Ford Super Duty (1999-2016) :: 2006 5.4L - Knock Noise At Start Up?
Mar 28, 2016
I have a 06 F250 with a 5.4L truck has 50k on it. I have been reading many articles on the issues with can phaser/cam tensions/cam chain issues. I have noticed that when I start the truck a get a knocking noise that goes away with in 5 sec of the truck starting. I have been noticing lateley if I am sitting still at a light and go to give it gas for a short period I get a sound that sounds like a cam chain slap for a split second as the truck starts to move it goes away. I had a friend of mine stand outside the truck and put in gear and power brake it and as it decelerates you hear a quick cam chain slap. I use Catrol 5-20w standard oil and motor craft oil filter. I purchased the truck with #6k on it 3 years ago I have replaced the leaking exhaust manifold with Gibson stainless unit and have confirmed they are not leaking again. I have heard that the hydrolic cam tensioners sometimes get clogged and people have run a oil additive to clean out clog.

Ok I bought this truck with a bad engine 5.4 3v had rod knocking. I rebuilt engine got it all back together and in truck. I did replace cam phasers and solenoids. After driving 20 mins or so it would start the phaser knock at idle in gear so I put a oil pressure gauge on it and cold had 55 psi after running 10 mins or so had 15 psi at idle then would drop to abought 9 psi. I am thinking I got bad cam bearings or something for some reason don't know why. I did it but I took oil cap off where you pour in the oil. Had to force it off it was pulling that much vaccum ones cap was off oil pressure jumped up to 25 psi. What could be causing this.

2004 F-250 140k 4wd 6.0. Front end had noise, standard sway bar link knock. I disconnected the sway bar on the drivers side and drove it around. Smooth and noise free. Determined new links were needed, Installed new links and now even more noise. Disconnect them and no noise again. What am i missing? Bushings look good on the axle. Is the pressure from the sway bar putting strain on another wore part?

I have 05 F250 SD with 150k on it. The engine has the typical cam phaser knock, timing chain slap on start up and occasionally have a noisy lifter. As long as I use fresh 20-40 oil the engine symptoms are less and the engine runs strong. The motor also doesn't leak or burn oil and the plugs were change out about 20k ago.
The truck is still good and is prefect for my needs so to me it's seems worth fixing the needed repairs. What I would like to figure out how far should I take the motor... just have the chains, guides and phasers replaced or buy a rebuilt motor and swap it? I'm thinking just doing the phases and etc would be 1/2 the cost but may not last as long as rebuilt motor. But realistically I might only put 5-7k miles are year on it anyways.

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.

Code was showing for the knock and climbed under the truck and checked to see if it was plugged in grabbed the wire and to my surprise the wire kept coming and so did a piece of the knock sensor, is this going to affect my truck badly?? worst case?? 97 f250 4.6 standard

My V10 was knocking when accelerating under 2000 rpm; rain and moisture made the problem worse. I discovered that the 2-part wiper cowl under the windshield allowed water to leak into the engine compartment and onto the throttle body, which then dripped onto the left side of the engine. This caused the spark plugs to rust and the 3 back ignition coils (coil on plug) on the driver's side to crack and fail. This caused a horrible misfire/knock that was worst under 2000 rpm especially in high gear and when the environment was wet. I fixed the misfire and cowling leak. Has not returned. I caulked the cowl and changed all my spark plugs and ignition coils.

I have a "rattle/knock" that I think is coming from the doors on my 2000 F250 SD extended cab. The rattle is only there when the truck is going over bumps....especially closly spaced bumps. My buddy has the exact truck and it does not rattle.

2003 F-250 SD 4x4 w/5.4L engine and 4R100 trans (pic in sig) . Truck has 280K on it with about 40K on a partial rebuild on the top end.
Took the truck out offroading and got about 4" from the top of the 33" tire in water (not mud.. water) . Someone with 6' tractor tore through the puddle.....
Well the truck survived through it ... albeit dirty as all hell and developed some issues soon thereafter. Codes for misfires on cyl 1,3,6,7, general ignition coil, etc etc etc
Power washed the underbody , washed the mud off the engine bay (yeah... with water but given it was caked with mud and water to fill the plug wells... no additional harm) .
Replaced all 8 COP and 4 plugs ( easier ones to reach), oil change, oil filter, new paper cone filter. checked most all the harness connections and cleaned with alcohol also. Reset the PCM/ECU and drove the truck for about 100miles and finally just after putting a full tank of gas (92 Octane) I throw a P0325...
The engine runs very clean, no hesitation, smooth idle, smooth acceleration on both light and hard acceleration. Just the damn code. Is it the gas I just topped off? After 100+ miles with new COP and plugs it threw nothing until this and runs great. Dont hear any knock/ping/detonation by ear and feels silky smooth at idle.
I really dont want to have to tear the intake off to replace bank 1 knock...

I've been having sporadic starting issues with my truck since the fall. I had the spark plugs changed but that did not work. The hard starts usually occur when the engine is hot....after filling gas or just running into the grocery store. The engine seems to turn over slowly the first try and won't start. The second or third try the engine turns over normally and the truck usually starts.
I just got back from a 90 minute drive and shut off the truck for 5 minutes and now it won't even turn over. My thought is that it can't be the battery....its been charging for 90 minutes. Headlights are strong, wipers work fast, fan blows hard. That being said I think alternator or battery can be ruled out?
Where do I look next? Starter? Is there a starter solenoid that could be defective?

My 2006 6.0 shut off immediatEly after starting this morning and never started back up. I have a scan Guage 2 hooked up. I'm showing no ficm voltage and no sync even when cranking. I physically checked the ficm voltage with a dvm at the screw to the far right on the ficm, and I have 48 volts. Why do I have 48 volts at the ficm, but 0 volts showing on my scan guage? And no sync when cranking?

I just bought me a 2006 Ford F350 Lariat. A sticker in front of the radiator says says that my truck is equipped with remote start. How would I go about using it? I only have one fob. If it is in fact something that I can utilize I have seen guys on youtube program their fob to do it by clicking three times.

2002 5.4 super duty. My truck had started to ping, and knock worse over time. I did some research on this site, and I decided to remove my K&N air filter. Replace it with a traditional paper filter. Then I cleaned my mass air flow sensor. The results were great, no more knock and ping.I will check the MPG next to see if I get any improvements.

I went to start my 2006 F350 6.0 this morning. 20 degrees outside. It nearly turned over, then it appeared that the batteries would not support another start - a slowing of the pre-engine start revving....
So I let it sit a while, now it won't start at all. When I try to start it, the dashboard flashes, clicking sounds occur and even after pulling out the keys, the needles on the gauges shake for a few seconds.
Is this more a battery issue or an alternator issue?

So here's the deal, crank no start its getting fuel. Has base oil pressure and i put a ficm on that test good with a voltage meter key on engine off and cranking. I haven't hand any trouble finding info on this issue so. We can keep picking away. Just cant find anything about this.
A buddy of mine who has been trying to figure it out for me, Got it to start using a starting fluid. And it would run if someone was pushing the gas peddle but wouldn't idle. Or start without the starting fluid.

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??

i have a 2006 F250 XLT 5.4L 4x4 Crew Cab. after months of dealing with an ongoing power steering issue and replacing pumps left and right, i decided to replace the entire power steering system. Ordered Gearbox, Pump and Cooler from dealership. The install went fairly easy, and finished in 2 days.
The truck used to whine and grind as i would turn wheel any direction, driving or in park and the wheel used to pull , like jerk a bit when i would go like in a u-turn.
Not anymore, all those issues are gone. Steers straight , no whining , wheel doesn't pull anymore and all seems fine, EXCEPT when i take a turn , for example onto a driveway where its a bit of an incline. Then, i hear some grinding noise and a bit of vibration in my wheel. I think it comes from gearbox or pump.
Im scared not to drive it too much as all is new components and don't want to ruin all over again.

My 2006 F350 is giving me grey hairs. I'm trying to figure out what's going on with it. I have been getting an occasional (more often than not) grinding noise from what seems to be the front of my truck. It will do it from a stop, under light, moderate, or heavy acceleration. Doesn't matter. If I let off the throttle momentarily it will stop until it shifts and will grind again through all shift points it seems.
Logic says it's got to be the wheel bearings or locking hubs. I recently did both on both sides to no relief. Because this is an 06 it had a different hub set up then the previous years which I've read a lot of info about (needle bearings). It doesn't make a lick of difference if hubs are locked or on auto. If in 4x4 (ESOF) or 2wd.
As mentioned I replaced both wheel bearings with FORD parts and both locking hubs From FORD as well. (Small fortune). Axle u joints seemed tight. Greased me up but no play.
