Subaru - Outback :: 1998 - Intermittent Knocking / Tapping Coming From The Top End Of Motor
The 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 RepliesGolf/GTI VII :: Clanking Sound On Boost In Higher Gears
I noticed this sound on Thursday, I couldn't replicate the issue at first, but it's getting worse. I can now replicate it almost any time I get into boost in a higher gear (4th, 5th mainly). Partial throttle, usually starts around 3,000 RPMs. Can't quite tell where it's coming from, but it's a bit concerning. I've got 16,000 miles on it with no mods (DSG gti). It'll be going to the dealer next week for sure, but what it could be? Kind of afraid to be driving it, but my dealer is closed until Monday and I wont be able to get over there until the afternoon.
Sound starts at about 6 seconds into the video (it's quiet, but you can hear it well if your volume is up), turbo starts spooling up at about 4 seconds. The car has a slight hesitation when the noise happens, but it's not violent. No CEL.

After replacing my brake pads and shoes I am hearing a squealing noise coming from the area near my brake pedal. This noise sometimes becomes high pitched if I depress the brake too hard. I am also losing a little bit of brake fluid if I depress the pedal hard several times. The brakes themselves function fine and have no problem stopping. When I bled the brakes today some of the fluid was black. I figured it might be air in the system but after bleeding them it is still happening. I also replaced the bleeder screws.
1997 Pontiac Sunfire 2.4L uses DOT 3 brake fluid.

View 14 RepliesChevrolet :: Engine Is Running Kind Of Rough And Has Tapping Or Knocking Sound
It is a 2002 or 2003 Chevy truck with a diesel engine. He was going down the road the other day under normal driving conditions when the motor made a racket and then white smoke started coming out of the back like a chimney. The truck will still crank and run (and smoke), and now there is a knocking or tapping noise that is coming from the engine. The engine is running kind of rough, and has the tapping or knocking sound, but it will calm down for 1/2 a second at which time the rough idle and noise stop, but quickly return. There is no engine code showing, so my code reader is useless. I once had a Chevy 350 with a spun main bearing that sounds similar, but the motor didn't idle rough or smoke. I don't know enough about diesel engines. I was told there was a possibility of a bad injector pump or bad injector itself. Is there any way of testing this yourself, or does it require a shop trip?

I have a 2011 Corolla S with approximately 11,500 miles. It has been regularly serviced at a Toyota dealership. The oil level is checked regularly and is full. Today I heard a slight but noticeable tapping sound when the motor is in the 1800-2100 rpm range. it is quiet throughout the rest of the engine's power band. Could this be a serious problem in the making?
View 6 RepliesCelica :: Knocking Noise Coming From Motor
I'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] ....
Prius (2010-12) :: Knocking Sound From Motor
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.
Pontiac - Grandam :: 2005 - Knocking Sound With Every Rotation Of Left Front Wheel
I am hearing a weird knocking with every rotation of the left front wheel and I know it is not the cv joints. I replaced the wheel bearings on the car a week ago . I think it maybe the brakes have got loose and hitting the rotor or the wheel might be loose but I'm not really sure and it knocks faster with acceleration.

View 10 RepliesPontiac - Sunfire :: 2000 - Stalls While Accelerating?
Any way, my 2000 Pontiac Sunfire will randomly not accelerate while I am driving. I was initially rolling up to a red light so took my foot of the gas at about 20 mph, then the light turned green so I tried to hit the gas but nothing happened for about 5-7 seconds. So I was just coasting, but then I hit the gas and everything was fine. It did this a second time on the way home. Two days later I went to start my car and it wouldn't start. Nothing was happening--no noises, nothing. So I got my battery tested--Autozone tested it and said it was bad, but after replacing the battery nothing happened still.
Then a "mobile mechanic" came and stuck a screw driver into the starter to short circuit it so it made a sound like it was trying to start, but didn't. Then after a few minutes he looked and my radio was on and it started with the key. Since then it has not started only one time when I used a screw driver to start it myself, but when I was on a steep incline last night it kept not accelerating if I made it work too hard. I would be at ~65 mph and it would just quit so I'd pull off the side of the road and it would drop to ~40 mph for ~5-7 seconds, then I'd hit the gas again and it would go just fine. It did this about 3-4 times. One time all the lights on the dashboard flashed on when it wouldn't go. One time it just completely stalled on me when I was driving. I pulled off the side of the road and started it again and it was fine.
Pontiac - Sunfire :: 1997 Car Is Not Shifting Gears At All
My car is an automatic 1997 pontiac sunfire SE. 2.4L. I drove into a parking space and the car would not shift out of drive into park, or any other gear. I called a tow truck and the guy said that the "link" had popped out of place and it needed to slip back in. He also said the high heat (it was 109 today) can warp the plastic to where it will not stay in. He showed me this link and popped it into place. I was able to get the car to shift from low to park and then to neutral but it popped out again. So I know it's not the transmission. My question is what is this "link" called so I can get a replacement for it.

View 3 RepliesPontiac - Sunfire :: 1999 - Odd Tugging When Speeding Up
For the last two years my old Sunfire (I've been its only owner) has been tugging while speeding up (happens at different speeds) and I have taken it to all sorts of mechanics and none have been able to solve the issue. The car had a faulty injector which was changed with a new original part, the transmission diagnosis have all come out negative, the engine is in great condition according to all the mechanics and the electromechanics I've been to have found no problems with the car whatsoever.
The car has around 130,000 miles and runs great, it just has these tugging episodes while accelerating and I have ran out of things to check in the darn car. The car is always up-to-date with maintenance and it's used for short trips the majority of time. What could be wrong with this car?
Another detail is that when the car is full (fuel) the tugging stops, but none of the mechanics have been able to find the relation between the fuel and the tugging.
Pontiac - Sunfire :: 1998 - 3rd And 5th Gear Grinding?
I have a 1998 Pontiac Sunfire 2.2l 5 speed. 3rd and 5th gears are grinding as i enter the gear. It happens when i am up shifting sometimes, but more often happens when down shifting. im not sure if i have a clutch issue or if i need to replace the transmission. I recently replace the clutch slave cylinder/throw out bearing. at the same time i flushed the fluid. How do i start to diagnose the problem?
