So by "officially solved" you mean having to replace the cam phasers (and associated timing components) like I just had to do on my 2011 EB, at 77k miles? The "solution" being replacing under a TSB if/when someone comes forward with an issue?

You mean that is the year they stopped putting the 5.4 in the f150
The TSB for the timming chain/ phaser issue goes all the way into the 15s when i drop mine off on thursday ill get the TSB#

I had an 04 until I sold it when I bought my 13 Eco brand new. I did my research when I had my old one and they fixed the 5.4 back in mid 2007 so they late 07 models didn't have the tick and it obviously helped prevent the "throwing" of the timing chain.

You bought an EcoBoost. Cam phasers are the least of your concerns going forward.

Correct. When the 5.4L was dropped, so were most of the problems. Sure, EARLY builds of the 5.0L had a few issues, but overall it's been pretty rock solid. The 5.4 had issues from start to finish during it's run.

Having the front end of the power plant basically replaced is the least of my problems? Well then, Seer WX, since you can apparently see into the future, what other "most of" problems can I expect with the EB platform? You know, aside from the canard of issues that these forums are full of: IC-related issues, DI-related oiling buildup (see also BMW, Audi, etc.), 55mph shuddering (which the "rock-solid" Coyote has also reported occurrences). Every mass-produced (and there are a lot of EBs out there) platform has some associated issues; it's inevitable. 5.4, 4.6, 3.5EB, 5.0, 6.0.... all have had issues; making vague references to the impending doom of one platform (because you have a different one and are apparently pleased with it so far) and not offering anything constructive, is a chump move - especially on a forum ostensibly here to offer guidance and assistance.

I concur...I asked specifically what were the other problems or whatever and heard nothing. And when I mean problems, I mean to a great enough percentage of models to warrant a problematic concern.


thanks, tstex

Got to say I agree with the above. If someone is so fearfull of the new tech they should just go back to the flathead carburated inline motors. Or, we have a large Amish community in my area that are always looking for some good strong backs to take into the fold.

I know this is an ancient post but it still gave some information that helped me so...
Timing is everything: the 351 Windsor used to stretch the timing chains. You could turn the distributor, set the timing right with the timing light everything perfect. It would run fine then would come out of time and stopped running. Likewise chain stretch on the 5.4 three valve seems to be the central problem that occurs from all the poor oiling conditions. Solution? Replace Chain guides chains cam sprockets/ phaser assemblies chain tensioners. The whole timing chain kit and then with any luck you can expect to get as many miles as the previous timing set. Given that it had a good run. I have seen timing chains so sloppy after the guides broke that the chain slapped a hole into the engine front cover and blew oil everywhere. But the truck was still in use, came in for oil leak.

Nope ..they did NOT FIX THE PROBLEM. I have a 2007 F150 with the 5.4 in it and it rattles like hell at an idle or when under a light load moving slowly..( I e. Pulling into a parking space or backing up ) and dies more times than not. That engine is JUNK. And the engineer? Should be shot
