This is your second useless and unproductive post in this thread. Clearly you have nothing better to do. Grow up

I would take it to another dealership, or being out of warranty now, I would take it to a trusted mechanic. Every vehicle has an issue in one area or another, however I will admit that these 3V engines were designed improperly. The lower end of these engines are very durable and don't necessarily need to be replaced. If the engine isn't very sludged then replace the cam phasers, timing chain, guides, and tensioners. $1500 for a top end rebuild beats a few grand for a re manufactured engine.

This dealer told me bottom end wasn't issue but heads and everything in them had to go. If $1,500 would solve the problem I'd happily pay it I'm just concerned that it won't. I e read several posts in here it either didn't fix the problem or only temporarily fixed the problem that's why I'm kind of believing the dealer. I will approach another shop to see how much they'll charge to swap everything out.

If you do have it done, do everything at once. I think most people have reoccurring cam phaser issues because they only replace the phasers and not the components that work along with them.

Dude take it to a legit shop for diagnosis, there is so many things that can make those noise an symptoms, it could be anything from timing chains to vct solenoids or phasers or lash adjusters. But get away from dumbass dealers, sure an engine noise could be fixed by replacing an engine but that doesn't mean it's the best way. It sounds like phaser noise to me, get the livernois lockouts ($60) and then get a tuner an run livernois' tune for them, you'll lose about 15 hp with the lockouts because you lose the vct but you'll never have issues again. Seriously though get away from that dealership, dealerships are honestly about the worst place to diagnose a problem. If their is any race shops or mustang places around you go to one of them, they will have worked on plenty of mod motors before. I've been through several mod motors and seriously go to a good shop for diagnosis first.

Does your motor sound like this video?

I also thought about the 07 & 08 because of the head design change but don't know if that change only addressed the spark plug issue or if it also improved lubrication.
I know how you feel bro. My 04 FX4 was with 105k miles was starting to nickel and dime the hell out of me. I seemed like one thing after another from spark plug issue , constant rough idle, loud ticking, tranny slipping so I cut bait and got a 4.6. Less power but I'm at ease knowing its smooth and has been trouble free.

I don't think the newer 07 & 08 5.4 are any better. My friend just sold his 08 and it had the notorious tick and rough idle. On a bright note, spark plug change was no prob for him, he had 120k miles. Your truck is a 3valve so from what I understand you have to stay with a 3V motor, swapping the older 2V 5.4 would be too difficult. For me, I have a 2v 4.6 so doing the 5.4 2v swap would be easy from what I've read.

2010 models may be better, I looked at one with the 5.4 and 6spd. I almost traded my truck for one but I don't want any payments. The motor was smooth, tick free and good power with the 6spd.

Good luck.

These people telling you that you need a new engine are playing you for a sucker. Consider this...how much will it cost you to rebuild the front of that 5.4? Compare that to the cost of a new, or newer, Ram or Chevy. If you're swimming in cash, then go nuts...if not, then just replace the noisy parts of that engine and be done with it.

Take it to another mechanic...I consider most dealerships nothing more than rip off shops. I know a lot about vehicles, and I've busted them red handed trying to oversell me on some bull**** when I went in for a coupon oil change or alignment. I drive an '04, and it's like the day I bought it, no issues at all.

If by chance, it started to suddenly make a racket, I'd get it fixed...even if it cost me five grand. I will not buy a new truck until they get 25 mpg, real world. Do the math, dude.

primal has been following one of my threads ...

https://www.f150forum.com/f4/2005-f1...20816/index11/

Feel free to read all 11 pages, but the 11th page tells the cliff-notes tale about this 11th generation piece of trash (what an interesting coincidence). I really wanted to love this truck, but I wish I could take a friggin' acetylene torch to it. Oh how gratifying that would be.

The fact is the 5.4L 3V (NOT the 2V) might just be the crappiest POS that Ford ever built. I just replaced all of my timing components ... phasers, chains, guides, tensioners ....ev-er-ree-thing! And yes ... FORD OEM PARTS ... not Cloyes with their crappy tensioner seals or Dorman with their defective phasers.

I have less than 300 miles and it has been soooooo quiet. Then today on my way home from work I hear it...the slight hint of a low-tone tick (soon to be a clunk again, I am sure) and I am pretty sure I can hear at least one of the chains during acceleration. I am also pretty sure that when I abruptly let off the gas ... say doing around 30-40mph ... I can hear a slack-chain rattle as the motor trims down.

And yes, I have adequate oil pressure. Admittedly, it does get down around 23-24 PSI, according to the $30 Oil PSI gauge I bought ... that's when the truck is at max temp and I am sitting in Phoenix traffic at 105F+ outside (in drive, foot-on-brake). Full operating temp, idle with the tranny in park and I have 28-30 PSI all day long. Anything over 1200 RPM and my PSI is 60+ ... all the way to 70-72 PSI at WOT.

Sorry folks ... call me a whiner ... tell me to buy lockouts ... but I can't believe Ford produced such a GD piece of
