I am a Bangladeshi, I like your work very much .... I am learning the work of car engine in Bangladesh, I really want to make a living by working with good and skilled teachers like you.
literally the only video I could find that was in-depth enough to make me feel comfortable doing it myself.
Thank you!
All example DIY videos should be this clear and well simplified as this one ☝️
( not giving me a lecture about how you got started or your favorite vehicle 🤦🏾♂️ get straight 👈to the point. Talk less do more. Those who disagree, you can..
Great Video!
- very well explained and procedure, thank you.
Once again great video
Thank you for the recognition
Man this looks like fun. 2 things:
1. Thought I would be playing with a different type of phaser in 2020
2. This video is calming makes you forget for a min that you are broke and so is your truck. Or else I'd take it to a mechanic.
This guy is Awesome Thank you so much for the excellent Video. It had everything I needed to know. Thanks again. RIp Wyane Static
We're glad to hear that, thank you!
@@LivernoisMotorsports Hi. I was wondering, does installing this delete make the timing chain and system last longer ? Is the engine less sensitive to low oil pressure ? Will engines with deletes last longer with less trouble and why ? Thanks
@@mvd4436 Typically speaking the timing chain system takes a beating when the phaser system fails as the shock load is being absorbed 100% by the chain and guides/tensioners. so eliminating this issue puts less stress on those items. It is also less sensitive to oil pressure changes as the VCT system requires a substantial amount of volume to work properly. the engines themselves as a whole don't necessarily last any longer, but the oil/timing systems do, reducing the need to replace them. so as much as we would like to tell you that it would be directly responsible for the engine lasting longer, the engine itself, if you constantly changed those failure points, would last a long life. But, since you are having to replace those items less frequently, it helps life for those items.
@@LivernoisMotorsports Thanks for the answer. One more question. Since you guys have seen your fair share of Fords... When you lock out a 2004 or newer Triton , does it become as reliable as an old 2 valve Triton generally speaking ?
Im looking for a truck and I never had problems with 2 valve Tritons. But the phasers are almost pushing me to buy a Chevy. If the locked out 3 valve is close to as good as a 2 valve, I'll just buy a good used Ford and send it to the shop to get locked out right away.
@@mvd4436 We feel it is, the only issue left is spark plugs on the pre 08 engines, but just changing them every so often is a big part of if you will have issues. But to be fair, 2v engines had their own spark plug issues too.
Very good instructional vid!!
Great video, keep up the good work.
I wish every mech was like this guy
kquigs100 If flat-rate didn't exist then every mechanic would work this way. Taking time to do the job carefully, resulting in the job being done right the first time. I wish I didn't have to rush through jobs just to make a living. If I was being paid by the hour, I would make sure every damn bolt, nut, and screw were torqued to the proper specification or the proper sequence. I would only get paid 4hrs for this type of job. That's $80.
Cannon Krebbs hey are you a mechanic i dont mind paying you good money put make sure my vechile repairs are quality do you want to work on my f150?
Mostly every 5 out of 10 machanics want to ripped you off
Not Doing it Right and saying they Did put the New Part's in. It's just the fk'n truth. They Kno it's a pricy
Job . And need lot's of patience .
Like I said there are Good Machanics out there. Just need
The Luck to be on yourside to find
Right one.👍
Gracias por compartir su valioso video estoy muy agradecido amigo
No problem! Thanks for watching!
This was GREAT!!! It just made me realize I shouldn't do this myself because I work too fast and I will miss a step....smh
Very good video. I noticed that you did not remove any of the valve springs. I think the ford manual requires that 2 valve springs be removed to keep the cam from spinning once the phaser is removed. I guess when you put the phaser back on you can spin the cam back to where it should be by aligning to your mark.
This video is 5 stars good stuff man you did it so professional
Thank you for the kind words!
this is great instructions
Very useful thank you
great product I've installed 3 so far they are pricey yet quality always cost and I haven't got any complaints of either of the 3 ever having the same problem again its been 3 years for the first one so like I said great product
No check engine light with these? I've gotta put them in a friends 5.4

@@garywalker2575 thats crazy. You got robbed. It in no way takes that long. But I can see shops charging that. Best to do it yourself. May take you 1 hours per side if your being slow and safe.
This is the wrong thing to do by useing lock outs. This engine was designed to use phasers to in crease POWER and gas mileage. i tied this, not as much power up-hill gas mileage went down.
If properly done, this is not the case. These increase power and mileage compared to poorly functioning phasers, which on a 3v is 90% of the time, even with brand new parts on an old engine, and the calibration has enhancements required when making it a non-vct equipped engine.
$700 for a $20 chain tool, $20 bolts and two pieces of aluminum that can be had for $15. Oh, and a "tuner" that anyone with HPT can do for a $100...assuming one even wants to bother with it. Noice.
And don't forget hundreds of thousands of dollars in emissions and durability testing to ensure it was 50-state legal and foolproof for the end user.
It's easy to devalue something when you ignore the cost it took to develop and certify it. That's the difference between inventing, and copying.
That's why it earned a patent, and 50-state legal status.
@@LivernoisMotorsports People were doing it with bolts, or any other piece of appropriately sized metal, 18 months after the Triton hit the streets. You didn't invent anything.
@@scottysgarage4393 Considering this was released in 2004, within 6 weeks of the official launch of the 3v family of engines, and featured heavily in our very early build 2005 mustang featured in motor trend, I'd say you were at least 16.5 months behind the curve. The CNC program was written before the first retail vehicle was ever delivered to the dealership.
I don't know how loud I'd broadcast you were shoving random bolts and pieces of metal into customer's engines. Especially when there was a purpose built, precision machined solution in the marketplace at that time.
@@LivernoisMotorsports Been doing this for nearly 40 years, moving millions in inventory every year and never heard of you before stumbling across a random vid. But you keep tooting your own horn, I'm sure you occupy what, 1% of the market with those prices?
Motor Trend. Cute. Do people still read that rag? :)
@@LivernoisMotorsports
? Do you have to do the other side aswell in all videos i only see this side
Truly iconic
Ive watched your video a dozen times until I fully understood the procedure. I have a 4.6L in my 2009 expidition, its no secret that the phasers get worn out at 100k miles. Question: What is the benifits of phaser lockouts ? rather than installing new phasers ? Thank you again for posting this video, its detailed instructions are perfect for the do it yourself person and I look forward to your reply.
+Silicon Valley Engineer Replacing the phaser actually doesn't address anything in regards to the failure point in this system. The phasers operate off of oil pressure supplied by the engine. When these engines wear, and age oil pressure naturally drops. Because of this, the phaser no longer has sufficient oil pressure to operate correctly. Now, the oil pressure is plenty to still operate the rest of the engine safely, but not feed the high demand of the phaser. The reason you see people claim that replacing the phasers helped is that you have a brand new part with zero wear on it, so it's operating at maximum efficiency, but since it has to pick up the slack for the rest of the engine it can fail within hours again. This is why our lockout is the only permanent fix for the phaser system.
+Livernois Motorsports Very interesting discussion, thank you for your reply.
+Silicon Valley Engineer You're welcome
Will the lock out fix a bad phaser? Or is the lock out designed to prevent failure of a good phaser only?
This is designed to work in either situation so long as there is no physical damage to the phaser itself.
Wouldn't this cause error codes to be thrown by the check engine light??? Seems like this is a cheap hack but not the way to go long run. Just my two cents.
Our kit includes our 50-state legal mycalibrator tuner to do this properly, and is the only permanent fix for these.
Jeannette, do you mean you have two trucks? Or are you asking if you need to install this in both phasers? If two trucks are what you are referring to, then you need 2 complete kits. If you are asking about if you need to install the lockouts into both phasers of one truck, the answer is yes.
nice sharing~~tks a lot!!
when u pull phaser, wont cam move? or equalize
Excelent brother....
Daniel Salcedo thank you!
Why did the cam shaft have to be locked into place? Other videos ive seen said the cam shaft will move when phaser is moved how do you get it to where it wont?
At this position the camshaft naturally stays located.
what is the purpose of the lockout
+miguelito0725 sanchez by locking out the variable valve timing you can run a bigger cam and avoid piston to valve problems.
+ratcamaro Very true. That's how these started their life back in 2005 when the mustang first used the 3v engine design. We determined before anyone else how to address this and why its necessary. Our own 2005 mustang that graced the front page of motor trend magazine featured our lockouts even.
Livernois Motorsports & Engineering Do you need to reprogram the PCM to avoid any codes popping up now that the phasers don’t move?

Featured snippet from the web
Designed to be an affordable alternative to expensive engine repairs, the cam phaser lockout kit fits Ford Triton V8 engines with 3-valves produced between 2004 and 2014. ... "Lock" the cam phasers into one position, ending the rattling problem and preventing future damage.
ajthib yes you do need to have a custom tune.
very interesting
Since you never used the tuning device in the kit during the video is it necessary and could the kit be sold without it for several hundred dollars less since it is just a couple small pieces of metal and a hunk of plastic? It is very expensive and seems much like price gouging. Make it affordable and you may sell alot. At $700 for that kit for me it is not even an option
The recalibration of the computer is a 100% necessary part of this repair. Without it, not only will it have a check engine light, but it will also run in a default mode, and have poor drivablity. I apologize that you feel the price is not fair, but we have a tremendous amount of r+d time, as well as CARB EO status, and is fully patented due to it's unique design.
Chad Preston: Part of the procedure is ensuring the cam is in a certain spot to prevent this.
@@iwontturnuhomo No need with our kit as it disables them
What's the tuner for in the kit you are selling? Did not mention anything about it in the video.
Cody Jiron It's our MyCalibrator tuner.
will this affect the smog test ? ....well made vid thanks
Our kit is 50-state legal with our mycalibrator tuner
I did the cam phaser lockout on my 5.4 L three valve, and had a question about it.
Once the lock outs are in, is there any reason why the spring and plate on the back of the phaser still need to be there?
i’m not a motor engineer, but I do have a solid engineering background it seems like the outer plate is mostly there to provide centrifugal force that shifts the internals.
Once the phaser is locked, does it need to spring at all?
What are the flaws of a lockout? Mines in the shop rn for that
The spring is not needed, no. But, we put it back on to prevent potential confusion, or loose pieces in the engine if forgotten/lost.
Is this the same procedure for the phaser limiters?
Yes it is
@@LivernoisMotorsports cool. Now I just need you guys to send me the limiters I ordered back in February.....
@@302hobronco All back orders shipped earlier this week, so these should already be on their way to you.
Does it have to be tuned??
Yes it does, our kit includes our 50-state legal tuner to compensate for the lockouts.
For what reason would you want to lock the cam phasers out? I know they are a weak point on this engine. Would doing this cause a loss in power and efficiency? Or would it not make much difference? A friend of mine has a 03 F150 with this engine. She's replaced the chains & the phasers in her truck. That truck doesn't get great mileage to begin with and it runs great. Hers is 4wd. Gets about 16 mpg. Probably 19 - 20 freeway.
The reason it to permanently eliminate the possibility of phaser failed which could cause severe engine damage. Most people report better power and economy over failed phasers.
Besides the obvious of noise reduction and reliability, what are the effects of doing this lockout? I would assume less power?
Actually you would get more performance out of it. That's why they recommend running a tune.
Do a complete timing job when doing the lockouts. Tensioners, vvt valves, chain guides and a new oil pump. You'll get another 100,000 miles or more.
If you have an engine analyzer can you do the tune up procedure after installing the cam phaser lock out using the analyzer?
If you're talking a scan tool, no you cannot. Our complete kit comes with the necessary tuner and calibration.
How do you take care of trouble codes of inoperative Variable timing after locking the phaser? Is there a tuner?
this package comes with our MyCalibrator tuner which makes the appropriate adjustments to operate with locked out VCT
Is this to prevent your cam from going bad or can you lockout a phaser that has already gone bad instead of buying a new one?
so long as there is no permanent damage to the phaser or cam, yes it would
Doing it this way do you have to remove roller followers? What are the steps for the tune?
You do not. www.livernoismotorsports.com/images/3_Valve_Cam_Phaser_Lockouts.pdf
Do you need to make sure the cams are at 11 oclok or it doesnt matter what position the cams are facing?
you need to get them into their properly timed position as the video demonstrates, the exact position will vary based on the version of phasers and chains you have.
What is this phaser lockout for?
So all I need is this special wedge tool and I can remove the phaser without messing with the rockers? Can I buy just the wedge tool?
Mxmxv43 That is correct, the wedge tool allows for removal of the phaser with no other component removal. As for selling it separately, we do have the tool by itself.
How do you prevent camshaft from turning while removing the phaser?
By rotating to the indicated spot as in the video, it stays in place. But we always recommend marking the sprocket, chain, and cam just in case.
I dont know how they even designed these things.
one question you need to buy at new. tool after the fix. ???? electronic. tool???
Question so now I don't have to use the oem phasers from ford and I can just buy a cheap one ?
THE EASIEST WAY TO FIX ..... ya but lock it right away! I’d even take it apart first and reassemble it with lock tight bcs I’ve seen these come apart inside the engine
What's the use of this blue piece that's been fitted in the gear?
That is the lockout, which changes it form variable cam timing, to fixed cam timing and eliminates the "rattle" noise and fault that is common with these engines
We are considering this for one of our fleet trucks, just trying to find a mechanic that will do it.
One mechanic said it is too late (we just started feeling some rough idling this week). This is a better option than engine or phaser replacement and honestly probably worth a try. Thoughts on it being too late or is the mechanic just trying to sell me an engine. Btw if I can get even a year out of this it’s a huge win.
Typically it's only too late IF there is damage to the camshaft and phaser dowel pin area, and that usually takes a long time of ignoring the codes and noise. So if it just started, while it's always safe to inspect, that's highly unlikely.

Great video very thorough!
Just bought a f250 witht 5.4 3V. This might be a dumb question but why would you want to install a lockout to the phaser?
Since, eventually, all 3v engines eventually have the phaser system fail, the lockout prevents or fixes this failure. Preventing the associated knocking sound, poor idle quality, reduced performance, and potential engine damage that comes along with phaser issues.
@@LivernoisMotorsports thanks, I'm assuming you would do this to both phasers?
Now can you install the lock outs to brand new phasers? Or do you have to wait till they get worn out and start knocking before you install the lock outs?
You can definitely install them in brand new phasers, and we sell them preinstalled that way.
@@LivernoisMotorsports so aee yhey going to have a longer life span ? will they eventually start knocking with the lockouts in ghe phaser of do 5he lockouts a permanent fix to the ticking?
@@manueltovar4821 This is a permanent fix for the phasers, if it starts knocking it will definitely be from a different source.
hello everybody,, is there any suggestion to dont let move the camshaft once we are replacing the camphaser?
+ivan noyola If you follow the procedure outlined, the camshaft typically stays in place. Others have suggested for extra insurance, simply remove the rocker arms to remove all load from the camshafts, just bear in mind that there is nothing preventing their movement now either.
Excellent demonstration. I'm still learning my ABC's on this dreadful creation by Ford, but why and how does a locked cam phaser help?
A locked phaser completely eliminated the vct system, therefore there's nothing to fail.
does this have to be done to good cam phasers or can it be done to cam phasers already making noises??
It will work on cam phasers making noise
I live in texas dallas area im looking for someone who can fix the cam phaser noise on my 05 expedition runs perfectly smooth lots of power just the noise gets on my nerves
Antonio,
This is a package that the average repair shop can handle. We provide complete directions, and a turn key solution for this common problem.
What if the long bolt is not protruding on the spring side of the phaser at the 3:08 step? I can see the hook spring coming out, other 3 are clearly not, last one "may" be hidden by the timing reluctor. Any idea?
Is your Phaser an aftermarket? or OEM Ford?
Do you have to do it to both phasers or just that one side?
Both sides must be done
Do you do this to both sides, or just drivers side?
both sides are required
Why are these phasers ticking and what part on them is actually making this noise.???
+MrMus TangMan They are ticking because they have lost control of motion due to a reduction in oil pressure. The noise is emanating from the 5 vanes quite literally smacking the built in stops in the phaser since the motion is completely uncontrollable
So this kit is the fix for the phaser knocking?
Dave you would be correct sir! If you want to place an order go online or give a call at (313)-561-5500
Is there any tuneing to go along with this I have a 3v 5.4 with a banks tuner can I run the lock out with my banks tuner
Our package will work with any existing program in the computer as it extracts the current file and makes the necessary changes.
do you have to set the engine timing to a exact position to take the load off the cam before removing the chain? i would be concerned that the cam would want to move due to the valve springs to an unloaded position.
Mike Brennan Mike,If you would like, we could email you a set of directions so you can gauge the difficulty level yourself. Please email is at info@livernoismotorsports.com

Installed the lockouts and ran the programer. The truck ran great and no noise but the pcm went bad and I replaced with a new pcm. Now I have tried to reinstall the lockout program and it comes up with an error message. Is this a one time download to the truck from your programer and if so how do I resolve this issue?
Lynn Lutjen This is indeed a one time download, feel free to contact or tech department to attempt to find a solution.
Good day , please indicate the number of a party, I buy both the part to lock the chain, and the piece to insert into gear , I'm from Venezuela , I appreciate the information , and the video presented, my name Renzo Micolta , Thanks
Great video and very detailed thank you. Is the cam phaser only on the one side or does this need to be done on both sides of the engine?
Thank you! both sides.
Can you re-use the wedge for a wheel chock on a grocery cart?
No they are wedge to yield. One time use only.
Any videos of an install of the limiter set you sell?
it would be near identical, save for the limiter being a multi-piece design, the same principles apply.
@@LivernoisMotorsports Some videos when replacing the timing components recommend clamping the cam in place (which seems like a bad idea) but you all didn't use anything like this. What keeps the cams from turning in this procedure that you all did vs the rest out there?
@@brianw7731 we got it to the natural resting position prior to disassembly, but usually you can lock it in place with a wrench on the flats of the camshaft.
Will this lockout or limiter work on the new designed phaser because internally there slightly different shape??
We offer Ford and Dorman style phasers lockouts, and they work on all variations of these from 04 to current.
@@LivernoisMotorsports just lockouts no limiters???
@@brandonross9711 We do offer limiters as well, but they do not fix the knocking. They are for larger aftermarket cams. We only make them for OEM phasers.
solution don't buy a truck with that damn engine
That's a damn good engine... 0ver 360k miles on my platinum no issues till now little loss of power and I believe this is to blame and seem like a simple solution
Where do i buy this kit ...
Marks the mark on the phaser and marked chain link........ ?????? It was marked already!!!
when you face the engine, the cams rotate clockwise. The clockspring in the phaser retards the cam, oil pressure from idle up advances the cam, for better low-end grunt. Your positioning of the lock out is creating a full retard condition. Shouldn't it be full advanced, since 90% of driving is under 3000 rpm?
The phaser, at rest, is fully advanced, and the lockout keeps it a full advance. It uses oil pressure to retard the camshafts, and this eliminates that function.
@@LivernoisMotorsports I'm looking at the rotation, and seeing it to be opposite. Sorry, but you've got things backwards.
What will happen if you dont tune out the vct solenoids? Could it cause my oil pressure to drop to 0?
No, but it will set a check engine light and run in default mode and limit power.

awesome video thanks guys ! quick question do you guys do the install kit as well i have almost 190k and starting to hear the chattering whats it gonna run me to fix it before i have to replace the motor ?
Are you asking if we install this kit here at our facility?
Boosted QR25DE new phaser gear still noisey! Can I lock it and run it the same? Is it safe
give us a call and we can discuss all the options 313-561-5500
So question, I read that locking out the phaser will lock it in the full advanced position. Don't we have a kit that will set the cam at zero degrees so there's no issues?
Will this work for 2011 expedition 5.4 v3
Yes, our system is available for these as well
Customer of mine has an ‘08 F-150: If a 5.4 3V is already idling rough and throwing codes, are the existing cam phasers going to have to be replaced before installing this lockout kit, or can I just use the phasers that are acting up since they will no longer be able to rotate internally?
We always recommend inspecting them for damage, especially around the cam dowel pin area. if they are undamaged, there is no need to replace them.
@@LivernoisMotorsports Excellent, thank you for the fast reply!
I have a 2002 f150 5.4. Is it a 2 or 3 valve? If its 2 valve, do they have the same VCT issues and if so, will this exact same product work?
that is a 2v, the 3v engine did not launch until 2004.
will JB Weld work in the place of the Lockout module 😂
It least just for a little while 😉
It will not unless you needed a quick fix to make it home as an example. We don't recommend doing this be best to purchase the cam phaser kit to fix that.
QUESTION...Do you recommend putting lockouts in brand new phasers?
I'm waiting on my new parts from the U.S. to come in. My Ford phaser was out 90° causing a really bad idel then a crank no start.
Thanks 🇨🇦
F150 5.4 L 3V 2006
Yes we do, that is the safest way to address these, by ensuring there is no damage to the old ones.
GOOD FRIEND TO RECEIVE THE KIT NAME THAT PROMOTES IN THIS VIDEO
On mustang 4.6..
When you are torqueing the phaser bolt to 30 ft/lbs then you do the additional 90 degree is it fine that I did the additional 90 degree with my brother holding the engine with a breaker bar so it won't be able to spin or is that over torqueing
I have a 2006 Mustang GT as a code of peas 0012 I changed the cams to comp cams and now that code won't go away.. I've tried a number of things including camshaft phase or lockouts that code still comes up I'm questioning maybe my brand new chain tension or or possibly the oil pump itself not enough pressure?? Timing chain Fraser's guides are all supposed to be new?
Unfortunately there is far too much going on to diagnose by description. It could be calibration related, spring pressure related, actual cam timing related, damaged sensor, etc.
I have only one long bolt, holding the spring but not a long one behind it, what's going on with that?
If it's an aftermarket replacement phaser, the design may differ
Very well done video tutorial. Thank you!😊
Hello, I have a problem with a 2008 F150 5.4L 3V. First problem, when in cold and starting the motor sound a chain noise, the technician said that is a CHAIN TENSIONER on the passenger side. Second problem, it thrown a P0022 code (INT CAM POSITION TIMING OVER RET BAN 2), its misfiring the passenger side and the technician said maybe is a phaser... The truck was repaired of a time chain kit 2 months ago... those problems I have sounds awful and the motor starts to vibrate... I saw a lot of videos on youtube that adjudicates the problems to VCT Solenoids... and maybe could be those, but I´m not sure... What do you think? Could those Phaser Locks help to solve my problems??? For what are those made for??? What are they improvement for the motor or what is the benefits? Hope you can help me with this!! What happen with the CHECK ENGINE light? This light will keep on????? Thank you!

RESPONDER
From what it sounds like, it is in need of our phaser lockout system. The main improvement is that you will never have another issue with the VCT system at all because it bypasses it, making it operate like a traditional fixed timing gear. Our package comes with our MyCalibrator tuner, and the corresponding tune changes to make certain the engine runs properly with the VCT system eliminated. The only reason the Check Engine Light would come on is if there was a legitimate issue outside of the cam phaser system itself.
What is the lockout for?
This is to prevent movement in the phaser, which is what causes the noise and engine damage from excessive movement.
Perfect explanation!
Well I would have purchased this kit before my 3 valve out of my ‘04 F150 bit the dust because of these phasers. Can I replace it with a 2 valve engine instead?
ajthib Unfortunately not easily. Almost everything from computer, to harness, as well as intake and exhaust are all different.
Where do I get the wedge to lock the chain? in Mexico city
ISRAEL ANTONIO This is included in the system
So I got to thinking on this whole cam phaser issue on the 5.4L . So wouldn't just getting a new torque bolt fix the issue for another 100k? I know the lick out is a more permanent fix but it seems like the bolt getting out of torque because of the design flaw is biggest prob and may stay good after replacement for 100plus miles. I'd be fine with that for a $10 part.
Technology on the Beach No, the phasers lose control due to reduced oil pressure that naturally happens as the engine ages and wears. The phaser itself, along with the timing drive, and fasteners have nothing, or at least very little to do with this phenomenon. That's why replacing the entire drive system with new components maybe lasts for 1-15k miles before happening again.
