I have a 6.8l V10 that ..... seems.... to be knocking. I am used to hearing v8 knocks but not so sure about a v10. The knock seems to double tap sometimes. Could this be a bad valve or lifter instead? Video is linked.
Also oil pressure seems to be fine.

My 2004 powerstroke recently started making a loud knock during the process of starting. Will make the sound warm or cold, however I mostly hear it when the truck is warm as it cranks a little longer and about two seconds into the crank something starts knocking. After the truck starts it runs perfectly fine.
View 4 RepliesHave a knocking noise on my right front when I hit a hole or when the wheel comes up like when I turn I to a drive way that has a little hill the right tire hits and I hear a popping Boise sounds like its under the truck but I can't place it? I have a 2003 f250 crewcab 4x4 with 6.0 and 6inch lift with 37 inch tires....
View 3 RepliesI have had this truck for several years. I have only had a few issues. I've heard of engine noise issues but I have never had any until now. My 5.4 is making a knocking sound that just started. It goes away if I tap the accelerator. It has over 200,000 miles on it. I change the oil every 3000-4000 miles. No additives and always conventional 5-20. Is this a serious issue? I've seen people talk about using thicker oil but I'm very hesitant.
View 13 RepliesI 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.
View 14 RepliesI 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...

View 2 RepliesI got ready to change oil in our '09 5.4 SD and I ran across a passage in the owners manual that stated that if you use a non-Motorcraft oil filter it may cause engine knocking upon start up.
Our truck knocks for a second or so when it starts. Kinda' reminds me of the piston slap that occurred at start up with the old Ford 300 inline 6 cylinder engines of the past after they got some miles on them. Sounds somewhat similar. This engine has 35,000 actual miles so I wouldn't thing excessive wear would be the culprit.
I'm using a Bosch Premium oil filter now after having heard and read how they are superior in their filtering ability.
Just wondered if any of you guys have run into a similar situation and if the Motorcraft filter in fact makes a difference in reference to start up knock
2002 Excursion 4x4 7.3. I've read about this on here before but I've forgotten what the problem is. When the wheels are turned and the vehicle is going forward at some speed, there is a knocking sound, like a ba-doomp ba-doomp ba-doomp. Does it in both directions, sounds like its in the front hub area. I don't have the time to fix it myself, how much should I expect to pay a dealer and/or independent shop to do it?
View 2 RepliesI have a 2000 F250 5.4 that has a ticking/knocking noise. After about 30-60 seconds of first starting the truck in the morning, the ticking/knocking noise appears. It sounds like its coming through the exhaust system and seems to be louder under the front passenger side wheel well. When I rev the engine up, it seems to go away. Does this engine have a cam phaser? Could it be timing chain slap?
View 11 RepliesMy 2002 F250 is knocking loose the front end assembly--the gasket is worn out. So I was shopping around and was considering a beefed-up front end assembly.
View 3 RepliesWhile driving today, 2006 Ford F-250 5.4 L V8 138,000 miles , I experienced a problem. Started with the truck acting as if it was running rough, possibly missing. This was approx. 10 Minutes after starting. Checked the dash, no warning indicators and all gauges were normal. Approx. 4 more miles, the oil pressure alarm signals and I see the oil gauge has dropped to zero. I pull over, turn off and check the oil. Oil is clean and at a normal level. I restart the truck and the oil pressure goes back to normal.
Rev the truck up while sitting there and after a few seconds i hear a knocking noise in the engine and oil pressure drops again. Call the tow truck, driver used to be a mechanic . He asks me to start it again and the same thing happens. If you start it and let it idle oil pressure seems to go up to normal with no engine noise. Finally get to the mechanic and he calls me later saying the oil pump and screen may need to be replaced or the engine may need to be replaced.
Alright, I have a 2002 f350 7.3 4x4 ext cab xlt with 300k miles. Bought in may 2016 with 260k miles and towards November started running rough and felt like a loss of power. Had a no start but a new gray cps fixed that issue. Running fine. About a week later started it up and it had a rough idle, felt like not all cylinders/injectors were working. Was "knocking" and a loss of power. I was in the army at the time and stationed in Georgia, took it to a local diesel shop in Georgia and they confirmed my icp sensor was bad and injector #1 , #5 #7 were bad. Work was busy and money was scarce so I left it as it is and was saving up to buy the new parts. Then one day approx a week after the visit to the shop, I started the truck up and it ran fine. No misfire no knock no rough idle, drove fine for about a month.
In December, I was on vacation in florida to see my parents, drove the truck down, ran fine. While on vacation one day in a Walmart parking lot the truck didn't start up. Couldn't fix any issues then so towed the truck to my parents house. Did more troubleshoot, replaced fuel filter, cps, ipr valve, icp sensor, glow plugs, glow plug relay, ebpv pedestal was replaced with a ebpv delete pedestal. All parts bought oem and/or from riffraff diesel. Still would not start up. So then I bought a refurbished IDM from eBay, oem and then the truck finally started up one day but running rough again like it used to, then it wouldn't start again. So then, I replaced the PCM with a reflashed/refurbished one off eBay and boom truck started up, still running rough but now it starts up every time.
Now, took all eight injectors out and replaced all the o rings. Cleaned them up and put them back in, truck still running rough. Injectors didn't appear damaged nor the wiring harness so now I bought three reman injectors from riffraff. And replaced those three bad injectors. One of them is not spitting oil out the oil spout on the injector.
My dad has worked on freightliner semi trucks for years and is fairly knowledgeable when it comes to diesels. However he did something very amateurish the other day. So two injectors were installed while we were still waiting on the third in the mail. He wanted to see how the engine reacts when that one bad injector was not in play, but instead of unplugging the injector under the valve cover, he cut the wire outside the valve cover to the injector. He stated it's not a big deal and he can solder the wires back together. But once he cut the wire, the truck sounded a lot stronger, still rough idle but definitely stronger. Before, you would be pedal to the floor and the truck barely moves forward but now the truck will lunge forward. A big difference in power.
Now today, third injector came, swapped them out and fired up truck. We didn't solder the wire yet just quick connect, same you would use to connect wires for a car stereo. The new injector was not spitting oil out the oil spout. Even at high rev and truck warmed up. Truck still runs better with that one injector unplugged.
Tomorrow we will troubleshoot if somehow there's wires that grounding out or burnt out somewhere but as of right now everything seems to be in order, the uvch are tight, and no signs of anything burnt.
Triple checked everything, still getting fuel pressure, still getting oil pressure what gives? I also replaced the MAP sensor. Fuel pump is fine, fuel gets to fuel bowl. The next thing I'm thinking is maybe the hpop but we have oil pressure so idk..
Just became the proud owner of a used 2011 F-250 Supercab, 6.2L. Overall the truck is great but it does have a-few things that need fixing, the most annoying of which is a knocking sound from the rear passenger side cab corner. Sounds like the exhaust vibrating and smacking up against the floorboard but that's not it. Everything seems tight, even the front suspension.
The only thing I can see that may be the cause is the rear passenger cab mount seems worn. I can rotate the bottom rubber portion without too much effort and when I feel for the top rubber portion all I feel is the metal cup on the top, like the rubber has collapsed and the metal cup is sitting directly on the frame mount.
So... how many cab mounts there are for the Supercab? I think there are two on each side and two in the front. All of the information & videos I've seen describe the locations for the crew cab. Also, is it possible to replace the cab mounts and not have to mess with the ones in the front? I hear those are the real buggers.
2008 F-250 Lariat with EATC climate controls... My truck suffers from the knocking/buzzing/clicking that is apparently associated with faulty blend door actuators. I have been putting off getting them replaced because of the hefty price tag associated with tearing apart the dash and whatnot that is required to get to the lower actuator that sits right on the transmission tunnel. Anyhow, today was the first day I really needed A/C and it just wasn't cold. Cool yes, but not cold. Is there a way to determine if this is a function of the blend door(s) not doing their thing versus the system A/C needing a repair/recharge? I don't have access to any A/C equipment myself, how to determine if it's a blend door issue?
View 3 RepliesI 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).
One of the super coils busted while driving my 2002 F250 Super Duty. I drove it for less than 100 ft. before parking it. It made a rapid "check,check,check,check" sound, which I'm assuming was mainly the coil smacking against other parts while loose. It busted near the point where it screws into the motor. I felt like I lost some compression as it drove sluggishly once broken, although I only drove for a very short time. I also thought I may have smelt a slight burning scent, or maybe oil, but didn't smell anything once I got out of my truck. Any problems I should look forward to other than simply replacing this coil?
View 14 RepliesSo the other day i opened the door and heard a super loud clunk noise come from the door and when I turned the car on and pulled hte window down it wouldn't go down all the way, only about 75% of the way so I assumed like BMW cars the window motor died but oddly it continued to go up and down just now 100% down.
Then 3 days later when I came to drive the car again the window went down to the 75% mark and now its jammed there with no movement even if I tried to lift the window up myself. Usually a broken motor allows this to happen but since it isn't budging I am wondering if its an electrical issue with the power window button more than the motor?
I say this because when i try to lower the passenger window from the driver side it works than out of no where on the 3rd time it wont move at all than 5 minutes later it will move or if it doesn't move I just go and pull the window down from the passenger side then I come to the driver side and try it and it works again than it'll stop again. So maybe its the power window control buttons on the drivers side that's failing?
I have a 2016 F250 6.2 XLT CC 4X4 that is mostly stock, except I did put on 18x9 wheels and LT275/70/18 Cooper ST MAXX tires. I have noticed recently on hwy driving and even in town driving, that the passenger seat rattles/vibrates quite loudly. Obviously if there is someone setting in the seat, it is just fine.
Is this a common issue? Is there a quick fix (tightening a couple bolts or replacing a couple clips?) Or should I take this back to the dealer for warranty?
New floor mats. My truck is going to be 10yr old and has the original King Ranch floor mats. I want some heavy duty rubber ones that will fit around my manual transfer case lever. I ordered the Weathertech digital fit liners and I am not happy with them so they are headed back tomorrow. They have a heavy duty all weather mat but not sure how it will work with my shift lever on the floor. Husky liners/mats look nice and heavy duty but won't accommodate the floor lever.
