Love the paid version of Forscan for android!
What do think about the melling roller rockers and lash adjusters are they trust worthy for the 5.4 3v eng..
2006 lincoln navigator with obd code P0354. Changed voi, spark plug and still misfire. Has plenty of spark. Any ideas
My cylinder 2 says one count misfire, so how often could it be occurring?

Ford owners in your area are so lucky to have you! Your a Ford Tech. Magician
yes there are i give anything g to have a mechanic like this in Texas
We need him in California. I don’t trust any mechanics at all here unless they are friends or friends of friends, other than that they will replace everything but the issue 😂
I'm not a mechanic but I love this guy's channel and I can participate in conversations about 5.4 3-valve motors. I drove a 99 F150 5.4L Triton V8 for 19 years, then a 2018 F150 2.7EB and now a 2020 F150 2.7EB. Fantastic channel and work! ps. In high school a drove a 78 or 79 E250 with a 460 in it. Replaced the water pump myself on that. Talk about no room to work.
I worked for ford for a couple of decades and am the only guy in my area that fixes the 3v pigs! Everyone else throw parts at them. Relative compression and power balance should always get you off to a good start. I have an ids also and it helps a ton especially if you need to do the updates which we always check on every vehicle. Most of us car guys can hear that uneven cranking every time. And know it's a compression loss. Keep up the good videos!
Some people swear by the 3v engines. Others swear at them.
Good time to demo a boroscope camera’s cabilities. You might even be lucky enough to see a piece of ceramic or burnt valve. Then there’s always the cylinder wall and piston top. 5 minutes to help ‘visualize’ the big picture - pun intended. Great diagnostic process👍
I want to tell you thank you for your videos. Your videos have helped me replace two engines, with no previous experience. So thank you! So much!
As always, you my man are awesome! Thanks for taking the time to post these videos. You've helped so SO many people out with these vids. Always learning something new from you!
Ever since I got my '06 Expedition I've been doing all the services by myself, the previous owner doesn't knows anything about cars or mechanic issues so he sent it to the dealer for every service for 12 years! Until he decided to sell it to me, I'm the second owner and man, I've been following all your video tutorials related to the engine on my SUV and I've saved a lot of money! Nothing serious or anything to be worried about, the engine has less than 100K miles on it and it runs beautiful, not a single issue even to this day and for me is just taking care of the regular maintenance but with your help and knowledge this is even easier! Thanks a lot for all your help and precise instructions!
Great camera work also, you show great detail on what you are doing. Thank you for taking time to make these videos, because I know that puts extra work on you.
Another fine video sir. I am the Ford Whisperer I am today because of your channel. I have learned volumes from you over the last several years. So for that, thank you Brian!! 👍👍
Wish I could drop my truck off at your shop for a full refresh and once over. So tempted to get a new one but reluctant to let my old one go. Keep up the good work
My favorite test, no if buts or maybe. Used it a lot in my Mechanical workshops. Good to see you using basic old school stuff.
All said and done, it's suck, squeeze, bang and blow.
Regards Steve.
Awesome video, thanks for putting out such high quality vids, cuz of you I was able to change my plugs, even when 4&8 broke. Next upgrading oil pump timing chains and all that good stuff
Thanks Brian that was a great walk through on the diagnosis. Very thorough.
My 5.4 3 valve has 172K and counting with no issues. Great video as always
Another good video - I performed many cylinder leakage tests back in the day. This is great even good for piston aircraft engines.
Quality Diagnostic! Seem to be getting a bunch of those here lately.
5.4 is a boat anchor not surprising
I recently did a timing job on a 2007 f150 with the 5.4. After the repair it had a fluctuating idle, checked and found that it had broken a spring on the #5 exhaust valve.
Awesome test example results!!! Thanks for the tutorial!!! You’re the best, Bro!!!
Really good video on diagnostics, as usual. Thank you.
Very informative videos.
I learn quite a bit watching your channel.
Great instructional video, thank you! That broken ceramic insulator rates right up their at the top of the rare events on the weirdo meter, makes a guy wonder of a close visual inspection of the plugs prior to install would have caught the problem. Boy would the consumers out there benefit if auto repair shop owners and their technicians studied the full range of repair videos you have produced.
Very interesting presentation, and nice walk through on the process. Enjoyed, cheers!
Excellent video. I really enjoy diagnostic videos
Wish you were here in Sacramento. Your not only very capable, your trustworthy. Hard if not impossible to find in this area!
Thanks Brian for another great video, thats what I need to do to mine. "The air test"
Love your videos thanks for sharing your time and knowledge
Great diagnostic video. Very informative.
Keep up these awesome videos! For the 5.4 3V they are bittersweet. I own a 2006 F250, haven't had any issues with it, but at least if I do I will be more educated after had watched all the 5.4 vids. ;)
Dude you are amazing, love your videos.
Absolutely amazing job!
Diagnostics are what separate a mechanic from a parts-swapper.
good. waiting for next the vlog to see the result thanks Brain.
I have the 4.6 doch Intech; I just did a timing job sprockets and all and it runs great on startup.
3 to 5 minutes later it starts ticking and after a little while sounds like a dry bearing.
Thanks to your videos I will be checking all my lash adjusters and rollers., But I think I have an oil circulation issue.
You are very informative I love your channel
Nicely done Brian!
Awesome insight, definitely a learning experience.
Riley excellent diagnose good job 👍
Great info I soon will be doing a timing kit on my 5.4 3v thanks to your videos, give us an update on that truck if you're fixing it..
Excellent video Brian thankyou
What an excellent video!
Thank you, Brian.
Excellent Diagnosis 😀😮😀
This guy is awesome thank you for your videos
Thanks for doing this, I've had a persistent Cyl 2 and 7 misfire on my 3v 6.8 -- it can be a real pain. I didn't know the diagnostic tool had those menus, need to find someone to look mine up for me.
Thank you for sending me this video
Makuloco keep the good work man nice one
Nice test technique. Will give that a try …
Beast mode Brian
Another great video!
I did the entire timing chains, Phasers, VCT, Oil pump etc from your videos and my 5.4 3V purrs like a kitten now.
I bought one of your shirts cuz I feel like I'm on the team now!
God Bless you!
Great diagnostic. Most guys would just throw a plug and coil at it.
And that is the problem with the automotive world today.
Absolutely a great video.
After going through a nightmare with a 4.6L, I discovered that the intake valve was "cupped" which made the valve stem too long. This would not allow the valve to close completely. A quick fix is to grind off about .50" of the valve stem. Either that, or remove the head and replace the valve. This valve became deformed due to a misfire that created a lot of heat. An intake valve should not be getting that hot since there is air flowing over it all the time. After the compression was restored, the cylinder is firing normally and the valve should not deform any longer. It should last. The only way to get this cylinder to seal, with air pressure in it, was to remove the rocker arm. After measuring other heads, to see how tall the valve stem was, I determined that there was around 50 to 60 thousands of an inch more valve stem on that intake valve. I ground it down, with magnets and rags surrounding it. Put the rocker arm back on, and had compression. Happy Dance!!!
Enjoyed watching👍🏻🔧
It would be nice to see if a piece of ceramic is holding the exhaust valve open and/or if the valve and seat is damaged. There are a ton of cheap boroscopes with all types of attachments now. =Should be able to get a picture of that valve.
Crappy quality control = shit like this will happen.
Your diagnostics for this were right on the money and you did an excellent job of displaying the true situation. This truck is probably a simple valve fix = not that bad considering your diagnostics pointed directly to issue and you didn't waste time getting to it. All the plugs are garbage and I would replace them for sure.
Awesome work
It's a bad Monday for someone right now
For sure.
His rear fenders are rusted out too.
Hello Brian, I’m hoping you can help me. I’ve been working so hard on my truck to get it all fixed up after I paid a shop to do the timing and they used nothing but cheap parts and all my timing components started to fail less than 3mo after the repair. I watched your video series on the timing job and I want to say thank you for all you do to help us 5.4 3v guys. The problem I’m having is a misfire on cylinder 7. I timed the truck perfectly following your video and using the OTC tool. After I finished the timing job, everything was good until after about a day when I went up north to go snowboarding and the next day after I got home, I could feel the truck having a slight miss. I’ve replaced the spark plug, I’ve replaced the coil, I’ve replaced the fuel injector, I’ve done a compression test and all of my cylinders are around 195psi. What else could be causing a misfire on just the 1 cylinder? I checked my roller followers since I replaced all the lifters and followers with new ford performance ones with the updated design. I replaced the oil pump with the Melling 340HV, I installed brand new ford phasers, I used the metal chain tensioners out of the Mustang GT which I did modify the ratchet by filing down 2 teeth to allow it to ease tension when the truck is off. The misfire seems to go away after the truck gets to operating temp which made me think it could be a piston ring but no oil present on plug and the compression is nearly the same as all my other cylinders. Please help!😭
Thanks for sharing... Cheers.
Thank you Sir for all your vids! Helped me out numerous times!
I have an 01 F150 5.4 2v with 346K on the clock. Kept up on the maintenance always.
Still runs strong!
Same here,2003 expedition 5.4 2v 200,000 and still going
Wow
She still running? You gotta be at Almost 400k now eh?
Great content
U are So Awesome thank u so much for ur Time and everything U do!!! U are the Best Man. 😂
I have an 06 f150 5.4 with 94k miles. I’ve been religiously using full synthetic oil and babying it it’s whole life. It runs like a champ so far. Changed plugs at 60k. Should I have anything done to it before it decides to self destruct. Thanks for the awesome information you’re giving us.
You are good a master l am always looking for video you made good luck
Before anything do a cylinder leakage test. Look for bubbles in the coolant listen for air escaping in the crankcase, intake, etc...
Good find
Good find for him maybe not so much for the customer though....... Expense repair
good job
Cool video 😎 i just noticed today that my Snap On Solus Edge doesn't have the power balance option test🙄it was a 05' Expedition...Snap On gets on my nerves🙄
The Ford Dr. is in!
Thank you
What a cause man ... wow
Damn. That is so cool.
Good job
Thank you!👏🙏
Hey B0$$! Long time no see. Again my most sincere thanks for the awesome videos.
Dang. Looks like the guy kept up with his oil changes well by the way it is so clean. Sadly, that's not enough to make those junky 3V motors last. Or maybe happily, since I paid for my second house by working on them in the shop. Perspective I reckon.
Will this scan tool you're recommending do a Power Balance test also curious if it would do an ABS brake bleed
I’m a ford guy, but ford had a lot of problems with these kind of engines from 2004 to 2010 with the 5.4 liter. I have a 2000 Ford F-150 with the 5.4 liter but nothing to compare with those years. Mine it’s been a very reliable engine, I think from 1997 to 2003 they were excellent engines till this day and mine is proof of that.
Your 2000 5.4 is a 2 valve not a 3 valve
Same her bubba, 03 f150 4.6 2v iv drove basically every day since may of 2006 got over 400000 miles and still going as my primary work truck which really means daily driver in my world
2003 ford expedition 5.4 2v ive got 200,000 and still going strong,fordmakuloco has helped me with the maintenance on this vehicle this guy is a FORD GENIUS
4.6 2v with 265,000....20 years old and runs great.
Until the head gasket blows on the right bank lol
Thanks
Hey there @FordTechMakuloco love the content! Question: I have a ‘12 single cab f150 2wd 5.0 133K miles 3.55 rear end and last week it was loaded up to max trailer weight.. was squatting pretty good but still had a little bit of travel.. i was in tow haul mode.. when i would take off from a stop or when i would accelerate more when going up hill the truck would shudder/vibrate the more i stuck my foot down and would stop as soon as i leveled out or got to my desired speed and started cruising.. any ideas what it might be? This is the first time it’s ever done it and never does it when it’s unloaded or lightly loaded.. this was the first time i was ever at max or maybe even slightly above max depending how much the trailer weighed (it was a rental)
This happened to me on a 4.6 3v on my mustang. No compression on cyclinder #8, when I pulled the plug it was broken! Never dug in deeper just bought a used engine with 41k on it, but I was very frustrated. Didn’t know plugs broke like that
Great video very informative. I have a question though. What if you didn't find the broken piece of the spark plug and everything looked normal including the valve terrain?
Nice !
You are great
Great video! What software are you using on your computer?
Thank youu
Mind-blowing that such a small device could cause so much engine damage 😬. Was it a poor quality spark plug? If serviced by a dealer would that be covered under warranty?
This video hits very close to home Recently Iv had a tick that Iv been trying to figure out what it is . Long story short it was a loose plug Which were new plugs from about 6k mikes ago Which I paid my mechanic to do Since I was afraid of breaking them
He got them all out without breaking With all the little ticks and noises Iv fixed it was hard to pin point the tick but looking back it got worse or started after the new plugs Well I guess one of the plugs was loose for awhile It seemed to run the same strength wise So I finally found the loose plug and tightens it Power went down Then I inspected the plug to find the metal u shaped ground piece missing So I vacumned out the cylinder and put in a new plug Power went back up to what feels like normal Never got a code or anything yet ! What are your thoughts on the metal piece ? My mechanic said it probably passed through the exhaust I guess I have no clue if I vaccumned it out but I guess it would have been passed through some time ago
Can't believe all these problems with the 5.4... I own 2 2008 E350 super duty vans purchased with 100k on them and they now have 604k and 569k and have never been opened up for repairs! Plugs,coils, filters, belts, and Mobil 1 synthetic oil.. that's it! Still running 2020! Original Fuel pumps!!! Original starters!!
Just for kicks, I'd try to look inside with a bore scope to see if there's debris holding the valve open. Then, I'd strike the valve stem several times with a brass drift and hammer to see if the porcelain could be shattered into smaller pieces. If the valve isn't bent, this might work to blow the pieces out into the exhaust. Who knows? It may fix it. Looks like the truck is rusting away, so it's still worth trying and if this didn't work, no loss.
Oh he’s been driving it like this for awhile now so it’s over.
@@FordTechMakuloco I replaced plugs and coils about 6 weeks ago....with Motorcraft plugs...3 weeks later had a misfire on one cylinder...mechanic pulled plug and the metal tip completely broke off. He replaced the plug and it ran fine for about another 3 weeks and now i have another "random" misfire he says and he doesn't know the cause other than thinks it needs timing chain kit now. Do you think the broken off plug tip could have done something similar to one of my valves ? what's the chances it blew out without damaging anything ? TYVM !!
I need to take my truck to your shop asap.there is no good machanic here where I am at .
Nice video. Looks like they could have changed the oil a bit more often.
You are the best.
You got me through replacing the throttle body on my Freestyle. Thanks for the help.
I’ve had my VCT’s repaired at the dealership. Oil seepage coming from the back of both valve covers. The seepage was observed and noted however it was expressed to me that such is not uncommon. A few oils changes and spark plug/tune up service later I began seeing more oil building up. While looking around with my flashlight I saw oil il in my spark plug wells. Dealership reinstalled the gasket/Valve covers however a month later the oil seepage is back. What would cause the valve covers to leak? Likelihood of this being failed parts vs improperly installed? Thank you.
I did replace the oil pump with a 360hv and both VCT I do have two codes p0506 and p0011
Great video on how to correctly diagnose a trouble code. Why wouldn't you use a rubber mallet to bounce the exhaust valve open a little and try to loosen and free the debris that's keeping it from closing, while blowing the air? Ty, subd.
I saw a champion plug do that once from being loose and overheating. In that case it did ot wreck the valve but it wrecked the rings instead... even worse. They got off easy compared to that.
Where would you recommend sourcing a reman 5.4L 3 valve engine?
@FordTechMakuloco just FYI, that ignition coil brand design is Duralast from Autozone. They started adding that new design recently on some of their electrical components. Just for future reference.
Yeah I am not familiar with the aftermarket, its all ford here.
What would cause air to come out if the intake (kinda like a back fire ) when you hit the throttle hard.
