: Ford 5.4L engine "tick"

I test drove a used (2000, 150K) F150 that had a slight "tick" to it. Owner said this is a common thing in the 5.4L engines.

I had the 4.6L and am aware of the sparkplug thread issues (happened twice on my '97), but it never had a tick. This sounds more like a lifter, or possibly even a slight exhaust noise, although it is possible it is a loose plug. It's not very loud, but it is noticeable.

Any other Ford owners have this issue? Is it something to be worried about? (I did not buy the truck).

My guess would be the exhaust manifold bolts. Had to replace both sides on my 97 with 4.6 as it was making the same "tick" sound. Fairly costly if the bolts are actually broken off as it would take btwn 3-4 hrs labour each side.

Warped exhaust manifold, they don't have gaskets. Mine warped and I had it fixed. After the spark plus, manifold and rear brakes (2005) I changed brands. At that time ford was trying to get horse power with high RPMS.

Bad video but I will bet this is the problem. Cam Phaser.

Sounds like the cam phaser. My 2004 is in the shop now having a new engine installed. Same problem.

It didn't really sound like that...hard to describe, but it sounded a bit more "crisp" or pronounced.

I am tending to lean toward's Paul's manifold explanation. That's the area where I thought the sound was coming from.

It's the exhaust manifold... I just had the second one replaced this week.
It more pronounced when the engine is cold and under a load?

Good choice to let this dog alone.

Those engines (early 2000's 5.4 L) have gremlins and you could spend thousands of $$ and still have problems. A good buddy HAD one, F150, about the same age and replaced, on his and Ford's mechanics advice the following: Intake manifold, all plugs/ignition coils, lifters, exhaust manifolds, catalytic converter, and a few other things. Never fixed the problem and he finally traded in for another Ford (why, I'm not sure?).

His would "tick", knock (sounded like lifter knock), run rough, bad mileage. Compression checked good, cylinders were inspected- good. Just a money pit for a year or so till he got sick of throwing good money after bad.

i have a 04 150 5.4 (newer style), runs great does everything it should has 114k on it. When idleing it sounds like a very quiet diesel I think its the lifters, but the noice stops as soon as you give it gas at all.

When that quite diesel sound starts getting louder trouble is on the horizon.

I have the same...04 5.4L 3v w/135k miles. RH Cam Phaser has been softly ticking for the last 2 years. Seems better in very cold temperatures. Ford dealership mechanics all tell me that I don't need to worry about it unless it gets considerably louder. Going in for induction service tomorrow so I can start thinking about plugs. Mileage has been getting worse so I suspect plugs getting bad...after all it's got 135000 miles. Still runs very well though.

Thump,
If you are looking at a used vehicle and the vehicle has engine noise that you don't like - do the simple thing.

Drop that vehicle out of consideration and keep looking.

There are hundreds of thousands of used vehicles on the market who's engine do not make any unusual noises.
So, continue the search until you find one of them.

Forget about whether this vehicle is less money or something else.
There is likely a good reason for the $$ being asked for the vehicle.

Life is too short to worry about inheriting other folks problems.

There are plenty of good used vehicles on the market with quiet engines and sound drive trains to consider one that doesn't have both.

The owner is right. I had a 2000 F-150 4x4 and it did the same thing. I didn't have any issues with the motor. I sold the truck with 113K if I remember correctly.

mine is the same. My truck has been running great but when its started cold it sounds like ****....No rpm changing, milage is the same as always, still pulls great. I am assuming manifold and I will just ignore it as my 05 F150 XL isnt worth much financially... My wife is prego and my regualr cab truck wont cut it much longer, so a new truck will be in my future in the next year or two...

a 2000 doesnt have cam phasers. 2004 through 2006 have the noisy cam phasers.

Exhaust manifolds were notorious on these trucks, they created a "clicking" sound.

Work for a Ford dealer for many years, no cam phasers on that model. I drive a 2001 F-150 with the 5.4 that has a noise as you are discribing. Mine is the bottom of the piston skirt tapping the cylinder wall, I bought it that way, knew about it, and have over 50 thousand on it since. Just one of those things, never seen one puke because of it. If you make sure it is full of oil to the top of the hashes on the dipstick it will be less pronounced. Could also be exhaust manifold, but like someone said, it will be much louder cold and diminish from there and if you look at the manifold, it will probably have a stud or two missing. Hope this helps

Mine was the 2008 with 3 valves and it was the manifold. I had them replaced by Ford and it went away. That motor had 158,000miles when I let it go. Cam phasers? That never came up in my issue.
