Top 7 Worst Ford Engines That Won't Last

[@aaronburratwood.6957]

The four cam 4.6 litre engines were some of my favorite for sound and performance. Coupled with a T5, it’s a good time.

[@randymcmanus8691]

Absolutely 💯 I have 2 Lincoln Mark VIII's a 97 and 98 with the 4.6l 32v and they are great cars, I removed the Cats and ran straight pipes back to Flowmaster Outlaws and they sound nasty and pissed off the Mark VIII were the first with the "Cobra" engine in 93' originally called Intech and later adopted by the mustang ,one of the best Ford engines ever built great cars and very fun .

[@Sailor376also]

You have errors in your information,, serious errors. The small Triton was,is the 4.6 liter V8 a truly excellent engine. Low speed, excellent mpg, 300 thousand mile engine if you change to oil and keep up the maintenance. The 4.2 liter for the years you mention is a V6 and in the 2000 to 2009 the 4.2 liter 6 is also an excellent long life engine. In BOTH cases, these are not the 4 valve race car Mustang versions These are the simple small 8 and 6. You want to rev them high and make them scream,,, they are not built for that. You want to put a ton in the bed of the half ton truck and drive from Albany to LA, and back at 70mph,, that is the right truck and engine. I stopped at 4:14 with that much bad info on engines that I know and have owned,, not worth my time to watch any more.

[@scottyellis3442]

I agree with you, I stopped at 4:28 myself. I have a 4.6 V8 with 302,000 miles on it & still running strong, "2005 Crown Victoria P71" I also have a 2008 F150 that has the 4.2 V6 with a 5 speed manual that has well over 200,000 miles on it, & it stays loaded with tools while pulling a 8X12 trailer.

[@will5150]

this is a scam A.I. channel.

[@davidgardner-r8l]

well i been ford tech for 39 years and i agree with some of these engine problems but i also disagree with a lot of these engines mentioned..

[@mack1ford]

The power stroke was not made by ford neither was the7.3 and 6.9 liter diesels. They were built by international under contract for ford.

[@bennygreene1421]

Hard to beat a 4.6 Others are the straight 6 which were tough

[@rexdaugherty1987]

To be fair to the 6.0 and 6.4 powerstroke's they were built by Navi -Star International.and sourced out to Ford for the Super Duty trucks

[@tombell5879]

Sounds like he just doesn't like Ford engines period.

[@jerryware5749]

I had a 97 F150 with the 4.2 V6. I don't think it could spin a tire in an oil slick. The second time the intake gasket failed, I traded it in with only 122K on it. Bad engine.

[@guitarguy442766]

This is an awful video. It’s loaded with countless errors and false information stemming from laziness and lack of research.

[@carlfowler1996]

-What about the engine the had an internal water pump? Any leak went directly in to the oil.

[@abc55206]

This is so full of bad information. 4.2 V8 was not used in those years. Are you talking the V6 or 4.6 V8? Also the 5.4 was dead solid unless specifically talking about the 3 valve, which you did not

[@turbovolvos40]

I disagree with the 3.5 ecoboost assessment. Sure, it had some problems, but no where near enough to make a worst engines list. Even Toyota, famous for reliable engines has a much worse engine than the 3.5 ecoboost in their new Tundra trucks, with engine failures becoming common.

[@turbovolvos40]

He literally just made a video that contradicts what he said about the 3.5. He put the "ecoboost family" on his video of top 5 most reliable Ford engines. kzbin.info/www/bejne/iaLUhI15l7uUfNUsi=_nwcTLp0eKGAuN5t

[@aaronburratwood.6957]

A few months back I traded a ‘92 mustang roller for an ‘84 SVO that was parked next to a barn back in 2001. It’s rough but it’s all there and I only paid $300 for the roller close to 10 years ago. I bought five foxbodys years back, I never paid more than $1000 each and I just put them aside thinking they’d increase in value. I particularly have a thing for t-top cars.

[@7c8f9x]

THE ENGINE IN MY 63 1/2 FORD RANCHERO IS STILL GOING STRONG EITHER 107K OR 207K MILES IN IT, RUNS VERY WELL,,NEVER BEEN APART YET, 260 V8, EDELBROCK 289 PERFORMER INTAKE, 600 CFM EDELBROCK 4 BARREL, DUALS, FLOWMASTERS,, JUST KEEPS GOING AND GOING, NONE OF THE PROBLEMS MENTIONED IN THE VIDEO, FORD DID BUILD GOOD ENGINES AT 1 TIME.

[@steverekstad322]

I have a 5.4L 3 valve with over 250k on it, and still runs great. 2008 Expedition.

[@mattnull7090]

I had a 4.2 liter V6 and it was a great engine

[@kennethburton9165]

A lot of the video clips were taken from other KZbin channels, what a lazy way to make a video, thumbs down.

[@savonshegog99]

Super lazy didn’t even bother to match proper model years of vehicles with the engine

[@MrAnimefox]

Super lazy when he shows a bunch of different engines while talking about a different engine entirely.

[@cjespers]

It's obvious who ever created this video was a keyboard jockey. What a joke. The 3.8 Essex had some issues, yes but it was LOT better than the 4.0 sohc. Never seen such a poorly designed timing chain (s) setup.

[@RudyAckerman-u3z]

The 4.2 was NOT a V8. And the 3.8 was Not an Essex.

[@mechanic1955.]

Have the 3.5 eco boost have had no problems only will have problems when you don't change the oil regularly don't go 10,000 miles change at 5,000 miles.

[@josephmclennan1229]

I have a econoline with 268.000 miles ,5.4 , 1998 2 valve ,. I have blown 3 plugs . but overall a good engine . The 3 valve 5.4 was a piece of crap 2004 - 2008 . I actually blame government for change fuel; mileage standards and pollution controls . They have to reengineer their engines in a hurry , and make them more complex , more problems.

[@Mike-w5d]

I have a 08 expedition 5.4 3 valve, with the newer head with a normal spark plugs, change oil and filter every 3500,, has 267000 And runs great maintenance

[@MrAnimefox]

You're out of date and not fully right. The first gen 3.5L ecoboost was known for those problems, but it was the cam phasers that caused the problems. The second gen solved at least the carbon build up in the intake by having it has a multi port injection system. You forgot about the 1.0L ecoboost. That's been having issues for a while now with no solution insight.

[@ronsmith7739]

I think a major problem the engines are too compact making the entire size is too small.

[@1fast10r]

4.6 v8 not 4.2.

[@aaronburratwood.6957]

Yeah, I caught that too.

[@yanmeyer8243]

That is exactly what I was thinking 4.6 ford never made a 4.2

[@1fast10r]

@yanmeyer8243 well they actually did but it was a v6

[@RandyRoach-r2d]

All the negative talk about 5.4 3v engines is silly. Been blown way out of proportion. We have 3. All with over 175,000 miles. One with 240,000. Never had an issue with any of them. Change my own plugs. Never had any issues. Mechanics are crybabies any time they have to actually earn their money.

[@rojorios319]

I have a 06 f150 king ranch buy in september 05 still going like new nothing mayor...i change my oil evrey 3000 replase plugs at 100000 and its almost 200000 miles

[@dannyhocutt8490]

Notice all these problem ford have (mentioned) are lack of Ford keeping up with engineering!

[@georgegrill3262]

6.0 wasn't a ford engineering problem, that was an international engine.

[@georgegrill3262]

6.4 international took another shot,still missed the mark! Ford got sick of the bad engineering, so developed 6.7, on there own.

[@andrewb9708]

It actually was a Ford engineering problem. Ford used Motorcraft Gold Coolant which is the source of most 6.0 issues. The International VT365 didn't have as many issues, but still had injector problems.

[@mrdluna84]

All I got from this video is- EPA made Ford struggle to keep up with their demands and Ford engines are junk if you don't do proper maintenance... 6.4 is junk. But with proper maintenance the 6.0 is a great engine. The 5.4 was a very reliable engine when properly maintained which includes using a torque wrench so you don't strip the spark plugs. Trash video spreading false and weak claims.

[@patstevens2959]

Ford Engineering,as per usual!!!

[@Jody-kt9ev]

At time 9.49 there is a picture of a bunch of non-Ford cars. Why is this in a video about bad Ford engines? I own a Nissan Frontier (left center picture) and its non-turbocharged, naturally aspirated engine has been fine for 105,000 miles.

[@tylerdurden6208]

Good info but your irritating and interrupting music track drove me away.

[@rafdecc]

Thank you I wasn't going to listen to your video I thought I knew it all about the Fords but now I'm a Chevy general motors guy Pontiac my dad had Pontiacs Buicks Chrysler and I had Chevy suburban 5.7 245,000 me on a real gem of an engine after hearing this with no way would I buy a Ford I was looking at a 2008 guy wants $18,000 for it and did the EGR and all that other crap but you know what it's still a piece of s*** so I'm buying that I wrote in a 2006 Duramax with the Allison transmission could not believe it the power the quietness the smoothness of the shifting it's got Duramax has them all beat

[@jimmywilkinson9190]

Found Oil Right Der

[@gregoryplummer-l9l]

Ford should have never dropped the 7.3

[@allanrheaume5549]

That 7.3 was a great engine though it was made by International Navistar as was the 6.0 and 6.4 mentioned in this video.

[@bobsmoot8454]

Quality, job 1

[@getdusty1]

Why in the world people keep buying Ford's is way beyond my realm of thinking!!! There are WAY better options, like Honda's or Toyota's. Were Ford's mechanical engineers students who flunked out of university???

[@JamesBlume-u4i]

What happened here Ford?

[@peterdarr383]

At least FORD circled the problem !

[@chrisbaran4473]

I find this whole video crock of shit, it was a 4.6 not a 4.2 as stated by many below the two engines offered in them years were the 5.4 and 4.6. Also your showing the wrong year vehicles while talking about the engines that were in them. Showing a 1993 clypso green foxbody while talking about a 3.8 v6 is just plain stupid becuse that turd motor wasent even available until 1994 in the sn 95 body style. And the biggest problem with them was in the super coupe thunderbird becuse boost pressure and expansion rates don't mix. Most factory 3.8 non supercharged were just fine though they lack performance. Moving foward the later year 4.6 and 5.4 with the p.i. or performance improvement had issues with the cheap ass plastic intakes litteraly cracking.keep in mind with anything if it isn't maintained the results will show.

[@pathunter7003]

This author needs to change the name of Tire Marks to Skid Marks, it’s more appropriate. I’m sure he will delete this comment

[@oscaracme]

They had problems not "issues". Learn the proper meaning of words.

[@alxf66]

Pretty much a garbage video that feels and sounds like AI. Thumbs down.

[@RichardSevcech-hz3xu]

You GM people

[@owenhill-vf7ko]

Plagiarism 🤡

[@yougoof]

There's no 4.2 v8. The 4.2 was a v6.

[@robertmcnair983]

Older gas motors big block so good get gas motor diesel is junk

[@robertmcnair983]

Just get Toyota I got one

[@allanrheaume5549]

The new Tundra V-6's are having their fair share of problems lately.
