Ford F-150 (2004-2008) :: 2005 - New Engine / Knocking Won't Go Away
Feb 5, 2012
I have an 05 f150 5.4 v8 super crew cab and I bought it for 3000 because of a cracked block. I bought a re-manufactured engine and installed it and now i have a knocking that wont go away. After I started it up it sounded beautiful for about 10 minutes and then i had a knocking start up. I have put about 30 miles on the new engine and still have the knocking. I let it sit over night and I started it up and there was no knocking so i drove about 3 miles to the gas station and by the time I got there the knocking was back. it runs fine no other issues but why do I have this knocking with a new engine.

Having issue with his truck. He bought it 3 months ago and has no history. 166k. You now know as much as I do about the truck! He knows little about automobiles so fact finding has been difficult. I have done all my own work on countless US and foreign automobiles over the last 30 years and never take my vehicles anywhere. I will try to post as much detailed info as I can. I have read tons of posts now on various forums so I am up to speed on VCT and phasers.
This one seems similar, but not exactly the same symptoms which is why I am here. I have already pulled the VCTs and found the passenger side missing the top screen. I swapped them from side to side which made no difference. I checked ohms and they were at 15 which is normal from what I read. They were very clean and moved easily when I took them out so they were not gunked up so I don't think that's the problem. It idles very smoothly and isn't rough at all.
I have posted a video of the knocking/dieseling noise (link below) coming from the passenger side. The knocking starts as soon as the truck is started hot or cold (outside temps right now 70F-90F Houston). I can make the knock disappear by gently depressing the gas pedal going from idle of about 650/700 to maybe 750/800 and it will go away completely as long as I keep it gently depressed. As soon as I lift up it returns.
If I rev it up to 2000-3000 rpm it does not knock, however, as soon as I lift off quickly, it seems to knock at a high speed, hangs for a second and then knocks all the way back to idle. However, if I rev up and then lift off very slowly, it will not knock. I have tried to locate the exact location of the knock, but doesn't exactly seem right at the phaser, but actually back around the 2nd and 3rd spark plug area, but I can't tell exactly. I've had a couple people tell me the same when I asked them to tell me where its coming from. The noise is bouncing around in there so difficult to pinpoint exact area.

I wanted to get some second opinions on what this could be so I know where to go next.

I have a 2004 F150 Lariat Supercrew 4x4 . I got a new transmission put in and a Oil change shortly after. A few weeks later I got a knocking noise. No check engine light, starts up great, No real notable problems just the noise. At Idle no noise just the usual cam phaser ticking, but once the engine is warmed up at about 1100 RPM it starts knocking like a . I took it to a few different shops one was sure it was the timing area so they replaced the timing chain, tensioner, pully. ect. Took it to a ford dealer where he didn't really look at it just said you need a new engine.
I went to another ford dealer where they said rod knock or stuck lifter but if that were the case shouldn't it knock constantly? another shop said VCT soleinods, Spark plugs. another said it could be the flex plate! I'm aware of the cam phaser diesel ticking noise they notoriously have but thats not it. I've parked it for a few years to be safe but started it weekly. I didn't intend on having it sit for so long but due to work situations and what not it has sat but now I'm on a mission to make it my daily driver again. I'm no mechanic but I'm not totally green to vehicle mechanics so ill be inspecting what i can within my limits.

I have a 2004 F150 with a 5.4L with a little over 100,000 miles. And the engine knocks like it about 1 1/2 quarts low on oil! I'm not a mechanic by any means, but I'd like to know how to get this fixed. I've actually had 2 different people ask how I got a diesel engine in a 1/2 ton truck!

I have an 04 F150 Lariat with the 5.4. I get alot of noise out of the top of the motor. I hear lots of stories of sludge issues, is that the problem or do I need to have the motor gone through? the knock is not horrible but when the motor is warm the noise is pretty apparent!

I have a 2007 F-150 4x4 5.4L. I recently had a problem with my engine. It had the knocking noise thats known for the 5.4. My issue is i replaced the engine (it had 275,000 miles and was a work truck before i bought it) As well as all the timing components including the hydraulic tensioners, new phasers, new guides, new solenoid, and a new camshaft positioning sensor and it still isnt fixed.

Driving home the other day I noticed some vibrations up front. Reminded me of out of balance wheels. Then the check engine light started blinking. Then it was on steady, then blink, then steady... Took it easy the rest of the way home. Code reader said P0138 Oxygen sensor circuit high voltage bank 1 sensor 2, and P0304 Cylinder 4 misfire detected. At home is where I saw the engine shaking and extra noise from it (visions of piston rod slapping around in there). Removed plugs (original? tough to get out!), compression tested all 4 cylinders (130 to 140), new spark plugs (had they been in there for 196K miles?). Start engine and same, shake shake with some extra noises that weren't there before (car just sitting in driveway).

ford f 150 2005, engine wont crank over. Tried all these remedies but none of them work. [URL] .....
Here was the scenario: someone drove my truck in 4 low for a very long time.3 hrs doing over 80 km/h) When i drove the truck i could get it out of 4 low it is still in 4 low. But then the truck died on me.
The alternator pulley went on it. replaced the alternator then proceeded with the remedies from the link above.

I drive a 2005 F-150 XLT with a 5.4L engine in it. This problem only happens after I have been running the truck on a small trip (15-20 min), stop to get something, and then 5 min later start the truck up, and this is the feedback I get.
-Sometimes it barely cranks, idles for a second and then cuts back off.
OR
-Takes much longer than usual to crank and get's going fine.
This is the only time it happens, upon restart after driving for a short period.

My dad is looking at a 2005 F150 2wd with the 4.6L V8 that a friend of his has. Its a 2wd XL, but has the cloth seats, the interior and body are excellent conditions. Its high mileage however, (210K), but the engine sounds good, but it has a miss and the check engine light is on. He took it about 6 months ago and had the oil changed, new belts and spark plugs, drove it very little and its been setting for sale for about 3 months.
When dad started it this evening, the engine was missing and the CEL light is on. His friend suggested he drive the truck for as long as he likes, (which he did today and he does like it) but I advised my dad to take it to a mechanic and have it checked out first, maybe even the dealer to have it checked out to be safe.... which he did today. He took it to a local Ford dealer today to get them to check it out they stated that it was a coil pack that is bad on the #2 cylinder.
They (dealer) also told him a bunch of other things that was "wrong" with it, but I think a lot of it was lies just to get him to get it fixed there and make money off of him. They said it needed an intake gasket (said it was leaking a little bit), they also said, battery and cables need to be cleaned, tranny service, coolant flush, etc, etc, etc.
Once outside the guy (tech) was bringing the truck out and my dad asked him the about that intake gasket and he acted like as if the dealer makes them act like things are a big deal, or saying they may not always need what they say. He told dad alot of those 4.6L's did that and it was really nothing to be concerned about, but I don't know.
I have a 95 Town Car with the 4.6L and am familiar with these cars, but I guess the 4.6L in these F150s are different beasts. I do know the plastic intakes on the 96+ models were issues.

I just purchased my first F150, 4.6L V8, 55,600 Miles. It intermittently has a rough idle and only seems to be when the engine is hot. I've had engine and tranny mechanics look it. The spark plugs have been inspected and are within an acceptable range. The throttle body has been cleaned. There are no trouble codes of any kind. What I can check next?

I have a 2005 f-150 with the 5.4 engine. Bought it new and now it has 107,000 miles on it. Recently,it would have a shudder at 65 or 75 mph then the passing gear would kick on and it worked perfectly. The warning check engine light came on,then,when it acted up it would flash intermittently. Took it in to the dealership and put it on the diagnosis machine. Said cylinders 2,3, and seven were not steady etc?? So,after he took it out and drove it he said those particular cylinder walls were scored. I put in a K-N air filter at about 50,000 miles,and he said that they do not seal properly and dust got by the filter into the intake and got into the engine and did this damage. One think he found was a bad coil on one cylinder and replaced it. And just as he said,when I got on the road home I romped on it and it cut out and the intermittent signal showed again! He said that that would happen and it did.

I have a 2005 FX4 with a 5.4L. I have noticed in the past 3 months that when I mash the go pedal hard the engine misses and there is a popping sound. My gas mileage has gone down 2-3 MPG.

I have a 2005 f150 with 96,000 miles. Long story short, last August I was headed to the mountains going up a steep long hill and the engine light come on. once i was over the pass the light went off. During my 4 wheelin' trip it never came back on until I was headed home and going over another pass and then it stayed on for a couple of days. I had it checked and it was a cylinder 5 misfire. I did some research and found that replacing the coil cover might fix the problem and if not the spark plugs would need to be changed.
I changed the coil cover, problems solved... until I headed to the mountains. light came on and then eventually went off later that day. I didnt think much of it. then a few months later i was headed to the mountains again and the light came on in the same place on the steep incline hill. I. took it back to the shop, same reading. I decided it was time to replace the spark plugs anyways so I would invest. I have new plugs and everything is good however, I had no plans to go to the mountains in the near future. Now, a few months later I headed to the mountains and crossed my fingers it would not come on but it did.
I've done the research again and it seemed like the coil cover and spark plugs are usually the cause of the problem...however I have changed mine. The light is now off again. I don't understand what is triggering the problem and what is really happening and if it is safe to keep taking to the mountains with this happening. I did notice that everything was fine at 60MPH but once i hit the hill and steeped on the gas to go 65 and hit 4-5RMP that is when the check engine light came on...

Had the check engine light in the 2005 F150 (90,000 miles) come on. Got the code checked and its P0420. I know that has to do with the cat threshold levels etc. so I believe I am looking to replace the o2 sensor, if I am not mistaken.
How hard of a job is this? Ive done a decent amount of engine work and worked in a shop in high school. Just looking to see if that is the right thing to try first, replacing the sensor, before replacing the cat.
Also I know its the right bank, but if I am not mistaken there is a before and after the cat o2 sensor, which do i replace? Both?

My 2005 STX 4.6 fuel pump crashed a couple of months ago. A couple of days after having it replaced I started having hard/rough starting problems accompanied by a 0300 and 0301 code. I reset the codes several times and they only come back during the 3rd or 4th hard start, never while driving. The hard starts occur after the engine is shut off for more than a few minutes after driving. I have replaced the plugs, #1 COP, remaining COP boots, Cam Pos Sensor, Fuel pump drive module and had and FI. Also had the fuel pump replaced again on warranty thinking maybe a bad check valve. Again...it worked perfectly for a day and now I'm back to square one. Haven't gotten any codes YET but its only been a day. Bad injector? EGR?

I have an 05 F-150 Lariat 5.4 and it has been going haywire today. While driving if I hit a hard bump the power will cut off (radio, a/c) and even sometimes the truck. Check engine light came on and I pulled codes P2160 & P0506. Also, when it completely cuts off and I start it back up it says "engine in failsafe mode".

In this video I go over in detail the procedure to swap out the Cam Phaser to get rid of that annoying knocking noise at idle! It is easier than you think. The procedure is the same for all 4.6l and 5.4l 3valve engines.
