Engine Knock! help!

I have an 04 F150 Lariat with the 5.4. I get alot of noise out of the top of the motor. I hear lots of stories of sludge issues, is that the problem or do I need to have the motor gone through? the knock is not horrible but when the motor is warm the noise is pretty aparent!
Thanks
Jay

I just got done fixing a click/knock off of an 05 v8 150, turned out to be an exhaust leak off of the manifold, you can try checking for that too.

Did you read the thread, 'Phaser tick fix without replacing phasers', by Chris Carter? on this page?
