the motor on my son's 2004 Ford pickup, 5.4 liter motor has started making a ticking noise after it's warmed up,
94,000 miles, truck is in excellent condition other than this minor ticking noise.

you can hear the noise at idle, but not when driving down the road.

he uses Ford oil filters and Ford oil 5W20.

most of you guys that ever owned a truck this model have probably traded them off for newer trucks by now.

but, do you ever remember having a motor tick with your 5.4 liter Ford motor.

if so, what is the cure, is it a valve, injector, it does not miss, so I would not think it was a plug loose.


I really do not know what to tell him to do, as he likes to have his vehicles in top condition.
he only drives the truck approximately 8,000 per year. has the oil changed at 6 months or 4,000 mile intervals.

reason I ask here, he has ask the dealership, local repair shop and one or two others, who should know about this model motor, has gotten a different answer from each;

bad plugs, loose or worn timing chain, flywheel loose, coil packs bad,
etc:
Thanks for any suggestions,

I suggested changing the oil, use Ford filter and 5w20 oil, but replace one qt of oil, takes 7 qts (I think) with one quart of Lucas oil stabilizer,
might be worth a try, before letting some one tear into this motor,

again, any suggestions are appreciated!

That 5.4 should be a 2 valve per cylinder engine, so NO cam phasors to worry about.

As far as the 5.4 2V or even 3V ticking, yes, they ALL can do that and not have a problem. Some are more loud than others and often only when extremely cold..

I have one with just under 200,000 miles and it had a slight tick when cold that would go away when warmed up.

BUT, even so, with a 2004 there ARE a couple of things that NEED to be checked.

Number one is the spark plugs will tick when slightly loose.. If loose you ARE risking having a plug(s) EJECT causing a lot of expensive repairs (timesert or head replacement).

Do not rely on the dealership to check the plugs.. I nearly found out that dealer mechanics do not know what a TORQUE WRENCH is the hard way.

Had my 2006 in for plug replacement, shortly after they replaced the plugs I started smelling raw fuel in the cab (but only when backing up or stopping at stop lights)..

Back to the dealership multiple times and each time they came back with no problem found?

Finally I pulled the COPS one at a time I discovered ALL the plugs were loose.. One plug took a 1/2 turn by hand before hitting the seat!

Those plugs NEED to be TORQUED to proper specs for that engine year.

Secondly is a slight tick can be caused by a broken or cracked exhaust manifold or manifold bolts.. So far I have not had that on any of my 5.4s.. Sounds like it could be a royal pain to fix.

As far as dumping stuff like Lucus or other additives, don't.. They are nothing more than expensive junk and will not "fix" anything..

All good info but small correction. 2004 was actually the first year for the 3 valve in the F150.

for 2004, they also corrected the spark plug spitting problem. Only problem now. You can't get them out. Ask me how I know? Ford sent out a bulletin saying to change them at 60,000. they would come out easier. NOPE. Will not come out. Did all the soaking thing, and followed Fords instructions. they are still in there. It don't miss, and runs perfect. so I'm leaving them in.

Now mine clicks for a split second on morning start up. Until the oil gets to the top of the engine. Quiet after that. Or I guess it is. Can't hear a little tick with the Magnaflow purring.
