I got a question for this, my truck runs great but there is some phaser noise that seems normal. Question is when Im in gear, anything except N or P under light acceleration there is a horrible clanking, what do think. Replace the chains, tensioners, and guides only? Like I said truck runs like its new just makes horrid noise under light acceleration only in gear

all right guys could use some input finally listened to my truck when it is ticking, does not tick on start up but ticks pretty loud at idle warmed up and then goes away above 1200 RPMs, the ticking is defiantly louder on drivers side, i going to do this soon, question would you just do it all when it is torn apart or just what is needed thanks

Here is a TSB from Ford:
21574 4.6L 3V/ 5.4L 3V ENGINE TICK/RATTLE FROM VCT 800-1200 RPM - DO NOT ATTEMPT SERVICE
2009-2010 F-150 WITH 4.6L 3V, 2005-2010 F150 WITH 5.4L 3V,2005-2010 MUSTANG WITH 4,6L 3V, 2005-2010 F250, F350 WITH 5.4L3V, 2006-2010 EXPLORER/MOUNTAINEER WITH 4.6L 3V ENGINE, 2007-2010 SPORT TRAC WITH 4.6L 3V ENGINE, AND 2005-2011 EXPEDITIONS AND NAVIGATORS WITH 5.4L 3V ENGINES. SOME CUSTOMERS MAY BE CONCERNED WITH TICK/RATTLE NOISES FROM THE VARIABLE CAM TIMING (VCT) ON LIGHT TIP-IN ACCEL BETWEEN 800-1200 RPM. THIS CONDITION MAY BE MOST NOTICEABLE OPERATING VEHICLE IN CONFINED AREAS SUCH AS A DRIVE-THRU. THE NOISE IS ELIMINATED WHEN VCT SOLENOIDS ARE UNPLUGGED. THIS CONDITION SHOULD BE CONSIDERED A NORMAL CHARACTERISTIC OF THE ENGINE. DO NOT ATTEMPT ENGINE REPAIRS TO CHANGE THIS NORMAL CONDITION. THIS CONDITION DOES NOT AFFECT PERFORMANCE OR DURABILITY OF THE ENGINE.
A light tick or rattle at 800 - 1200 RPM, on light tip in of the throttle as noted above, is the VCT solenoids cycling oil pressure to the phasers once the engine is warm, completely normal. Now a pronounced knock is not normal.

mine is going to the garage on Monday to start on the ticking noise, new cam phasers, timing chains the whole bit will cost about $1,100.00, it may not be an issue but i want to get it done for my piece of mind, i love my truck and want to keep it for a long time yet
