Ford 4.6L & 5.4L 3v Engines: Camshaft Phaser Failure Inspection

[@newtonslogic]

Can you please do a complete engine rebuild video? You're the only mechanic on KZbin that I trust and I'd like to see you do a complete tear down and rebuild.

[@michaeltorres9575]

THX FOR SHARING YOUR KNOWLEGE BY TIPS ON THINS TO PAY CLOSE ATTENTION ON EVERY ASPECTS.

[@jameslehman7015]

Oh my goodness! You saved me so much grief and money. I lost timing on my 05 f150 while removing the right head with broken exhaust studs. I set up timing like i was suppose to in your other videos. Right cam phaser also had an L mark? I set timing to that. Truck was way off. Now i see to use the other mark for the right side! I was 180 deg off. Was at my end. Had scheduled to take it to the dealership. Now i can fix my problem. Thanks!

[@SangheiliSpecOp]

You've been posting a lot of camshaft phaser and solenoid stuff lately.... XD but if it wasn't for you my car wouldn't be running perfectly right now so THANK YOU!!!

[@stevefowler1787]

Great vid...greatly appreciated...I understood the concept behind the phaser but have never seen someone explain what to physically look for maintenance.

[@jasonbice1103]

Guys make sure you get oem ford parts, I put two sets of Dorman on before I learned. Its defiantly worth the extra nickel.

[@lexusry]

THIS IS MUCH BETTER THAN READING MAGAZINE OR BOOKS. THIS GUY IS GREAT

[@hebertogsx]

Great job!! You really are making the difference for us DIYs, infinite thanks for sharing your knowledge!

[@ChipGarlock]

I wish someone had told me to check the oil before diagnosing cam phaser problems. Once The crank case was full of good motor oil, the cam phasers started working perfectly. I didnt realize that the engine was low on oil and needed to be changed also. This caused the cam phasers to knock and rattle and I was about to spend $900 and my next couple weekends to change the timing set.

[@michaelspeakman8924]

I seen where they make kits to block those. From advancing. And I have seen them fixed the top of heads with a line boring machine. And the only thing you have to do is replace the bearings for just like connecting rod bearings. They're just a lot smaller

[@MiguelMartinez-np8uo]

This video is great , thank you for sharing your knowledge and the the tips on here .

[@kenni411]

your videos are awesome dude ! i really appreciate your channel very informative !

[@albertortiz5254]

Can you please do more videos of the 4.6L 2 valve engines ? All i've been seeing are the 5.4L 3 valve engines with the phasers videos! 😭

[@rogerharrelson1565]

Thanks. Changed out passenger side still making noise at hot idle. Going to change the driver's side

[@SangheiliSpecOp]

5 years later, I'm back here ma man. I still have the same 2008 GT. Tried to go out to McDonald's yesterday morning and the engine cold started just fine, then random started running super rough as I was exited my drive way and engaging my clutch at low rpm. My engine has 210k miles and I have retimed it twice, replacing chains, sprockets, phasers, vct solenoids, but I have never replaced all lash adjusters or followers (only a couple that have failed followers here and there) so I wonder if thats it. Timing chains and guides look fine from looking down from the top of the engine (valve covers removed). I hope I didn't spin a bearing or have a follower bend a valve or something crazy. Or maybe my car just had an electrical issue and went into limp mode. Not sure but I'm still doing some diagnostic tests. I'm about to use the follower tool to pull out all 24 followers and inspect them. I'll also check the lash adjusters. If its bottom end stuff, I might have to take it to a mechanic

[@gyulaasztalos7470]

Thanks for the video I have a question is there any oil supposed to come out of the back of the cam phaser only at one point? Thanks again

[@ramonacevedobravo4398]

You said can be used left or right… so those 3 tone rings for timing mark doesn’t matter for the right side has 2 you said can be used for the other side?????

[@utahbones3094]

I'm throwing in the towel on this motor, new oil pump,timing set,phasers,VCT solenoids, it was quiet for a month then started to gradually rattle on start up and now when it gets warm it retards itself and dies at idle. My first ford and it's a junker.

[@ramonacevedobravo4398]

I never have the facer in my hands to see if the tone rings rotate if can be used on the right hand side the has 2 tone rings!!!

[@rogerharrelson1565]

Changed out passenger side cam phaser on my 2009 still making same noise. And changed cvt

[@dr.marka.f.knightm.d.7699]

Brian, what would cause the return spring to break? I just had this happen to me on the drivers bank.

[@chrisb4013]

Is this the same cam phaser design for the new ecoboost 3.5 and 2.7's? I wonder if we will see the same issues with the newer trucks

[@clep2009]

Awesome video. I have learn so much with you that I really, really thank you from the bottom of my heart. I know it has been 7 years ago when you posted this video so I dont have high hopes of getting and answer but maybe I will be lucky. My 2004 Ford 150 has started developed a sound like a little piece of metal being tossed around at the passenger valve cover, right where the phaser is or the upper part of the timing chain cover. It is not a regular noise but an erratic one exactly as I said, like a piece of metal being tossed around at random. It started after I left my truck parked in my driveway for 4 days. It was a cold day in NY when I started the engine and I felt a weird noise. After that, this noise appeared. It will be present with the engine cold or hot. When I saw this video I though that maybe one of those roll pins came out and is being tossed around. Could this be the cause of the noise in my truck? By the way, much before that I plugged a scanner and I saw the passenger bank was retarded 20 degrees at iddle while the other was at zero. I have a pending code P0010.

[@tekdiver6245]

Thanks Brian ... Awesome series of videos. I need HELP with 2005 F150 5.5L 3V Phasor. Watched all your videos and am changing all of the timing components. I ordered two genuine Ford timing parts and phasers. One arrived OK and the second arrived in three pieces!!! Reluctor, spring and sprocket assembly. Snow is on its way and I am screwed unless I can put this second phaser back together ASAP. I have positioned the spring correctly but am not sure where to position the reluctor base into the square spring end and how many turns to rotate it so the reluctor ends up in the correct position. Cant afford to get this wrong and put the engine back together.

[@thatmexicanmechanic8261]

Is there a way this can delete or a some kit for “fixed position”??

[@carrieeyre6376]

Getting a hard raddle at startup, do the phasers rattle hard or soft tick when they go bad?

[@SangheiliSpecOp]

That is probably the timing chain and their guides and tensioners if you hear a rattle for 3 seconds or less. They quiet down when the oil starts flowing. My Mustang does it with no problems. Eventually you may need to replace the timing chain guide and tensioners, Ford made them out of plastic for my Mustang for some reason. They will get worn out faster if you run your car low on oil for a long while.

[@hawaiianf1504]

Really Awesome Video. couple questions - If someone did take all the screws off the reluctor ring, (1) is it hard to reset the phaser spring back in the housing? (2) Is there a special procedure to align the marks? lastly, if we look at the tone ring and gear sprocket locations - (3) how much off is allowed to "perfectly" aligning up the gear tooth to tone ring tab? Is there allowance at all when matching up the center of the gear tooth to center of the tone ring tab? The reason I ask that and I know that is a used phaser but when I look at the tab on the tone ring in the video, it didn't seem to align exactly with the center of the gear to the center of the tone rings tab.

[@eddiecruz3679]

Can u put in some phaser lock out on a bad phaser??

[@dannydonovan9348]

Will the chatter happen because of weak springs? All else is good

[@WEBBBASSIST9]

Completed my timing job by following your videos. First problem I had was my truck would shut off at stops. And then I developed a knock. I removed the valve cover and Phaser on that side and found my new oem Phaser broke. I reinstalled one of my ld phasers in and the knock came back while doing the idle relearn. Any ideas.

[@amtpdb1]

I replaced a cam on my 5.4l. When I put in the new bolt and tightened it the last 90 degrees the cam rotated slightly. So I had to tighten a little more. When I did, it gave way slightly feeling like the bolt was failing. The engine runs fine and is quiet. Have you ever felt this when changing this bolt? Thanks for the videos.

[@TequillanSunrise]

Some people hate on Ford, but I'm not phased !

[@MrErikw26]

thanks in advance, looking forward to your next video.

[@FINELINEVAN]

I was told by dealer when I bought my 09 Mustang GT to use 5-30 synh oil its better for cam phasers and thus engine then the 5-20 you agree?

[@MOAArtstore]

Do you happen to have specs on type of steel used and dimensions of the fins? It wouldn't be hard at all to make new fins if that is the primary internal failure point. Unless, they take out the groove they ride in. Then, it might not be a viable option.

[@Sandbag1300]

Thank you for that excellent explanation. Thumbs up!

[@israelarreola7295]

great videos! I have a 2008 Ford Expedition. I have changed the camp phasers, timing belts, oil pump, vct, tensioners and changed the oil. Runs good but knocking noise has not gone away. it's louder when it's on low idle. Any idea what else I can do to fix it?

[@badrfisal]

hello thank you for the video. I replaced my cam phasers on my 5.4 2008 expedition then code P0340 and P0345 has appeared but the vehicle running fine I had the code for 3 months

[@FordTechMakuloco]

+Badr Fisal VCT solenoids are next. If the codes appeared right after then the timing is off.

[@badrfisal]

I have replaced the vct solenoids. The car idling good do you think it's timing problem?

[@technojesusentertainment]

+FordTechMakuloco hi i have a question i have a 2016 mustang gt do you think putting aftermarket oil separator should be done?

[@muzikmaniak09]

I've heard of people "blocking out" the cam phasers. It's suppose to keep them at base timing and give these engine more longevity and of course horsepower would suffer. It requires programming of course. How do you feel about this procedure?

[@MyJesus99]

Im having issues with the phasers a mechanic recomended me this procedure of blocking , did you did something similar, or do you have more info on this ?

[@andresrazo7317]

That’s causes Ruff idle and makes the vehicle stall and shut off right I have this issue on my mustang if I take a little longer can it damage my motor

[@juliemahanay3300]

Could a persistent p0340 & p0344 code signal an issue with the phaser? Alternator & both sensors replaced at dealer and they checked all wiring and cannot figure out why it's still throwing these codes.

[@cindycox9283]

I replaced the timing chains, phasers, guides and crank gear on a 2007 ford expedition. The job was quite simple thanks to your video. after installation was complete the truck cranks up fine idles fine and drives with no issues however it runs for about 30 min then starts running rough and dies. it will not crank up after that. it turns over and acts like it is out of time. i can let it sit for a couple of hours and then it will crank up and run fine again. the is no check engine light or codes. I have changed the cam position senors out, this has me and my mechanic stump. just wondering if anyone has had this issue.

[@cindycox9283]

thanks

[@SolRay412]

Awesome video Brian, Thank you. I have followed your videos in the past wile doing the cam phaser/timing R&R and also spark plug R&R. All took some time but went very well with the help of your instructions. Very much appreciated! I wonder if you could tell me if you see phaser failure happen often with lack of oil pressure. My 05 F150 has recently died wile in motion and wile it will start (occasionally) it runs very rough for seconds then dies. After further inspection it seems I may have had an oil leak at the front cover where meets the oil pan. Is it possible that lack of oil caused the phaser to fail, throw off timing and causing the truck to, now, not start/run? or should I be considering other avenues? Thanks in advance!

[@THETOPGLOCK]

Brian, is there a way to pull off and put on the brake booster vacuum tube that connects to the back of the intake manifold without pulling the intake? This tube made it a real PITA pulling the driver side VC. With this tube in the way I found it easier to pull the passenger side VC without discharging the AC. 2007 F150 5.4

[@ozzstars_cars]

Hey Brian do you know if Ford has improved the quality or design of this part?

[@CarmineRC]

I'd like to know as well. Is there an improved aftermarket piece available yet??

[@jacobr2228]

If the phasers fail will it cause a bank to drop out on relative compression? And or /cause a crank no start condition?

[@bayberautosales1829]

hello i have 2007 for mustang 4.6 did almost everything to it. my phasers are after market auto zone. i'm still getting timing codes p0022 and 12 timing retarded. only when warmed up and under load. soon and i give it little gas engine feels like it will fall apart. Any tips thanks either way. and thanks for the great videos.

[@daltonolexo2798]

My 07 5.4 triton 5.4 3V XLT won’t go over 3000RPM n barley over 15mph what could that be?

[@austincarpenter1836]

In my truck I have a timing gauge. My timing bounces around all over the place, going anywhere from +3 to +18 at idle, I'm assuming this isn't normal. Is this a definite sign of the phasers about to go out? VCT solenoids recently failed on both sides and were replaced, this timing issue has been happening for months. Thanks for the input

[@صيانةالسياراتعلموخبرة]

what is vvt base timing?

[@mrbill9454]

Is the phaser in the link still the latest version? Just wanna make sure I'm buying the latest and greatest.

[@MustafaExplore]

Thank you so much for the informative video, I have 2012 ford expedition 5.4L, mileage is 200KM. It has the P0024 code with "check engine on" for over 2 years now, I have changed the The Oil Control Valve (OCV) to the bank 2, but it did not fix the P0024 code. do you think using the "Cam Phaser Lockout" can fix the problem. note1: there is no knocking noise sound, the sound of the engine is good. note 2: mileage per hour is always around 12mpg. note 3: I am using 5W30 full synthetic engine oil. Thank you.

[@mercedesbenz4855]

If the cam phaser is bad can it throw off the timing?

[@andyk193]

if you use the lockouts does your truck have to be reprogramed? will this bypass the vct soid. in the valve sovers?

[@garyclark8891]

If the cam phasers go out will the engine light come on ?

[@AlejandroMartinez-re8mh]

How change t camshaft salonoid on a expedition 2008 do you have a video??

[@anthonyaubrey9186]

I've changed both phasers, both chains, both tensioners, oil pump and both VCT solenoids on my 06 f150 5.4. My truck will start and run fine but as soon as I accelerate, my truck will die at idle. Any idea what's causing this?

[@MrSeductive1234]

so i just bought a set of camshaft phasers i talked to a mechanic and he stated that there was a new style of phasers with a new design that make them not be able to be noisy. like the oem ones that end up clicking any insight on or what they did to fix them.

[@FordTechMakuloco]

+MrSeductive1234 I have no idea what he is talking about unless he can give me specifics.....

[@adamjohnston9768]

Fordtech, i have watched most of your cam phaser vids. Thanks. I had my engine rebuilt at 145k. After market parts but melling pump. Ran poor when i got it back, replaced vct solenoids w oem ford and it has run well for about 20k miles. I am at 195k now, i put new oem chain guides and tensioners...still stalls at lights. What are your thoughts on phaser lock out? I am not convinced ford phasers will solve this now terribly discouraging motor issue.

[@tylerlong4696]

Can a bad cam phaser cause a misfire I’m the 5.4 triton ? I just had my could m plugs replaced a few months back. Now I have another misfire

[@pyracing]

I haven't torn my engine apart yet, but I have replaced both camshaft sensors. It runs GREAT for about half an hour then it starts idling rough again. Sensor one ,(left one) had oill on it, sensor 2 (right one) was clean. Blown Gasket? It was burning rubber when I first replaced the sensors. Now its losing power. I also have a Performance chip installed in it, I just installed it to see if it would help with the power output. Any suggestions? I really don't want to tear part my engine because I need my truck for work, I am a contractor, I'd put it in the shop but I'm afraid it'l going to cost me an arm and a leg and I'd possibly have to loan my wife out for a few hours, but that alone should allow me to keep my arm and leg, considering she's a 9.8/10.

[@YoYo-tr3jg]

[@MrErikw26]

2008 F150, 5.4 4x4. When downshifting from overdrive going up a grade, I get what seems like a backfire out of the exhaust. I'm stumped, unless some of the anti-seize got into the electrodes of the sparkplugs when I changed them. it seems like a secondary ignition problem, but I thought I'd ask. could a failing phaser exhibit similar symptoms?

[@sabrom]

off the subject dp ypu have a video of DTC P0125? i can t sem to rid the mil light replaced coolant sensor, thermostat, topped of rad, and still same code appears.

[@shilohloiacono4800]

[@AlanBullock-b4u]

Do you recommend changing both phasers if only one is bad? And aslo when do you recommend putting in the melling oil pump?

[@FordTechMakuloco]

Oh yes for sure.

[@AlanBullock-b4u]

​@@FordTechMakuloco when do you recommend putting the melling oil pump on ? My expedition is making the same sound consistent with a phaser knock but it starts as soon as engine turns on

[@FordTechMakuloco]

Replace it whenever you do a timing job.

[@kenewayne1]

So I'm new to all of this "cam phaser" stuff, and most certainly NOT very mechanically inclined. I'm looking at a used 2005 f150 FX4, with the 5.4L. Dealer says that they have "fixed" the cam phaser issue (first time I'd ever heard the phrase, which led me to your video on KZbin!)...what should I be looking for when I look at the truck? What questions should I ask him about the "fix"? Thanks in advance for any reply!! :-)

[@brandonfred7426]

[@josephmattingly4277]

Just purchased a 2009 F150, equipped with the 5.4 3V, for dirt cheap. The previous owner reported that, while driving, the engine stalled and would not restart. He reported no noises out of the ordinary prior to stalling. The vehicle was towed to a Ford garage, where they spent maybe an hour diagnosing the issue before telling him he needed an engine. I'm not certain the diagnosis was correct. The vehicle is showing only P0340 and P0345 codes (camshaft sensor). The engine cranks, but will not start. Has anyone experienced a no start related to the phasers, VCT solenoids, or sensors?

The center tone vane should align with the L no matter what.

[@FordTechMakuloco]

+KlueBat I suggest phaser replacement other have tried and had concerns with power and or fuel economy then end up going back to stock.

[@charliewhitney3494]

1st off great job on your videos FordTechMakuloco this as well as your other videos are great and helpful videos. If you have a engine that has been poorly taken care of and has timing failure from crap oil this video will sure help.. A good long term solution is stop using crap oil. There are lots of these trucks with a half a million miles and more on them that have never been apart but each one of them use good oil. Then there are folks who insist on running Poison oil and put chains and tensioners and phasers in them every 60k to 80k. almost every oil you see on Tv will give you timing problems with these engines and they cost more than good oil lol they get you lured in with there tv commercials. I can only think of 3 brands of oils you see on Tv that are mid range oils and don't make buildups in your engine and Poison is not one of them how ever it keeps folks buying parts every 60k lol.pretty much if you have a timing problem under 500k your running crap oil that spends its $ on advertising not oil quality now think of what that oil is doing to the rest of the engine your fuel economy the list goes on. And they bend these folks over with a smile every oil change some every 3k miles so bad that these folks tell there friends how great the product is and even sport stickers in there windows. And Ford sits back and laughs thinking great keep running that oil we will sell you parts for life. Ford built the consumer a engine that will last a million plus miles untouched and the consumer blotched it up by running junk oil in it it even makes me laugh you can google Million Mile Gasoline Engine Teardown yet not many folks do.

[@kenni411]

what oil do you recommend?

[@Nickyguapo]

good info but idont think ill recomend buyting cam phasers on amazon lol or any internal parts.

[@FordTechMakuloco]

They come from Ford dealers selling on Amazon so…..

[@Herooftheday64]

Hey Brian, I am rebuilding my entire timing setup (with the help of your videos, YOU ARE **THE** MAN), however, I am also installing phaser lockouts with a custom tune. Should I replace my VCT solenoids even though the lockouts will theoretically render them useless? Or should I replace them since I'll be in there?

[@FordTechMakuloco]

+Kasey Rienstra if you suspect they are stuck the yes still change them

[@Herooftheday64]

I believe one or both sticks occasionally. It will chug, sputter, and it sounds exactly like the truck you demonstrated in your "sticking VCT" video. I also have chain noise on startup, so it's getting the whole nine yards, Melling 10340 pump included.

I'm not trying to start a Ford vs Chevy war but does anyone know if Chevy trucks have the same kind of problems with their engines over the last decade or so?

[@kens97sto171]

+traingp7 Dont think so. The V8 are LS based engine. 4.8, 5.3, 6.0. The 4.3V6 is based on the old small block with 2 cyl lopped off. Been around forever. The new 4.3 EcoTec V6 2015 and newer... I THINK is one of the LS V8's with 2 cyl lopped off. Mechanically the Chevy is simpler to work on... water pump swaps etc. LOTS more room under the hood.. since its still a pushrod engine... no overhead cams. I have heard of some issues on the newer ones.. they I believe have VVT on the central cam, and have CYL devactivation... there are some issues there I think.

I have a p0025 code that says camshaft position timing over retarded. My car has a knock, hesitation, rough idle, and bad gas mileage. When I unplug either Tank A or B, VCT solenoid sensor the car runs fine but still bad gas mileage. Any suggestions?

What years 4.6 does this apply to?
