5.4 uses twin Morse heat treated timing chains, they aren't stretching much lol. The EcoBoost only uses a single chain. What happens is the chain tensioners blow out at higher mileage and can’t keep the chains tensioned. I just did all that work to my 5.4 in April. Stout design but the tensioners are the weak spot.
Perhaps the Ford dealership was incorrect. That's what they told me. They said the chains were stretched to the point the tensioners could no longer tension them enough to keep the timing consistent. Wouldn't be the first time a dealership made a mistake I guess.

The 5.4 suffers from timing chain stretch as well. Just had to get rid of my 2013 Exp (It had 178k) as both timing chains had stretched so bad It was knocking quite a bit trying to adjust but couldn’t. And the 5K cost was almost more than the vehicle was worth. Traded up to a 2018 Exp to get to the next generation. Love the 10 speed trans and the power from the EcoBoost. More power than my 2013 ever had and gets way better gas mileage. Even though the tank is smaller it the better mileage makes up for it for me. And just drove from DC To central TX and back last month in the newer one.
Chains don't stretch they wear and never enough to affect timing, they should last forever unless you constantly ran low on oil. I don't think your timing problem was from chain wear but it probably jumped a tooth for some reason. Here comes the opposition........lol

Eric, Have another beer, and formulate a different plan! Last year I "upgraded" from an '11 Platinum to a '17 platinum. Both with the full HD tow package, and a travel trailer @ about 6K lbs. While the Ecoboost has more power to tow, the '11 did a much beer job overall. New one sags more, with limited suspension upgrade options so the overall towing experience was uncomfortable. Lots of cavitation on any highway not in perfect condition. I ending up ALSO purchasing a low mileage 2008 F250 diesel and now I tow with a smile on my face. Wish I had kept the '11 in the first place.

Do you have your scale numbers? I tow 7k with my 2017 and it tows fine.

This video illustrates the problem. Tension can't take up slack in chain. Stretch refers to chain lengthening due to wear, not stretch like a rubber band.

Exactly, that metal is super hard and never stretches. All I saw was a super hyper guy lifting a cab..........:emotions34:

Another round for everyone. So went to pick up the truck today. A/C not working. The heater blows hot. I'm like WTH. Take it back. Get a call that the compressor needs to be replaced.
This car had been on the dealer lot for months btw. Hence the price and I got it $400 cheaper than that. Now it's got me thinking could more be wrong. The good thing is the dealer is going to take care of fixing it. No need to use the extended warranty I bought. It has 140K on the clock, going to have a new AC. Since that happen I felt a little funny about my purchase. Everything else appears to be working fine, except a backup sensor is bad somewhere causing the dash alarm or check backup system or something like that. Hopefully once all this get sorted out I will have a nice truck.

Nice! Wish you luck with your new ride. I’m absolutely in love with my 17 EL so far.

Loved my Ecoboost. Towed great too. I previously had 12 and 00 Expeditions.
