V6 longevity aka V8 hater thread

The 2.7 in the 15-17 had some issues with an oil feed line to the turbo and leaky plastic oil pans. The 18 plus from everything I have read have been rock solid reliable. On the f150 forum the guy had over 465k on his 2.7 original motor and transmission.

Interesting about the GM 2.7... I just visited the Chevy configurator and had a look. First, that comes only with the troublesome 8-speed trans, and then even starting at the higher RST trim if you add almost any of the packages it bumps you into a different engine and transmission.

 

3.5 Eco had sludge/gunk issues from the fuel injection method that were remedied only to lead to cam phaser problems which resulted in a redesigned part after about 2020. Also some timing chain issues had to be addressed. So theoretically my 2021 Gen2 is the version where common issues that have cropped up since its intro have been remedied but I guess we'll see. So far 11k and GTG. Some of the problems were rumored to result from Ford recommending excessively long oil change intervals so I am staying with 5k/6months as in every other vehicle I ever owned even though my powerboost with intermittent EV mode is supposed to be able to go a year or 10k

 

Well, after 15 years of working every day with most of Ford's offerings, I would never buy a Ford. They have the stupidest issues. It's ridiculous the annoying things that break on them....
I mean, I had a Transit Connect 1.6EB with 12k miles on it, when the heater would stop working, I knew it was time to add coolant.

Anyways, I think the real reason Ford continues to offer NA engines in the F-150 is because some fleets have managers who either never trusted boosted engines, or became fed up maintaining them on a municipal budget. Some municipal vehicles have shortened warranties due to their use or modifications, I know they would go to the dealership when brand-new, but I'd also see 2 years old trucks getting engine-out in our service bays.

Toyota can force a turbo only lineup since they don't have to answer to fleet customers.

Oh, and BTW, I am not a fan of my new truck at work. I used to drive a 6.7 Powerstroke, when running right, it drove so good. My new truck has the 7.3 in it, definitely not enough engine for a bucket truck. However, even after 18 months, not one single issue with the 7.3 drivetrain. The 6.7 was BAAADDDD, CEL almost always lit....

 

Yea my 17 3.5 ecoboost had phasers done at 89k miles. I’m at 108k miles now. Thankfully ford came out with a SSM and I was covered under an extended warranty up to 33 percent. Paid 1300 bucks for new phasers, chains, guides etc. Paid a little extra for a new belts and a water pump while they were in there. Without the Cam Phaser problem those Gen 2 3.5 are pretty darn reliable. Don’t hear much about them besides the darn cam phasers. Hopefully the Toyota 3.4 gets all the kinks out too. The recent threads about these spinning bearings is worrisome. Might switch over to Toyota in the future we shall see.

 

What’s crazy is the 6.7 powerstrokes in my ambulances at work have been great. Started up full throttle immediately to the call then pulled back in the station and turned off. They get idled a lot too and are still doing good at 100k miles. It’s impressive.

 

Yup, mine was a 2015, I heard that later years were far better. We had 2018+ that seemed to never be sidelined.
Still, us being "beta" for the initial 6.7 was enough to have them banned from our fleet.

 

Our district is moving to 7.3 gassers as well but it has to due to with fuel prices since our diesel budget tripled last year.

 

I bet your drivers are going to miss the 6.7! It's a beast in these heavy vehicles

 

I’d stay clear of GM due to their support . If you find acceptable to wait 3-5 months for a transmission then you’d be ok . The dealers buy me are terrible

 

Agreed! This is the reason why i'm looking to trade in my 2.7 Ho to get back in a Tundra. Don't get me wrong I absolutely love this engine! The engine itself I have never had issues with, however my truck has been to the dealership atleast 5 times since I bought it new 5 months ago and the dealerships have always been terrible! Now im feeling that terrible 8 speed starting to give out. Its makes such a loud clunk noise when going from 1st to 2nd and its super rough. A few days ago my engine just shut off on me when I was accelerating from a stop. Error message popped up on the screen and read "put in neutral to start". Im looking to get rid of it before the transmission goes out caused I'd be damn if my truck will be sitting at the dealership for 3 months waiting for a new transmission like alot of people have been doing. I use my truck for work and cannot work without a truck so thats it...bye Chevy.

I never understood why GM decided to continue using the problematic 8 speed instead of justing putting in the 10 speed with the 2.7

 

Ya they could even break out the old 6 speed which was way better than the 8. Their 10 speed seems to be hit or miss. I test drove a Sierra with the 10 speed- the Toyota 10 speed is a little better IMO.

 

I think it’s up to GM to prove they can outlast Toyota not the other way around , 1 video doesn’t change the fact of Toyota having the long term historical advantage

they are both new so I would bet on Toyota hands down since both are uncertain at this point

 

Toyota knows their way around a v6 engine. The 2jz engine is one of their best examples of this. That engine can take a beating and still go on to last to 200k. I am not saying our engine is the next 2jz but one hopes that they put that type of expertise in these engines.

 

The GM 2.7 does look to be pretty dang legit. But I wonder if it is just as likely to gain the reputation of an older Dodge with a Cummins…the engine is solid; it’s just the rest of the truck you have to worry about.

 

Yup, like a building in an earthquake where the elevator shaft is left standing in the pile of rubble from the rest of the structure.

 

I had the 2.7 v6 ecoboost in my Bronco. Haaated it. Sure it was reliable, but it shuddered at stops and the turbo lag was crazy. And then it had an issue with the oil pan leaking, Ford replaced the oil pan, but it was a 5 week wait for parts. The dipstick was also the wrong one, so it showed the engine was overfilled when it was really underfilled.

Don't even get me started on the transmission. I had my bronco for a year and put 17k miles on it. Averaged 16.5MPG in that time. Couldn't wait to get rid of it.

 

We have had lots of different motors on cars in our family go 300+K miles with little to no issues. four, six and 8 cylinder engines. Take care of them proper maintenance, dont beat the crap out of them, dont modify them, they will last. Best one yet was a ‘88 Saab SPG 4 cylinder turbo that went almost 500K. Acura RL that went 300K. Guy i know has a F150 6/turbo with 300K, no issues. My 08 5.7 went 286K but only because the truck got totaled not engine failure. Mazda 6 went 200K and was running great when’s e got rid of it. I expect to get a solid 300K out of my new ‘23 Tundra. I dont think it has anything to do with 8/6/4 cylinders.

 

@wedemmoez - doesn't the Bronco sort of have an issue with that motor grenading (amongst other things)?

 

LOL.

To begin with the 2jz is not a damnable V6 in need of balance shafts or other nonsense to not shake itself to bits.

The 2jz is a glorious inline 6 with 7 main bearings, and inherent primary balance.

The V6 is an engine solution for getting 6 cylinders into a front wheel drive car. It has no place in modern vehicles with the advent of turbo I4’s to achieve that power in those applications.

For reasons of economy of scale to save money Toyota and Ford have seen fit to curse their trucks and SUV’s with longitudinal engines with shit ass V6’s because they have a bunch of foundry equipment to make V6’s.

This is clearly an inferior solution to an inline 6, but they don’t care because it saves them money.

 

there were a few that blew up, but I don’t recall it being widespread.
The current issue (that also affects the bronco I just sold) is that one of the techs accidentally inserted an extra bolt in a non-threaded hole in the transmission, which falls out and destroys the “park” mechanism. This cause the bronco to spontaneously roll away.

 

I left a 20 tundra for a 22 3.0 . Loved the truck but the dealership was terrible . Not to mention waiting a year for my heated and ventilated seats to be installed . I gave up on waiting . Our stories are very similar . I traded it in before the value plummeted any more . It ain’t like 3/4 ton diesel as far as value

 

Well said. My 2017 TRD PRO was my first and will likely be my last truck. As much as I like it, for all I want and hope to do, I should have gotten a 3/4 Ton, and the F250 with Tremor or Black Package looks very appealing to me.

That said, the 5.7 chassis is a tried and true workhorse, and I'll take the lighter payload and towing capacity, though it was hard to pass on the toyhauler we were eyeing.

There was an article back a few years ago calling the 2017 TRD PRO the last of the honest trucks. I feel that way. My truck has everything I want (after I added heated seats) and nothing I don't. If something catastrophic happens and I had to replace it, it wouldn't be with one of the new Tundras, it would likely be with an F250 Platinum or Lariat.

I would be surprised if the new powertrain doesn't EASILY make it in to the 150K range, but that is to be seen. Most of them will likely see light duty, but the new Trans and Turbos are what I'd be keeping an eye on.

 

Everyone thinks the next new Toyota is the end to “Toyota Quality.” They’ve been mostly great for decades and will continue to be. Sure, they might have some clunkers along the way as any manufacturer would. Biggest one I remember was 33 years ago with the 3.0L V6 that was awful by Toyota standards. but for the most part they produce phenomenal rigs year after year, even when the generation changes

 

yup, the 22re also ticked like a mofo which most people now a days would say , o it’s a pos.

known to us toyota dudes as the Toyota tick, yes they tick forever, ha!

 

if a toyota engine doesnt tick, then i would be worried

 

What's really interesting, is they make it even more confusing for the average owner.... You have to remember to disable stop/start so the truck doesn't try to damage itself in certain situations.....weird

 

meh, thats just to cover their asses, the turbo timers back in the day were like 10-15+ mins, not 1 min

also I doubt anybody can roll off a track, limp through the pitlane and get back to their pit in 1 min

nor do ppl live like 5 ft from a 62+ mph freeway where you constantly cruise and they can literally pull off of and go into a driveway, thats just highway cruising, you get off the offramp, a city block goes by and its already a min+

i climb a .5 mile 3000ft ascend everyday at work, it drops my mpg like .1-.2 everyday, but once I turn into my works parking lot (i go through the smaller delivery road so its shortcut), its already a min before I could park - even if I take the shortest parking lot available to me

tldr, they dont just run air through these intercoolers, they got liquid cooling as well
