Ford Super Duty (1999-2016) :: 2006 F250 V8 - Knocking Noise In Engine And Oil Pressure Drops
Jan 13, 2015
While 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.

I have a 2001 Ford F250 V10 with about 70,000 miles on it and now the gauge indicates low pressure when my warmed up truck idles around 1000 RPM.
I went off road the other day into some mud and since then I have had my oil pressure gauge reporting low at idle and normal when moving.
I was a quart and 1/2 low on oil which I filled and the next day I changed the oil. I then had taken it Ford shop who replaced the oil sensor and said all fixed. It wasn't and I took it back in ... now the mechanic indicated it is probably the crankshaft bearing based on his experience and I should replace the engine.
This seems drastic? Wouldnt' the next step to go check/replace the oil pump?

I have an 05 F250 Super Duty 6.0 V8 Turbo Diesel. This is my first diesel so don't know my way around it too much yet. I just don't know what could cause this problem. It sounds like a faulty sensor to me. But no engine light has come on. My oil pressure drops down to in the red zone when I brake while driving, then once I return to driving again it returns to the normal pressure. It's almost as if it has something to do with the tilt of the vehicle.

I 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?

I have a 2013 F550, v10. At idle, the oil pressure gauge drops and the red oil light comes on. If I hit the gas, the gauge pops back up. I swapped out the oil pressure switch. That didn't fix the problem.
I thought maybe the gauge was faulty, so I bought a 2 inch mechanical oil pressure gauge and hooked that up, leaving the factory gauge disconnected.
I watched the oil pressure start around 50 psi cold, and it slowly fell to 10-15 psi as it warmed up. The truck has 65k miles on it. There is no knocking, no ticking, no loss of performance.
I cannot imagine that at 65k miles, that it would be a worn engine. Right??

Ok I rebuilt the engine in my f250 5.4 3v. Timing set cam phasers and oil control valves are new. The problem I'm having that just started after 5k miles on a new engine is all of a sudden i will start getting misfires 1st time it happened said #6 i changed coil same problem came back this time said multiple misfires now I'm just getting #4. When the misfires happen if i hold throttle where it is it will misfire as long as i hold it there if I let off gas then apply right back misfires stop for several miles then will happen again. I have changed fuel pump and fuel pump driver module same problem exist.

We have replaced 4 fuel pumps on a row.
Voltage is good...even ran a fresh circuit.
Ran new supply lines
But, can't seem to understand the continued drop in pressure. It usually takes about a day of driving to crater after a new pump/filter is installed.
It never dies, just loses power and drops the truck to an idle. Funny thing...if I shut the truck off and turn it right back on...full power for a short period!
The truck is used on a ranch that has plenty of rough roads...thought inertia switch maybe but i believe that would stop fuel completely right?
I am totally stumped and so is the mechanic.

Does it need a diesel fuel injector?

I have a 2006 f-250 powerstroke with 97000 on it egr delete exhaust and a h and s xrt pro on it. The pickup will always start when the engine and oil is cool, but once i run it for a while it and the oil gets warm it wont start back up again. I then have to leave it sit for a while and it will start. The engine just cranks but does not fire. I have replaced the dummy plugs on both sides and all the injector o rings on the passenger side. Some mechanic friends of min have had same problemed 6.0 liters and replaced these and it has fixed the problems I do not think it my high pressure pump.

My tachometer hangs out around the 600 RPM spot when I first start my truck, but lately it will end up dropping to zero when idling, and then bounce up to about the 200 RPM point when accelerating. Its not the Cam Positioning Sensor (I had that happen with my 99 7.3) and this truck runs great. I am thinking it could be at the tach.
Question is: Where does the Tachometer signal generate and does the PCM do anything with it before it sends the signal to the Tachometer? The reason for focusing on the Tach is since the engine runs and idles fine, then that tells me the PCM is receiving the correct signal from the engine and making changes accordingly. I read about a 5.4 gas engine with rain issues, but the only issues going on here is extreme cold (tonight, -15). I keep the truck garaged and when I go out, it is for purpose and then return home to a heated garage.

I have a 2006 f250 lariat 192k no mods except k&n filter everything is stock. I have 2" pro comp level kit and a scan gauge 2 nothing fancy! Well the other day I noticed my truck was chirping like a Chirp chirp chirp...... Chirp chirp...... Chirp chirp chirp! It goes up and down with the rpm's but it's comes on and off only when the engine is up to running temps the belt does squeak during warm up but I don't think that's it, it's coming from the back of the engine I'm sure of it because I used a paper towel tube and listed right in the turbo hpop area on top of the engine but it's too hard to tell I can't find exactly where it's coming from, some people I've had listen think it's a belt or pulley or tensioner! But I'm not sure if it is because I've sprayed water, and wd40 on the belt and pulleys with no change!!! I'm afraid it's a lifter or something inside the engine yet it's too loud and pronounced to sound like it's coming from the inside! I'm just lost!

I have an 06 f250 that is making a growling noise that is speed sensitive and sounds like it might be coming from the front. I thought it was tire noise from my old worn out tires but with new tires it still maks noise, but tires have pretty rough tread. How can I tell if it could be a wheel bearing? It seems like the noise quiets down a little on right turns. It is kind of a growling humming noise that changes with speed.

I replaced the head gaskets on a 2006 F250 6.0 Diesel, put it all back together and started it up. It ran great for a lil bit, then it started cutting out. It did this for about an hour then I killed it and it took a little bit to restart it, spinning over and over to get it to run, this took place several times. The engine died and now it will not start. I keep getting codes P2284 and P2290. What could be causing this problem??

My dad has a 2006 F-250 5.4 3v that spun a rod bearing at 107,383 miles. He's never been thrilled with the performance of it (told him he should have gotten the 6.0 when he bought the truck new, but why listen to a 15 yr old ). We've been throwing around a couple different ideas for engine swaps since the 5.4 is dead. We scored a 5.4 2V Lightning engine, but after trying to figure out transmission controllers or if we'd be able to tune the stock PCM for the 2v, we've put the project on hold.
Recently, I've been trying to convince him to do a diesel swap over the L-motor. I have a friend selling a cheap 99 7.3 with trans, PCM, harness, intercooler, piping and other misc stuff. Would that harness generally be plug and play with the body of the 06? Would it be more worthwhile to try to find a 6.0 from 05-07 and swap everything over?
I've also been considering a Cummins swap, although I haven't gone much past looking at complete engines on eBay and Craigslist. Would this be the better route, and just get a standalone controller for the 5R110?
So I'm looking for other's opinions. Should we go 7.3, 6.0 or Cummins? Should we stick with gas over diesel? Try to make the Lightning motor work? Or just go back with a stock 5.4 3V? I should say, he won't sell the truck for whatever reason, so he's not worried about resale or anything. We're in Michigan, so we don't have to worry about emissions. And we're fairly mechanically inclined, so I'm not too worried about doing the swaps, however my knowledge on diesels is limited.

I have an 06 f250 6.0 when I'm driving and let off the throttle and coast I hear a rattling sound like a spray paint can being shaked sounds like its coming from engine compartment.

My 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.

I drive a 2000 F250 5.4L. Currently has about 168,000 miles on it. I changed the oil the other day and cleaned the air filter. I used what I usually use on the oil change which has never been a problem. But this is first time to clean the K&N filter. A day or so later my engine is making a loud air rushing noise. Under throttle the engine compartment sounds like a wind tunnel. At 3500ish rpms it makes a harsh whistle noise. The air rushing noise doesn't go away once its warmed up or after the engine has been cool. Noise didn't go away with the filter being taken off either.
Could all of this be caused by cleaning and not using k&n air filter oil (but rather WD40 upon Dad's suggestion)? Or is there something else going on?

I have a 2004 ford f250 5.4 and ithe makes a Humming noise only at idle. I have checked the fan clutch. it seems to be good and does not spin freely. I was thinking maybe idle air control valve but the truck idles like normal and does not stall. the sound does go away when squeezing the air hose doing today the IAC but comes back as soon as you let off. can it still be the idle air control valve if idles fine and doesn't stall?

I have a few F-250's that have been having steering problems. and they all have the same symptoms.
When taking a long slow curve, the steering wheel will jump back like 6 inches, as if the pressure is going out. like say you had the vehicle turned to about 10 oclock, the wheel would go back and forth between 10 and 11. However, you do not loose much of your turning. It just has more pressure against your hand as if the power steering goes out.
You can also do it a standing stop. Only when you turn your wheel like say to 9, you can just use a finger to hold it there and it will bounce up and down? I have asked the local Dealership, and their answer was "there is something wrong with the power steering." couldn't get much more vague than that I guess.
I have looked for leaks, none. Checked struts, not bent. Checked tires, all brand new and balanced. Checked steering wheel mounts, all good to go... ???? Just lost...

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.
