Ford eco boost

[RB5]

I thought long and hard about whether or not to go with the 3.5 Ecoboost in 2013 when I bought my F150. I was leaning toward the 5.0 mainly because I thought it would last longer. I knew I did not want a Ram after my 97 fell apart. I won't go into details. My 2013 F150 4x4 has 270k miles. The only issue other than routine maintenance I've had was a valve spring broke at 61k miles. The dealer got Ford to cover it. I'd had all my service done there, and they told me that should not happen. Cost me $200 instead of $3500. This has been the best truck I have ever owned. I'm skeptical about the new ones. All the extra mile to the gallon tweaks with the 10 speed transmission and the cyllinder deactivation add too much complexity. I recently drove a 2.7, 3.5, and a 5.0 back to back. The 2.7 surprised me and was not bad. The 3.5 took a second for the turbo to wind up, but was very strong after it did. The new 5.0 was a beast. I'm getting closer to buying again and am starting to see deals locally that I have not seen in years. People are running out of money I guess. My 2013 was $11k off MSRP when I bought it. I asked about cyllinder deactivation on the 5.0 and did not really get an answer. I am now trying to decide between the new 5.0 and the 3.5. I'll bite some time in 25 if the right deal shows up.

Y'all are lucky so far. I have read that the Ford ecoboost to treat it like the plague.

Common issues with Ford's EcoBoost engines include: carbon buildup on intake valves due to direct injection, intercooler condensation, timing chain stretching, ignition system failures, coolant leaks, turbocharger problems, and potential issues with cam phasers;

Nah, almost none of that is true for the 2nd gen 3.5L EcoBoosts engines built from 2017 onward - except for the Cam phasers.

My 2019 3.5L is at 70k miles now (bought used at 54k miles) with zero cam phaser noise on the original units. I intentionally do a "flood start" to build oil pressure before letting the engine fire, anytime it has been sitting for more than 8 hours or so. But I know the phasers may still fail eventually, and that repair not fun to pay for, and is so complex that it often causes extra trouble. Zero check engine codes or trouble of any kind since I bought it.

I tuned my truck with an SCT tuner and their off-the-shelf 91 octane tune (I run 93) and it is insanely fast. Getting ~21mpg summertime, ~19 mpg fall-spring in mixed suburban driving.

They dont stretch, they wear and its from poor quality oil/ or long oil change intervals.

Exactly and last time I checked, timing chains had no brains so they cannot be stupid. I watch the YT channel 'I do cars' a lot and they tear apart all sorts of engines and every one where the oil was neglected, the insides of the engines look like hell.

Modern multi grade synthetic motor oil likes making sludge and staining engines internally.

Ive never heard the term "flood start". What is it?

I get 21 out of my '97 7.3 turbo diesel average and my diesel will be running fine when yours is at the scrapper.

the cam phaser issue was resolved during 2019 builds, ive been told. ford has extended warranty for that issue past original warranty. mione was assembled later 2020, so hopefully im free of all that junk. i like my 3.5l unit. has great power and response. extremely happy with it, but i did delete that stupid engine stop switch when idling at stop lights, etc.

Of course all of these problems stem from our
trusty govment sticking their nose in things they don't have the knowledge to know what they are doing except to cost the tax payers more money for all the crap they have to add to the vehicles if they would just let the engineers figure out what is needed we would probable have vehicles with a lot less problems

i do miss my old 1975 F350. i could climb into engine area with hood up to work on it. sooooo much room. i wont touch any of my newer rigs.i have a good and trusted mechanic for that. heck, there so crammed with junk, i cant even trace a spark plug wire.

I have a 2013 F150 ecoboost. I had the first timing chain stretched and needed to be replaced at 60,000 kms. Thankfully it was under warranty. Now the truck has 174,000 kms and now the stupid timing chain is stretched yet again and needs to be replaced. This time not under warranty unfortunately, which is going to be a huge repair bill. I am so angry about this. Clearly this is a poor design with so many other ones having failed and now it has failed again. I was going to buy the 6.2L at the time and salesman talked me into the ecoboost. I am so pissed off I listened to him. I do not drive this truck hard at all and barely tow anything at all. It is absolutely ridiculous the timing chain is stretched yet again, which means once I replace it then it just a matter of time before it gets stretched again. Piece of junk ecoboost.

My timing chain was done around 210,000 km (130,000 miles) Independent shop did it for under 3K. Mechanic thought motor had never been touched before that. The chain was well worn, tensioner was fully extended, but the truck ran well enough to tow. Was throwing codes and had boost lag bad.

Oil change ever 5-6000 km with full synthetic, ignore the oil life thing in the dash.
