Ford - CV :: 1996 - Loud Knocking Noise In Engine
Oct 22, 2015
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.

1996 Exp 4.0L OHV ... Wife drove it the other day, said made loud humming noise, then engine stalled. Drove it this am, did it to me too while idling in D with foot on brake... humms for about 1 min, and then stalls the engine... If I rev the engine, was still doing it... but came and went when I was driving then till I got her home...
I know there is a black plastic cap that makes a similar noise but not as loud, this seems like something else... and the fact it stalled the truck is bothersome... it started up then fine, but still. The only thing that is the same as when wife had it, is that both of these days are like under 10 degrees outside... So, me thinks MAP? or something else that doesn't like these REALLY cold temps? or??

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 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.

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.

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.

5.4. So I have a 2004 F-150 that just passed 80,000 miles and a month ago it started making a very loud noise on startup, but only cold startup, meaning if I haven't used the truck in about three hours. Now I went on youtube to research and found a video of a truck making the exact same noise! Here is the link:
2004 f150 cold start knocking noise - YouTube ....
Need to verify what this is??? Some people are saying cam phasers and some are saying I'll need a brand new engine!

When you turn the interior ac temperature from cool to warm there is a loud knocking noise coming from under the dash. I am new to working on explorers but it seem like its coming from the black box nearest the firewall above the transmission tunnel. When you turn it to cold the noise almost completely goes away. The noise gets even louder when you mess with the selector for "max ac" "head and feet" "feet" etc.

2012 F150 6.2L V8... I am at a loss and I know that loud knocking is not a good sign. Two days ago my truck's low oil pressure light started coming on and off, so I pulled over and immediately turned my truck off. I called a friend at a Ford dealership and he asked a mechanic what I should do. He said it could be something as simple as low oil, bad oil sending unit or maybe something serious. So, he said check my oil level if low top it off and see if that fixes the problem. It was low and I topped it off, but the light kept doing the same thing.
Here's my dilemma; my truck wasn't making ANY noises (knocking, whining, etc...), 2 days later which was yesterday I was en route to get new oil/oil filter changed and 24 miles later I'm in a turning Lane and it dies! Will not start, but it tried, so I did not try anymore. I was able to get it into a parking lot and left it for about 4 hours and went to check on it and it started right up and that is when the knocking noise started. I turned it off and checked the oil and the level reads full...

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.

The last couple days my truck (1997 f150 4.6l) has been having starting issues. At first it would just turn over and not start then the battery would die. So i bought a new battery and yesterday now its starts sometimes but when trying to start it while its ttuning over it stops then starts turning and starts up. Then i drive wherever I am going when i get back in to start there's nothing.
Its not turning over at all but when i turn the key there is a loud single knocking noise coming from behind the dash near the passenger floor vent. Actually there ate two noise from the same area, one when i initially trun the key and another when i release the key. But after just sitting there doing this it will finally turn over and start. What this is, there are no codes being thrown besides my dreaded P0401 which i cant seem to get rid of either. Ive changed every part that has to do with the egr system and cleaned the throttle body replaced vacuum lines and still the code.

My truck is currently stock and recently started making a knocking noise louder than it usually does. I researched and have found the injectors can make a knocking noise when not performing correctly. I took it to a local shop who hooked it up to a snap on scan tool and ran some tests. It passed the Buzz test but continually failed the contribution test on cylinder 8. I'm going to go home and remove valve cover and unclip the injector to see if the noise goes away. I'm sure hoping it does as an injector by the looks of things is definitely the cheaper option. I'm scared because if I was listening to a gas powered truck and heard the sound my trucks making I would assume it was a lower end noise. My truck only has 148,000 miles....

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 just picked up a 2001 F350 with the 5.4L with 200k miles. When I test drove the thing the engine sounded fine. I got it home and noticed that it occasionally has a loud knocking noise that is coming from the Left Valve cover area. It sounds like an old Chevy 6.5L Diesel ...
It comes and goes, Hot or Cold. It seems like it usually goes away when driving with RPMs above 1500 or so, however I took off with it yesterday and the noise would not go away, it seems like it might be low on power when the noise comes on, but then again it always feels low on power, so who knows.
I have changed the plugs, oil, and verified there are no exhaust leaks at the manifolds.
Here is a video of the noise: YouTube....
I dont think it is the timing chain, as it seems like its coming more from the center of the cover, when placing my hand on the cover near the timing set there is no vibration or anything that would lead me to believe its the chain.
All of my searching so far turns up 3V stuff, and little info on the 2V engines. The valve cover looks like a nightmare to get off, who have to work on these things (including me).
