Saturn - Engines - Sl :: 2000 - Loud Knocking Noise From Engine - Tow / Drive?
Oct 30, 2011
We have a 2000 Saturn SL2 (120,000 miles). Last night we drove to L.A. and back (from San Diego) , so about 250 miles round trip. For the last 45 miles or so we had the radio on quite loud. At some point in that 30-45 miles the engine developed a very loud knocking noise - like rocks being spun in a tumbler - which we noticed when we got off the free-way and turned down the radio.
This noise did not effect the way the car handled as I did not notice anything when the radio was up. We have been listening to a lot of sounds and I am concerned it could be a Rod Knock - it sounds a lot like this [URL] ... from inside the car, outside it was more of a constant pinging/thunking noise - less gravel sound.
So my quandary is this, our mechanic is not open Sundays so I cannot ask him, but when we take it to him tomorrow, do we drive it or tow it? If the rod is starting to go I do not want to inadvertently do more damage by driving it. The mechanic is 8-10 miles away. We can get their either on the freeway or through surface streets.

I have a 2000 Lexus RX300, with over 200k miles. The motor blower is making this very (at times) loud noise. To take a closer look, I removed the glove compartment to take a better look at the unit itself. I took a closer look at the blower motor itself and it looks like the top piece of the cone is cracked a little. This is where the little clamp ring is located on the tip of the cone. The noise is definitely coming from this area. I was going to just replace it, but could there be anything wrong with maybe one of the servo motors as well (Airmax or Mode)? It seems that at times (out side of the main noise) the air is not being distributed properly.

I have an 06 Beetle 5 cylinder, and just the other day, after getting a new battery and they installed it, when I'm driving and step on the gas into overdrive, it gets really loud, almost like a knocking or loud muffler that has a hole it it. However, it doesn't do this when I'm in park and step on the gas. Only in drive. It still has great power, but is loud now. I'm worried that the shop did something to mess it up, but they won't check it. There is enough oil in the engine.

I recently bought a 2007 Prius that is making a rather loud knocking noise that has me a bit perplexed. I know the noise is not normal as my 2005 does not do this.
The noise only happens when the ICE is running and the car is in drive
If the car is in park and you rev up the ICE the noise is not present. With that said I do not think the noise is isolated to something in the ICE as I think it would be present when revving the engine in park.
However is you put the car in drive and step on the brake (to keep the car stationary) while lightly revving the ICE the noise is present. The noise is present every time the car is in drive and you accelerating, even with the lightest of throttle.
It does not need to be under excessive load and with that said I am certain it is not spark knock/per-detonation of the fuel nor does it have the "pinging" sound like a spark knock.
If while driving down the road and the ICE shutdown down while driving at lower speeds the noise disappears. When the ICE starts back up the noise reappears.

Just had my 2010 F150 in for a loud knocking noise when the truck has warmed up in drive and rpm up to about 800. I can't hear the noise when I disconnect the passenger side vtc selonoid. The Tech who worked on it has recommended replacing the motor. His troubleshooting on the ticket says he removed the coil from the number 4 cylinder and the noise he hears goes away. I just can't see that the motor is bad.

I drive a 2000 Saturn S-series (SW) that has a lot of miles on it, and has been giving me consistent trouble lately--replaced the catalytic converter, transmission work, belts, coolant issues, you name it. That said, up until recently I would have referred to it as an extremely reliable car. The piles of money I've now put into it make me less likely to call it this. So, my question is twofold: a specific question and a general is-this-the-end question.
As of last night, my car has been having trouble shutting completely off. I am able to turn the key and take it out of the ignition, and the car shuts off--mostly. Something is still on (a fan, part of the engine?) and I have to turn the car on and off many times until it shuts off completely. Last night I had to drive it around the block before it would shut off. I took it to the mechanic today for a separate issue--hemorrhaging coolant--and asked them to look at the shutting off issue.
Of course, when they looked at it, my car suddenly shut off fine. They said that it probably has to do with the ignition switch, and that I'll need to take it to the dealer because my key is so old they can't recreate it from my old beaten up key from 14 years ago. (I'm not exactly sure what they have to recreate, or how an ignition switch works.) Is it time to chuck this car? Or is an ignition switch not a big deal?

I drive a 1997 Saturn SL1, 295,000 miles. Great car. Good gas mileage, very, very low maintenance. I cleaned the engine about three years ago with an engine cleaner (Gunk?). When I turned on the engine it started to make a loud noise. The best way to describe it is a loud whining noise. It appears to be coming from the AC. When I turn on the AC the noise gets quieter (but it's still annoying). The noise does not appear to have affected the car's performance, but it is loud and annoying. What the problem is?

My 2000 Toyota Corolla is making a knocking sound that gets worse when the car is in idle and in drive. I have a feeling that it is dying, but is it unsafe?

Ticking sound from the engine compartment. Here are the clues:
Have observed this since at least probably 2009. Affects a 2000 Saturn LW1 with DOHC 4-cylinder engine.
It's a mechanical "ticking" sound that seems to come from the right side under the hood.
It only happens in cold weather.
It typically starts a couple of minutes after the car is first started up on a cold morning.
It typically goes away when the engine warms up (after several minutes).
It always repeats at the same rate, maybe about 7?8 ticks per second.
It is independent of engine RPM.
It is independent of vehicle speed
Sometimes (but not always) it stops when you lift your foot off the accelerator (it may tend to do this after the engine has warmed up a bit). When you depress the accelerator it resumes It doesn't seem to affect performance but I'd love to know what it is and whether I need to worry.

So, I am driving, engine starts to knock, i stop, check oil, there is none.... I drive to nearest gas station, put in 4 quarts, still knocks but quieter. Drive back home 75 miles, knocking is incredibly loud. Had oil changed 2500 miles ago, no signs of leaking (Did they put oil in after draining? Hard to prove they didn't) By the time I got home, new oil was black. Is this an engine replacement or can it be fixed?

Lately it has been in the 20's in my area and I've noticed on the first start of the morning the engine sounds very loud and produces a "knocking" noise that lasts a few seconds and then goes back to its normal loud idle. This only happens on the first start of the day...all subsequent starts in the day are fine. (mine is a 2007 model with the FSI engine)

My car has 63 000 km and engine is making loud knocking noise all the time. Dealer took a quick look and he asked head office. Now he wants to run some tests to see which valve is bad. He's hesitating between repairing or replacing the engine. I'm really disappointed of Hyundai quality. I really hope that I get new engine instead of poor repair job.

I recently started having a very loud knocking noise in my engine and I can't place it. Mostly due to my lack of car knowledge I can only trouble shoot so far. The following conditions are what I can really only go from:.
- when I'm in park or neutral the knocking happens in about 5 beats per second.
- while idling in gear it almost goes away.
- while driving it increases in frequency and intensity the higher the rpms, until it switches gears, then its dull until I get closer to topping out another gear.
- No real functionality of the car has changed.
- I tried doing a mild brake torque, in both drive and reverse, and the engine did not move.
- the knock is pretty hard to locate exactly but seems to come from the passenger side.
I'm hoping it's not to serious because I just filled the gas tank.

I am getting a loud knocking noise from the engine on my Santa Fe. The car is very low mileage of around 51K and has regular service and oil change.
Not sure what has caused this but there is a loud tapping/knocking noise coming from the engine. Have got it locally checked with the garage and Hyundai Workshop also but both have suggested that Oil levels are appropriate and they need to open engine to investigate more.
At a higher RPM the sound becomes more loud and recognizable.

My 2009 Sonata 2.4l Sonata has been making a loud knocking noise when it is cold, but it will fade to almost nothing after it warms up. I tried to make a sound clip of the noise, but it was so distorted that I could not even make out the noise on the video.
For some strange reason the noise matches the skipping problem I have been complaining about since the beginning. Yea it's still there. It sounds like it is in the valve system, not the lower end. It leads me to believe it's coming from the valve clearance/ camshaft area.

So my 2012 plugin was parked for about 3 days, and when I turned it on, heard loud knocking and the check engine light came and stayed on.
When switching the car on or off, I'll hear two taps/ticks that were not there before. Loud knocking is not there now.
What can the issue be? It was very cold and snowing.

Fiance's 09 Corolla S just started having a rattle/knock noise this evening. car has 123k. It's clearly an engine internal sound. I believe it is coming from the cylinder head. She called me when it started making the noise, she shut it off and has only been ran enough to get it on and off the trailer.
Not sure if it's a broken valve spring or valve. or the timing chain guides? It threw a CEL light.
I ran the code on my scanner and it came back with: P0302 (Cylinder 2 Misfire)

My Dads 92 Volvo's engine is making a knocking noise and I'm wondering what the possible causes are. He doesn't take that great care of it but it didn't over heat or anything. It sounds like it is making a loud knocking or clicking noise directly from the engine when you accelerate. It still runs but definitely has a lack of power.

2002 hyundai santa fe GL2 4 Cyl Automatic ... I noticed that there is a super heavy motorcycle-ish loud noise from my engine when I put it in drive. When it's idle or in reverse or neutral the problem does not occur. but then when I switch it to drive, uber loud noise...which gets louder when I step on the gas.
What has been done so far - replaced spark plugs, ignition coils and plug wires so far...also changed the oil, no fix.
No check engine light at all.....however the battery did die due to someone leaving a light on for days So I am unable to get any code readings.

I'm looking at a dirt cheap Explorer 4.0, has been sitting for 2 years. Runs nice, with a double "knock" noise but quieter than a rod knock. Idles smooth at 600 rpm, "knock" is consistent, but increases as engine increases speed. Has 2 year old oil, and 2 year old gas. Would a tune up support it, and revitalize it, or is the engine almost dead. Still drives, didn't push it to hard. Interior is 9/10, exterior is 10/10. I have him down to 600. 4x4 works, and feels good.
