Ok, my dads truck does this really really bad. When the truck warms up it almost sounds like a diesel at times on his 05. He has brought it to Ford and when the truck was newer and they just told him the Ford 5.4 just sounds like than and not to worry about it. Do you know if a service TSB would still be in effect for his truck? or would i be something he would have to pay for now? Is it an extensive fix?

I find with my 09, if I am driving slow thr0ugh a parking lot, it will all of a sudden rev up (almost as if the truck goes into Neutral and clunk as it shifts. I had the 6speed tranny tsb for shifting done in July.

 

Wow! alot to respond to. The noise in the engine was a very loud knocking noise, almost like a rod knock. You could hear it coming through the exhaust from underneath the truck, no lose of power though from what my wife told me after I heard the knocking noise I didn't move it only to get it ready to load on the rollback. The mechanic thinks the wrist pin broke and damaged the cam phaser. The service manager told me it would be a new engine. Everything that touches oil will be replaced. I am still a die hard FORD man! and that ain't gonna change. Can't wait to get it back.

 

I will be waiting for the 5.0L 4V I have had enough of the 5.4

 

I would imagine the tsb is still active but, if the truck is out of it's warranty, you would foot the bill. Start and let the truck warm up, if you start to hear the ticking sound under 1k rpm, then it's most likely the cam phaser. There were times when it was pretty quiet, yet noticeable......not too many times when it was diesel loud. It's not really something that causes driveability issues though. To be honest, if it's not something you can take care of, I really wouldn't worry too much about it, it's not chewing anything up or anything, mainly just an annoying noise.

 

:Your dads truck is probably out of warranty so he is on his own also if he hasn't changed his plugs yet he better get it done I had mine done at a ford shop at 40K and they broke 7 of 8 but did get them all out without removing the heads, they have changed the plug design in oct.07 I believe was a design flaw from the start but ford would not own up to it.

 

My 04 was/is especially bad. Dealer told me recently the cost of cam phazer parts cut in half. Now much more affordable.

 

Thanks, he has had the plugs done too. I really am not sure why this cam phaser issue has not been diagnosed by ford dealers around here? Strange.

 

My 5.4 v3 2005 fx4 had 110k miles on it. I know it has a cam phaser noise that starts after the engine warms up. Truck runs just fine. Based on what is in a cam phaser, what is it that starts to make the noise. It seems to me that there is no danger of running a noisy cam phaser other than the engine sounding like a diesel.

 

Does anyone have the specific TSB# for this?

 

Pretty sure I'm into a cam phaser problem myself on a 09 F150 5.4 20,000 kms on it, when I am at a drive through I can hear the ticking echoing off the wall. Don't think I really should have this trouble with a brand new truck, I dealt with it on my last truck (01 Silverado, noisy lifters) and it gets extremely annoying. I will be making a appointment very soon to get mine checked out and following this thread very closely looking for the TSB# and how the rest of you are making out with this prob.

09-23-7 LOW FREQUENCY ENGINE KNOCKING NOISE AT HOT IDLE

Publication Date: November 12, 2009

FORD: 2009-2010 Expedition, F-150
LINCOLN: 2009-2010 Navigator


ISSUE:
Some 2009-2010 F150 vehicles equipped with a 4.6L 3V or 5.4L 3V engine, Expedition and Navigator vehicles may exhibit a low frequency knocking noise from the engine at hot idle only. The noise is predominately heard from the right front wheel well area and/or the right hand (RH) engine cam cover. This noise may be generated from the RH variable camshaft timing (VCT) phaser assembly. This procedure was created to diagnose the RH VCT phaser assembly.

ACTION:
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

The Integrated Diagnostic System (IDS) tests were developed specifically for the vehicles and Power Control Module (PCM) strategies for these vehicles.

Per Workshop Manual (WSM), Powertrain Controls and Emissions Diagnostics (PC/ED) and Scheduled Maintenance Guide, review customer service history for use of any aftermarket oil filters.

Check for possible diagnostic trouble codes (DTCs).
No DTCs present, proceed to Step 2.
If DTCs are present, discontinue with this procedure and refer to the PC/ED manual for diagnostics.
Engine must be at full operating temperature over 190 °F (88 °C) cylinder head temperature (CHT).
Connect IDS diagnostics tool and verify software version is at the latest level (63 or later required).
Begin a new vehicle session.
Open Tool Box selection.
Open Data Logger.
Select Powertrain Engine.
Select PCM Data Logger.
Clear the preselected items by clicking the eraser icon button.
Select variable cam timing desired angle number (VCT_DSD).
Go to live display and press the tick mark.
Make sure the parameter identification (PID) is highlighted with the dark lines above and below the data being displayed.
Press number symbol: (output state control mode) of the VCT_DSD number PID.
Press the Control Item Activate (finger on the button) icon to enable manual control of the PID.
Use the plus button to command to 4 degrees. (One click is equal to 1 degree) When commanding the advance, both banks will normally adjust.
If degrees will not advance, or there is an exclamation point after the PID selected, conditions are not being met. Check for possible VCT solenoid circuit faults, DTCs, incorrect engine timing, or a mechanically broken VCT phaser.
Listen carefully to the low frequency knock noise while commanding the VCT_DSD from 0 to 4 degrees.
If noise level is noticeably reduced as the VCT desired angle is commanded from 0 to 4 degrees, the noise source is the RH VCT phaser assembly. Proceed to Step 17.
If the low frequency knock noise is not noticeably reduced at 4 degrees, proceed to Step 16.
This step will create a 2nd unrelated noise, best described as a high pitch clatter or valve train type noise. This noise is to be expected during this step and does not indicate any component failure. Ignore the high pitch clatter noise and concentrate on listening for a noticeable reduction to the low frequency knock noise. Command VCT_DSD to 5 degrees while listening carefully to the low frequency knock noise. At the transition from 4 to 5 degrees, the high pitch clatter noise will begin, but should be ignored.
If the level of the low frequency knock noise is noticeably reduced as VCT_DSD reaches 5 degrees, the noise source is the RH VCT phaser. Proceed to Step 17.
If the level of the low frequency knock noise does not reduce noticeably as VCT_DSD reaches 5 degrees, stop and proceed to the WSM, section 303-00 for engine noise diagnostics.
Some higher frequency clatter is normal at or above the 5 degree advance. What is being pursued is for the level of the low frequency knock noise to be noticeably reduced when advanced from 4 to 5 degrees.

Due to normal engine dynamics, the VCT phaser knock noise is produced by the RH VCT phaser assembly. Replace only the RH VCT phaser assembly per WSM, Section 303-01 for the noise described in this procedure.

note where it says LOOK FOR HISTORY OF AFTERMARKET OIL FILTERS. dont bring your truck in with a Fram on it...im warning you!

 

My 05 had this issue, symptoms are just a knocking noise at idle, almost like someone is tapping a rhythm on your engine block with a rubber mallet. No drive-ability issues. Fixed under warranty around 1200 km's. One side, never came back.

 

It is unbelievable ford has not fixed this issue since 04, had both sides done on my 04 noise still comes and goes sure hope the 4V 5.0L has different cam phasers and a quieter engine:santa:

 

Wow! Is Ford trying to pin the blame on 3rd party oil filters? Cam phaser problem doesn't exist for those trucks with Motorcraft oil filters?
