working intermittently.. After a couple of days of it coming on and off it now wont come on at all.. After checking the 30amp fuse under the hood, and the relay they all seemed to be in good shape, I even swapped them out with other fuses and relays to make sure that wasn't the problem. I checked for power at the Motor and it has 12 volts going to it when the fan switch is on.. so I pulled the blower motor itself and connected it directly to a 12 volt source and it worked, eliminating the possibility of the motor itself being seized. Now I read up on a few sites on how to check the resistor, so I did a few continuity tests on the resistor itself and didn't see anything out of the normal.. What I should check next or what the actual values on the resistor check I should be reading..
View 1 RepliesThe last issue I have to tackle with the GS450h is a knocking sound coming from what seems the front wheels and mostly the right wheel. This is when driving over a ditch or uneven road like a cobblestone road.
This issue was present before the RSR down sus springs were installed (i.e. in factory setup) but has since gotten more obvious, probably due to the more rigid suspension. Initially I thought it may have been the brake pads, however when braking harder (beyond regenerative braking system) it remains present. So I think the brakes can be ruled out.
The suspension and wheel setup have been checked by the Lexus dealer three times now and by a suspension specialist. None of them could find a thing wrong with it. What it may be?
