Ford Super Duty (1999-2016) :: Loud Knocking Noise Coming From Left Valve Cover Area Occasionally
Aug 27, 2017
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).

My 1999 jeep grand Cherokee with 170000 miles with a straight line 6 cilinder has a knocking noise coming from the valve cover area. It is only present during a cold start and for about 2 to 3 minutes. Once it starts getting hot it stops. The engine runs fine it has lots of power and I do not have any other issues.

My 99 F250 has just recently started making a "rattling" noise. The noise sounds like its coming from the front left wheel area. The noise is constant while driving down the road, its NOT created by bumps or anything, its a constant noise while moving.

I just bought myself a 2003 F250 XLT with the V10 in it. Low miles, not beat, 6 speed, very happy with it. I noticed today that there was an inconsistent tapping coming from the passenger side valve cover. I searched online and was pointed towards the PCV baffle. I pulled the breather hose off and stuck my finger in the hole, and the baffle is indeed detached. Now I know that I need to pull the valve cover now to at least remove the baffle; is there anyway to reattach the baffle, or do I need to buy a new valve cover?

I've got a 2016 250 6.2l and am getting a popping sound coming from the transmission area. the following is what i have figured out so far. the noise is made just before a complete stop, just as the tranny down shifts to 1st and can be felt through the manual floor shifter 100% of the time and heard roughly 90% of the time. sound ranges from not audible to loud and is random in how loud it is. the only way it does not do this is if i come to a stop in neutral or i go slow enough as not to have the tranny shift out of first from my last stop. the only other way is if i do one of those long, slow rolling stops. truck only has 6600 miles on it. i will be taking it in at 7500 for first service and have them look at it ...

I'm looking at replacing the valve cover gaskets on my 02 f-250, it's a 7.3L.
Looking at them on line there are many different brands. What have you used on your 7.3L, and which has worked the best for you?

I have a 2002 F250 5.4with Air Conditioning. The valve covers are leaking and the gaskets need to be replaced. I am attempting the valve cover gaskets. I was able to get the drivers side cover off with some difficulty. For the passenger side valve cover. There is very little " no" room to get at the bolts. I read somewhere that I may have to drop the engine on that side. I will do that if I have to.

I've got a 2011 F-350, when i'm on the driving over 60 mph i hear this humming or buzzing noise coming from around the dash. It kind of comes and goes depending on the wind direction or if I'm passing a semi. Thinking it may be coming from around the windshield seal.

My 2000 f350 is leaking oil from a bolt on the passengers side valve cover. it is one of the bolts on top of the valve cover. Can I just remove the bolt and put a rubber washer under it or do I need a new valve cover?

I have a noise with my new (2.6k miles) 2000 Diesel F250 Crew Cab. When I make low speed, right turns while crossing any type of depression in the road I hear a loud knock as if the left shock is bottoming out. There's an intersection near my house with runoff depressions across the road, I almost always hear the noise when making that turn. I've occasionally heard it coming from the right side when making a left turn.

The Truck: 2008 F350 Super Duty, Lariat Crew Cab 6.4 Diesel, Off Road package with just under 90K.
The Noise: It sounds like a cross between Morse code ticking (No Morse code message. I thought of that) and the sound a styrofoam cup makes when it rubs against another cup. The noise is fairly loud. Noticeable at standard conversation speaking levels. Doesn't just go away once it starts.
The Apparent Location Of The Noise: Sounds like it's coming from just right of my center fold down cup holders between the driver and passenger sides of the dash.
Process Of Elimination: No set rule for when it starts to happen but it doesn't happen all the time. SEEMS like it happens after a longer trip.
Air conditioning on or off doesn't make it stop. Fan on or off doesn't change anything. Restarting truck at a stop light doesn't change anything.
Varying truck speed doesn't make a difference. Banging on the dash near the sound doesn't make a difference.

I thought there was a v10 specific superduty section like how the psd does, but my thread went in the "performance, engine, troubleshooting" section.
I wanted more exposure than that particular small viewed area.
I don't have a video of the noise, but my 99 f450 v10 5spd has some iffy noise coming from the front. I've read so many threads on this and they either end with "my motor had 1-2-3 bad pistons" or "my flexplate was cracked" and all that dealt with chain tensioners were never finished.
I know what piston slap sounds like (worked on many cobras and lightnings with forged pistons that had it) and have experience with bad wrist pins and broken piston skirts, and this noise doesn't sound like any of it.
Noise is a loud clicking/clunking/Detroit diesel idle noise. When you rev the engine up it doesn't lighten or get better, only worse as rpm goes up. Oil is terrible looking, I'll be getting that changed this week.
Story on truck. I've had this thing for 4 years with blown motor. I got a buddy that acquired a parts truck and he said it ran good. I dropped my truck off and he swapped the engine. I got my truck back running, but with this engine noise. He said it needs to get run some more and change oil.
I think it's timing tensioners, my buddy says it will come out of it, a mechanic friend says it's going to blow up "because they all do" and I don't really want to replace the engine again.
If it's tensioners, how big of a job is it. I have the cam clamps and crank stop and the ford tools to make sure crank and cams don't rotate while apart.
I'm just 650 miles from my truck and may need someone else to do the work. Which sucks.

I have a 98 F-150 which has a loud knocking at the passenger side valve cover. I am not a mechanic but thought it was a rocker arm knocking. I dropped some oil from the oil pan and did not see and metal shavings. I added some mystery oil but the knocking continued.Loaded the truck on a trailer and hauled to a mechanic to check for the problem. He said the oil ports are clogged and oil can not get to the cam shaft and the cam shaft bearings are probably causing the knocking. He said there is no way to fix this problem and I will have to replace the motor.
I called another mechanic and described what the other mechanic described. The 2nd mechanic said it would require a complete tear down of the motor and would be cheaper to replace the motor. I recently bought this truck just to use for hunting and around town since it already has 198k miles on it.
Is there any way to clean the gunk from the oil ports? The truck will still run but just has the loud knocking so I don't let it run for more that a couple minutes. I have been reading many opinions for sludge blocking the oil passages and am considering removing the valve cover gasket and filling with diesel and let sit for 24 hours then repeat then put in fresh oil and filter. Maybe this will clean the blocked passages.

I just got a 2003 f250 5.4 triton and it has a terrible knock. I've hear of the cam phaser problems but this thing knocks at high rpm and at idle so I doubt it would be a phaser, I thought it could be a rod bearing but I'm not losing any oil pressure. Its a pretty loud knock I don't have money for a mechanic to diagnosis it...

My girlfriends 06 Sonata 4cyl threw a p0011 code a week or so ago. I looked online and saw that it could be dirty oil so I immediately changed it (it was about 400 miles overdue at that point). I also looked on the forums here and was referred to a thread that suggested replacing the oil control valve. My girlfriend drove to work a few times before I fixed it (maybe a 100 miles total) and the car stalled out in the middle of an intersection. I then replaced the OCV and to my discontent the problem was still very present. Very loud knocking or clanking under the valve cover and sluggish idle. Her mechanic now says that it is a job for a hyundai dealership and that it could be something as bad as a head or engine rebuild. What the problem could be?

We were using my 2001 7.3 4x4 (automatic, manual lock outs) in 4 low yesterday on dry pavement in an attempt to pull out the remainder of a 6x6 post in concrete. We were working her pretty hard alternating directions of pulling. At one point we heard a loud bang (see also: thud; pop; etc). It seemed at that point that the front axle was no longer functioning in 4wd. We still had the low gearing feel, but at one point I noticed my rear tires trying to slip on the driveway, but fronts didn't appear to be pulling anymore.
Long story short, came in, went to bed, went out this morning and thought I'd jack up the front end and roll the tires in both 'free' and 'lock' to see if the universal joints (yokes?) behind each wheel were spinning or not, depending on whether free or locked in. I noticed on the passenger side a few drops of a clear/light colored fluid that had dripped from behind the dust cover that isn't functioning any longer. The joints worked as they should, based on if it was locked in or not.
I decided to go ahead and put the back axle on jackstands as well and see how it was working when "driving". When in 2wd, rear worked, front was stationary, as it should be. when in 4high, rear spun, front driver spun erratically, nothing from passenger front (where I had seen drip). 4low was same thing - erratic on driver side, at best.
So I know I have front axle/transfer case issues. The question is, with the drip (smells like grease, so I'm assuming its gear oil?) would I be safe to drive it a few days with hubs in free position? I don't want all of the fluid leaking out when I'm driving down the road. I use the truck for work and wouldn't be able to be without it until later in the week or next week. But I also don't want to drive it if it will just make my predicament worse.

I have a 2014 4WD Super Duty. It has a squeak that is coming from the drive shaft area. I had someone listen to it as I drove slowly next to them. It is a repetitive: squeak squeak squeak squeak squeak. Not loud. The frequency increases as speed increases. I could believe it may be a U joint based on the frequency, but seems hard to believe with a new truck. I heard this sound when I first got it, but the sound was so slight that I thought it was just some sound associated with a newer engine. But now it is becoming a bit louder.

I found water under carpet next to door. Appears to be coming from area above center of vehicle. Only occurs during rain etc. Not from A/C or heater housing.

I have a 2001 6.8l v10 and have nothing but problems. now i got a knocking noise and the oil has water in it. i have no clue what is wrong and on start up it blows white smoke till its warm i have looked at the coolant lvls and they have not changed. the oil pressure is fine while driving but at idle and stop lights and stop signs it drops and the light comes on. i have not had a check engine light yet? what could be wrong? i have blown plugs 5 time 3 coils and 2 head replacements. I hope its just old oil or bad oil i have no clue it is due for an oil change but would just oil oil make all this happen. I also am seeing oil coming form the intake on the throttle body but the oil breathers are right there too.
