I’m on my second new edge Mustang GT with the 4.6L 2V. Not a power monster but they have been such good engines to me. I’ve driven them both hours and hours non stop higher RPM range and they never skipped a beat. The only caution with a 4.6L that’s almost two decades old now is the timing chain guides get worn and the tensioners bust through them. If you take the oil cap off running and here the chain slapping it’s time to pull the cover before it takes the motor down.

Been following you for a long time, great stuff! Former Ford tech, moved into service management, dived for the hills just as fuel injection was coming on but have never been able to chase the gearhead outta me, lol! Work IT now, it's ironic that all of my new skills are transferable too. Had a '13 150, 5.0. cyl 6 started missing intermittently around 100,000, put up with it until 200,000, then it became a daily occurrence... low, rough idle, check wallet light on at every stop. Found cyl 6 had 90# compression, grrrr. Put a tuner on it to raise the idle speed, Torque to kill the check engine light often, and drove it another 100,000 miles. Down a little on power, but I spend most of my time on the highway anyway and it was still just doing it's job. the 5.0 has problems just like any other engine, but this one wasn't giving in. Just traded it for a '24 F150 XLT 5.0. Looking for another 300,000... Thanks for posting, you've saved me a ton of aggravation over the years, and I'm sure for many others too!

My 2013 F-150 developed the same compression loss symptoms last spring. Research led me to learn about this exact issue. Symptoms crop up around 100,00 miles. I was at 105,000 when the misfires finally tripped the check engine light. (Idle was extremely rough since I bought the vehicle 4 years prior). One shop wanted to engine swap for $14,000, which I thought was a rip off. Another shop said they could tear it apart, send off to machine the heads and re-assemble with proper valves for just less than half that. Elected to do that, and it turned out extremely well. Never was a recall or announcement made about this problem from Ford, as it affects all 2011-2013 truck Coyotes engine, but forum posts confirm this affects 2014 models too. Like someone else in the comments said, these are ticking time bombs sadly.

[@mph5896]

$14k for an engine. What in the world😆

[@anthonygallegos3269]

@mph5896. It's not just for an engine. 14k is for the cost of engine plus parts and labor. In the automotive industry cheaper is almost always never the way to go. Thats how 800 dollar jobs turn into 8,000 dollar jobs further down the line.

[@Matt-i8r]

Ford may put the issue in a TSB for service techs,but don't look for any news release to the public! Add in the mileage when things crop up, and you see why Ford just ignores the issue! It's no longer a warranty repair at 100K unless you have an extended warranty! At this point, the dealer personnel try to blame it on your maintenance and cry not covered under warranty. Now they hope you go for a cash repair! Cha-Ching!

People are so dramatic. All engines will have a “common” failure point. Being something that occurs at a higher percentage rate. Thanks to the internet you have a few guys post on KZbin or a forum and act like the engine is a “ticking time bomb”. Not at all. This is a fantastic engine. This failure is rare. I saw it twice when I was a dealer tech and the fleet I work for now has a few hundred of these engine and we haven’t had this happen ever. We literally had never done a base engine repair on any Coyote engine until the phaser issue popped up on the newer trucks. Even still, though not minor, that is the only failures we have seen on any of them. By the way, I can search all that and run these reports through our fleet management software. As a side note. KZbin claims the 10R transmissions are garbage. All we have had done is software updates. These are all work trucks too. Often pulling trailers and almost always carrying cargo.

[@MustangGuru]

It’s even happening on some 2015-2017 mustangs as well. Not sure if it was a fluke but I had 2 valve springs break but got lucky the valves didn’t fall into the cylinder.

Machine shop thing is no joke. Few and far between for sure. We had 2 local ones near us (30 mile radius). One was in business for a long time, their lead guy ended up buying the business about 10 years ago from the original owner and now just closed this year and retired. The other shop is still open. He used to be one of the lead machinists for the other shop and went solo a couple years before the other place sold to their other employee. He's now a one or two man operation with the old wise guy from the place that closed helping him part time setting up racing engines.

[@ice44567]

Yeah, its becoming impossible to operate one anymore. Where's the business? Shops just quote used or reman engines now for anything because techs are overworked as it is. The labor $ isn't worth it, so that just leaves DIY project people or race car guys which not every area has enough of to feed a shop.

While the 5.0 is actually pretty good overall, the main issue is people just like to bandwagon whatever they purchased and justify it to anyone who will listen. A lot of times its old people or fudds who insist that "Turbo engines aren't reliable" just because its unfamiliar to them. They usually follow on Facebook just to see the ecoboost issues so they can talk smack on their friends that have one. That's why Brian gets so much hate when he talks about coyote issues, it shatters the reality that these people "chose correctly". Actual technicians know everything can and will break, and most powertrains have SOME flaw in this day and age that will affect some people. That's just life.

Survival bias. You'll see loads of comments usually about "my is the best vehicle ever made; today's vehicles are junk". No, they were all junk otherwise they would still be around in droves. Oldsmobile made hundreds of thousands of Cutlass cars in the 1970's. Best selling car in the world. When was the last time you've seen one? Chevy Cavalier they made over 225,000 in 1998 alone. Where are they today? In the junkyard crushed for scrap just like everything else.

[@Discretesignals]

@@TheRetarp that is because cars have improved since the 70's and many were totalled or rusted away is why many of them were scrapped. Sometimes things get old and worn out and it's not practical to dump a bunch of money into them, especially if parts are no longer made. Better mpg, better safety, less emissions, more features, and more power from newer models pretty much left the older cars in dust. Sure there are survivors, but they are mostly weekend drivers or show cars. I agree, there are some crappy designs out there on all makes and models.

Great info. Please do the generation comparison.

[@jowens1126]

I had this exact same problem on my 2013 f150. Same cylinder valves were eroded, compression dropped significantly and was having misfires at idle, no issue under load. 145k miles. I just had the engine replaced for $8k. It was worth it to me because the truck was in perfect condition otherwise. im now 60k miles into the replacement engine with no issues..

[@bojo8141]

Once again your skills are amazing, thanks for the info I've never seen that before. Great job.

[@derekmartinie2180]

Thanks brother I got a 06 4.6 L supercharged thank you for the info

[@SlyFox5.0]

It's amazing how many engines Ford has developed with catastrophic design flaws...and yet people still buy the garbage. Thank God Ford people have you

[@billk8780]

That is an expensive way to make pizza slicers! Great video as usual.

[@Bill_CBR]

I wonder if you could get an inspection camera/scope down inside via the sparkplug hole with a mirror attachment and see the face of the valves enough to see if they had that issue?

[@paulfiebke3909]

Don't let them get to you, keep up the good work.

[@gregalulis]

My 2014 5.0 was manufactured in December '14. Hopefully all of the defective valves were installed earlier in the year.

[@pauljanssen7594]

Yep there are two engines that have this intake valve problem I still remember the Ford 400 engine with bad valve springs.

[@Matt-i8r]

At least a set of valve springs on a 400 would be relatively simple to replace!

[@christuttle3980]

Anything mechanical can and will fail Thanks again for the great video Greetings from Vancouver Island British Columbia Canada 🇨🇦

[@samholdsworth420]

But soft valves? LOL!!!! What a joke

[@andrewslagle1974]

@@samholdsworth420 It had high millage so it needs a valve job big deal!

[@Failure_Is_An_Option]

Ferd is just better at it. Especially with their engineering silos. Losers use emojis.

[@Dusty_Bottoms_]

I love the knowledge and presentation, I just wish you'd take in some GM LT engines and dissect their problems.

[@maebnus46]

My brother has a 2013 f150 with the coyote eng. developed slight miss became worse. Got lucky tookto an excellent mechanic who diagnosed a low compression, removed head found a valve guide just coming apart. Then question was repair head or get New production 5L long block from Ford ?? Considering truck had 120k miles but was overall excellent condition . Went for newest production eng. New eng. installed excellent total price, very happy with truck and work. BW

[@ShersGarage]

I have seen that issue few times. My uncle had that happen in his truck around 180k. What a shame! Those are great trucks! I drive a second gen coyote, aside from intake runner problem, there are not many known issues.

[@hmrody]

Great video and thanks! Unfortunately, I have a 2013 F150 with a 5.0L Coyote engine 🥴. It is running well so far, but good to know if it starts to have a miss... Bummer...

[@JamesAgans]

Brian is as good as it gets if you own an F150. My 2004 5.4 Runs like a swiss watch because of him. 170k miles. I did a complete timing job at 153k miles preemptively after watching his 4 part series. I went even further and replaced everything up front + the oil pump while I was in there, plus all the roller followers, lash adjusters, and cam solenoids. Why Ford is having issues with valves is beyond me, as this technology has been well known for a very long time. Maybe they decided to go import? I have never run into a " sunken valve " issue in my life and I am 77 years old.

[@Jondog65]

Your lucky my motor was toast at 160,000 miles ! Started ticking and then engine light! The stock oil pump does not put enough oil into the Cam Journals. Had the motor swapped out for an upgraded motor from Power Train products. With a Melling high Volume oil pump. She runs like a champ now! 25,000 on new motor and running strong and Smooth! You may have saved yours just in time? I always changed the oil frequently by the way

[@JamesAgans]

@@Jondog65 I have always put in a pint of Marvel Mystery Oil on every oil change. My first job when I was only 12 was helping an old timer that worked on automatic transmissions. He swore by the stuff. So have I ever since, and I'm now 78. Frankly, when I opened up the front cover at 153k everything was pristine, including the roller followers. Brian is most definitely the best source for Ford owners in my opinion, and his videos are clear, concise, complete, absolutely correct, and very well done. My 2004 runs perfect because of him.

[@Jondog65]

​@@JamesAgansgood deal you caught yours in time, I didn't know anything about it before it was Too late. I also like Lucas oil stabilizer, definitely will add life to the engine.

[@thatrealba]

I have a boosted 2013. With 63k miles, I have to imagine that this is in my future. Guess I have to start budgeting for a gen 4 Coyote swap, WOOHOO!

[@jeffalvich9434]

I get the same thing Brian! There are people out there that are just mind washed that their engines are absolute perfection... I don't care which brand or what series you're looking at they all have strengths and weaknesses.... Some are just a whole lot better than others....... I especially shake my head when people badmouth the early gen V8's.....flatheads, Windsors, FE series...... When you look at the fuels and the oil and the filters and driving conditions back in those days, today's engines wouldn't last 50 percent of what they do today!

[@motormossvlogs1450]

Eh, idk i disagree. Look at 90% of the owners these days too. Half of “men” cant even change there own oil these days. Idk where ya live but look around you. Do your neighbors change there own oil? Majority, probably not. Let alone ever change the cars air filter.

[@44hawk28]

It appears like an inconsistent heat treat issue with the valves. If it were a mixture of metals that they were making the valves out of, all of the valves would be doing that or at least a greater percentage of them. Heat treat and or tempering Fred probably because they're being done in a mass, and the end valves were the one suffering the issue because they were getting a slightly different heat treat than the ones in the middle of the group, or vice versa. The first time I remember clearly running into an issue like this I was doing the bearing races on the Prototype M1 Abrams tank back in the early eighties. And I was finding some that actually had splits on the inside of the bearing races that had been outside and you it was very difficult to see the split with the oxide coating. But you can see it very clearly after I had done the inside grinding to a very tight specification. I remember that they came to me and told me that I was overheating them as I was cutting them and I opened a brand new box that had just come in and found three of them just in the top layer that had splits in them and handed them to him I said well then how do you explain the fact that they're already split when I get them. They were quenching them at far too high a temperature and it was causing them to actually erupt with splits on the inside and they weren't catching it. After I explained that to them they went back to the people who were making the original forgings.

[@MrTemplerage]

Wow! Never knew. Glad you're still making videos too.

[@andrewhill265]

My 2012 5.0 just passed 141k miles. Hopefully it’ll give me a few more healthy years!

[@andrews7911]

My 2012 5.0 just past 272k, its been my best F150. I had a 2005 prior but sold it after 180k to a guy at work and he drove it for another 100k.

[@detroit1018]

lol it will

[@amrmad6446]

Big shout out to Brian 🎉

[@briansbrain426]

Thanks!

[@marknaravas318]

I remember the endless valve seat problems on the DOHC 4.6 in the aggrevator in the early years. I had to tell customers that ford didn’t have a fix yet. For about a year

[@brianbaker2062]

I'm 160k miles I'm with 11 5.0 and she's still Cadillacin like new. Will be aware of this moving forward

[@canadianmarauder1923]

Thanks for the diagnosis Brian.

[@Aaron_Voltz]

This makes the 2nd valve issue I've heard of with Ford's valve supplier. The Broncos had bad valves also a few years ago.

[@josephvantreeck2989]

Thank you Brian

[@marcusbyler7837]

Been waiting for this video. Five years ago this problem became apparent with 1st gen 5.0 engines in used trucks out of Edmonton and Calgary. Perhaps the cold weather makes the problem worse? Anyway, three F150s in the family have had valve jobs. Its not that difficult or expensive to just fix it with new valves. MUCH cheaper than a new engine.

[@headspacehiker]

So the head you think isn't forming to the tuliped valves? If he's right and the valves are too soft then yeah maybe just new valves could be tried??

[@carlbruhn1772]

Fantastic camera work!!

[@tedjones-ho2zk]

Would really enjoy seeing all of the issues with each version of the 5.0. Just courious if the plasma bore liner will make the list of issues.

[@gr8tfoxes617]

Thanks for sharing this! Amazing the valves are failing like this.

[@Chris-ut6eq]

Have the gen4 coyote and very curious when we will start to see its issues. cylinder deactivation related or not. Thanks for taking the time to show the issue in detail.
