Beau Granbois: It might be the cam phasers. The locking pin in the phasers locks the vct
at base timing and unlocks when oil pressure builds up and activates the
vct, which is at about 1200 rpm. You could still hear the tick or chatter
at 1200 but I couldn't hear it at 1500.

SuperDonkeylips: Vacuum line is loose on your heater core line that will make your engine
run ruff also
Brute Triton: man i need sex
Danny McCarthy: lined all our 5.4s up at work they all ticked some got it fixed some
didn't. it didn't seem to affect the truck they've been running for over
200,000 miles with the tick. the ones who got it fixed ran the same.
personally i think the tick it just something they do and i don't think it
affects the engine. I've talked to many people they all have different
components that they claim fixed the tick so i really don't think its a big
1puld: Its true they r JUNK I had my phasers done once under waruanty at 40000
and friend (great wrench) and I did at 60000 its a shame 2 months after fix
adjuster gets lose that can also tick. Bare with me but ONCE U FIX PHASERS
NEVER USE 5w 20 AGAIN. After the engine gets past 30000 to 40000 5w 20 is
to thin . There is not enough oil pressure on the top of the engine for
phasers to advanced and retard properly they scratch bind and break. Right
after 2nd fix I run 10w 30 in winter and 10w 40 in summer might not get
the best mpg but no more phaser issue. And the rattling at start up
tenisoners had that problem too. THEY leak but cheap to fix if u do
Ryan Hughes: The 5.4 is not engineered properly anyone with knocks or ticks or a gas
diesel truck needs a new engine. Ford replaced mine at 80 k under warranty.
The cam profile needs upgrading as well as some extra machining in the
block. If they replace phasers timing chain ect. It will fail again. If
ford tells you it needs new phasers slap them good and say you want a new
engine to replace the defecto one! Mine was a f150 5.4 2009 screw.
dioslen rondon: tekjanson, how much did you pay for both phasers to be replaced and was
this a complete kit with chain etc or just the phasers? sorry i have the
same issue and my truck is exactly like yours now with 155,000 miles on
it...your help is greatly appriciated!
Gale Sams: i HAVE BEN Adiesel MECHANIC FOR 40 YRS. TRY USEING rOTELLA 15- 40 i HAD ALL
THE PROBLEMS yOURS DID.
TC Thompson: Shouda caused a "check engine" light come on as well. There's a alignment
pin that correctly times the cam timer ass'y to the cam that shears causing
the problem. Even replacing the cam gear ass'y will work for awhile, but
it's gonna do it again,guarenteed!
benscd1: I have the same problem on my 05 F150 took it to the dealer 3 times they
replaced phasers timing chains and injectors they also did my oil change
twice I did the third one they blamed me for putting a after market oil
filter they said they found pieces of the oil filter on the cam and that's
what was causing the problem truck been making noise since the first time I
took it in they replaced the rocker arms still hear the tapping noise they
told me to take it to another dealer now Champion Ford
TC Thompson: I maintain a 475 vehicle fleet that has several of these 5.4's in f-150's
as well as the f-450's w/ 6.0L diesels. These damn things are in our shop
more than any of our oldest G.M.'s! We don't go a week without at least ONE
Ford come in with problems! Mike Rowe, I sure hope you get paid WELL to be
thier spokesman! Biggest P.O.S. ever made!! Henry should be spinning in his
Eddie Linhares: I got piston slap on my 2000, no call back and they fixed it in 2001 ford
found the defect but never took care of their clients, as for the newer
models all they did was add ten pounds of metal in the right areas to mask
the noises of their so called tough engines.
rumerboyz: Oh, forgot to let you know my truck is a F250 5.4 Is your truck a Superduty?
MrJtmulanax: ive been running 5w20 in my 07 f150 5.4 since the day it was new!! Never
been over 4500 miles on an oil change and always use motorcraft "ford" oem
filter! But however my truck still sounds like a peanut thrasher when it
warms up!! only 30k miles.
rumerboyz: Thanks for the info man! I will try that.
rumerboyz: My truck burns about 1/2 quart also. Does your truck have that tapping at
start up and under hard acceralation? Do you use Motorcraft 5w-20 oil?
rumerboyz: Are you happy with the 5.4 engine? I'm still trying to figure out the
tapping coming from my passenger side while on the gas. Doesn't make the
sound in park. I have heard the same noise on a F250 and F150.
Filmaker25: It almost sounds like engine tapping. Hmm, I'm wondering if maybe my engine
isn't really knocking afterall, my engine sounds very similiar to this in
the monring , when it's cold.
tekjanson: Nate, The oil pressure is a much bigger issue. I would focus on that. I
changed my cam phasers and the truck idles smoother, and the rattling when
I first start it, stopped. The engine is still noisy, just not as noisy
(these are noisy engines). Mine got progressively worse, and the engine was
sounding more like a diesel. You need to find out if that oil pressure is
just an indication problem, or is it for real. That can destroy the engine.
TheEprom101: VTC solenoids are gummed up.
Gale Sams: hey barrett
tubesteak0u812: @G2203V54 oil galleries is that where they hang all the oil paintings? I
have never been to an oil gallery would love to see one, also the oil price
is no more than any other name brand oil
STEPHEN PARKER: @LPcustom76 I just purchased a 100k f150 5.4.. Same bad knock at low oil
startup... and at stopped situations where I power up... Not a healthy
sound.... Dealer said.,,, Service bullletin out about clogged oil port from
bad oil filters.... I call BS. Thats Fords excuse for a recall must. These
phasers are defective. Look at all the people on the net trying to find out
a fix... over 100k searching for the holy grail.... for the 5.4 3v motor.
Wolvee: No, this is only a 3v problem. Your 03 4.6 is a 2v.
rumerboyz: thanks for the info!
flaresama: Sounds like mine, Just bought it used, had 140k on it. 5 months later after
learning about the cam phaser issue, I lost two cylinders and now my truck
is sitting in front of my house with several $5-8k repair estimates.
Kendrick Evans: Can anybody tell me if this problem occurs in the 4.6 trition as well. I
have a 2003 Ford Expedition 4.6L and it makes a engine rattle noise
SOMETIMES during start up...I'm wondering if that could be the issue
badderthanyou: I don't agree. So many cam phasers are bad with people ONLY using Moto 5w20
Semi Synth. The 5w20 was used for CAFE/mpg reductions that Ford needed, not
in the engineering of the mod motor. Same motor in all other countries
other than Canada specs 5w30 or 10w30 and they don't have the number of cam
phaser issues we do.
Randolo88: Love ford! Have a 2010 at 87,000 phasers went. They put a whole new engine
in under warranty over 12 grand!! All free ford Canada best to deal wiyh
Gale Sams: Yes i do use shell Rottela in my super duty 15-40 I did change 1 VCT on
right bank.still runs good , I use nothing but Motor craft filters.
azascan: I do freak face....the 04 05 years are epidemic with this problem.
tekjanson: My truck is an F250 5.4 three valve, and this is a well known issue with
this engine. I have had the cam phasors replaced and the engine doesn't
sound much better, but the idle is a lot smoother. The rpm's are not
jumping plus or minus 500 rpm when I am at a red light. Have a Ford Dealer
replace your plugs at 60,000 also. The plugs might break in the head
otherwise (another poor design), and they have a tool for removing them if
C21GoldCastle: The vacuum line was disconnected from the heater control valve. ?? Did you
tekjanson: @G2203V54 More good info. Thanks. I'm only familiar with the 5.4 with
variable timing, and the Honda's VTEC. Both require a light wt synth oil
because they have little passages that the oil has to pass through in order
to adjust the cam timing on the fly. I wonder if any one is doing it
differently?. Anyway, thanks again.
tekjanson: The burning oil shouldn't have anything to do with the phasers. My
experience is that the phasers tap when idling. I saw another video where a
guy's phasers would rattle/tap when he accelerated. The phasers are at the
front of the engine. They are round and sit in the round part of the valve
cover. Have someone step on the gas while you listen to see if the noise is
from the front part of the engine on the passenger side bank. This could be
Brennan Barrett: Its a gas engine... XD known issue...
D4x4Bronc: no 5w20 only
Dade Dooley: what oil should i use for my 2004 ford f150 with a 5.4L
myHome109: I noticed you still have the old style radiator cap, those have been known
to fail at 0-4 psi allowing the coolant to boil out at 230F and never
signalling an overheated condition. This can leave your heads dry, cooking
the oil into sludge damaging the sensitive parts, phasers, lifters,
hydraulic cam chain tensioner, etc... Change out the $12 radiator cap with
a new FORD design rated at 16psi.
FordsAreSick11: is it a 05? my dad had a problem with the cams and we fixed it and it runs
giantj6ft7: All 04-09 f150's are riddled with problems from the IWE,solenoids,plugs,
and vacuum lines...anyone want to buy mine.
tekjanson: Really?? You put Rotella 15-40 oil into a 5.4 gas engine? This is a gas
engine that we are talking about. If that fixed your issue, that's amazing
HannahxoAbbi: Is it possible that it can be a exhaust manifold leak?
myHome109: By the way, have you ever used a plastic pipe and put it next to your ear
and against the engine? It is a very accurate method in determining where
the sound is coming from. My noise was coming from the injectors because
the gas evap can line was broken, forcing the injectors to work over time,
fouling the plugs, causing knocking and idle wobble. My fix was new evap
can line, flush out the injector, decarbon, new plug and oil change. And it
was loud knocks, but not phasers!
TheTerminator310: I'm really happy with the 5.4. Had mine for nearly 4 years with great
service. Mine taps too, but only when warmed up and if the engine RPMs are
anywhere between 800-1,200 RPMs. That is the VCT solenoids cycling oil
pressure to the cam phasers when it's warmed up. If that is when the sound
occurs on yours, then that's what it is doing. Very common and normal noise.
LPcustom76: @G2203V54 when you say "run a engine carbon cleaner thru it" do you mean in
the old engine oil?
THEMASTEROFYOU2000: @emyreth07 read my above reply. Just use something like catrol gt 5w-20,
always, and the correct filter, very important. the only additive I have
ever (in 35yrs) found to really work is the Dura-lube, and I buy it at our
local general discount store by the 12-pack case for like 32$, and use the
small aditive only size, not the larger 32 ounce (with 20-40 oil). I ahve
been around the suto scene for over 38 years, this is the only legitimate
additive I have ever found and I use it.
Odstbone39: Are these problems only common on the 04-08 model f150 ?
rumerboyz: My noise is tapping when it's around 2,000-3,500 RPMs I'm trying to get
someone to figure it out. Most tell me that my 5.4 is a good engine that
will go 200,000 miles. Thanks for the info!
