2013 Ford F150 3.5 V6 Ecoboost and should I tow with it??

Hey, I joined just to try and clear the air with the Ecoboost and then with DI in general.

DI and turbos have been around for decades, DI being much older of the two. DI only recently gained popularity because of computer controls to better allow for more precise fuel management. DI engine have several advantages, one being it can fire nearly time except for on the combustion stroke(but it's best only to fire at certain times). The low end torquefound in DI motors is akin to diesels when they accelerate, they produce a large amount of Particulate matter. The revision in the ecoboost is to better fine tune the injectors, gasoline injectors only have so much pressure, and the injectors only have so much duty cycle. So when you have a high output motor you sacrifice some resolution by going up to bigger injectors. So in order to better get a handle on emissions they use the port injectors to supplement the direct injectors, this allows both the DI system and the port system to be more precise and have a better range of operation.

Fords system to my knowledge is not prone to carbon build up. That's with personal experience and some research on the matter.

As to using a fuel induction service, most manufacturers' don't recommend it, it can burn up /clog your catalyst. If your car is having problems, the induction service only mitigates some of the symptoms if any.

Yes, fuel wash and swirl past the valves with detergent gasoline can help keep them cleaner than they would otherwise be, but a good DI setup will plumb itself in such a way that it doesn't matter. There are good and bad DI systems, I don't think anyone should second guess the ecoboost motor because of it.

Odds are with most modern day cars, your engine will out last your frame as long as you properly maintain it. Sure things might go wrong here and there, but quality is vastly better now a days, even compared to just 10 years ago.(I might not be able to make that statement much longer with all the trucks and things going to aluminum)

My cousin started as a Ford tech in 93 and for the last few years been working in the Chrysler shop. He also mentioned the carbon topic has not been an issue with the EcoBoost.

The problem isn't so much the turbo's, it's the direct injection and the resulting carbon build up at higher mileage.
Fords fix in the past has been to replace the heads.
And it's not a "Ford" thing; any gas vehicle with DI is subject to this problem. That's not a reason to not tow with it though.

Now someone is going to come on and say they have 3 million miles and never heard of this or that I'm some sort of anti Ford guy. My history of posts proves otherwise and besides, I owned lots of Ford and Chevys.
I suggest you do some internet research for yourself.

Agreed. The weight is fine for that F150.

The DI engines need more maintenance though, no matter the brand. Our fleet of EcoBoost Police cars and F150s all get a BG induction service regularly to keep the carbon built up at bay. We have had a couple turbos blow, but the EcoBoosts haven't been any more troublesome than the other makes and models we use.

My 2013, 3.5 EB, 3.55 axle, RWD, Supercrew 145" WB with 1607 lb. payload tows my 27.5 ft. 6740 lb. loaded, 780 lb. tongue weight, toy hauler. The 7100 lb. GVWR truck is loaded to 6920 lb., 97% of GVWR. I would not want to tow anything heavier. The engine is hardly taxed, but the rear suspension is compressed. It now has 96,000 miles on it and still runs great. I've had to replace the tires, front and rear brake pads, front brake rotors, windshield wiper switch and a turbo boost sensor. I am very pleased with it.

TnP. You haven't owned the engine in question. You can't POSSIBLY have useful information....... ;)

Now you're cooking with peanut oil!!!!

TnP, why do you keep spreading false information? I thought you were better than that. Ford did NOT put port and direct injection on the Gen 2 Ecoboost due to carbon issues. They did it to meet emissions. more power, and fuel economy. I posted multiple links stating this so why do you continue to post false information even after knowing the truth?

Also, just because someone is gullible enough to get sold on a catch can and you post their link, does not mean there is an issue. I was a very active member on that same F150 forum for years up until 2015. There were many members who were sold on these catch cans(even the 5.0L guys with port injection) as "cheap insurance" even though they had no carbon buildup issues and many other members were going hundreds of thousands of miles without them and zero issues due to carbon.

What these guys failed to figure out is that port injected has carbon build up on the intake valves too. This is why some black smoke comes out of the tail pipe when you floor it after driving conservatively for a while. So just because they see some carbon on the valves does not mean it is not normal or is harming the engine. It is when the carbon buildup is causing power loss, compression loss, or other mechanical issues when it is a problem. If the amount of carbon on the valves is not causing any of these issues even at 150k or 200k like many have done, then you are not having carbon buildup issues.

So until you can post where the carbon buildup was causing any of these issues on a regular basis, then I would stop trying to scare people with non issues.

TnP. You haven't owned the engine in question. You can't POSSIBLY have useful information....... ;)

Op, you might want to read this thread Link where someone who owned one of these engines pulled the heads off at 70K and see what they found.

He mechanically cleaned up his valves and installed a catch can. The reason for the valve carbon problems is the PCV intake line is placed in the intake tract. If you live in a warmer climate the oil gets fumie and is sucked into the intake tract where it can carbon up on the back side of the valves because they are very hot.

The catch can idea keeps the fumes out of the intake tract and keeps the valves clean. It's a pretty good solution to the problem.

Ford saw the light and fixed this problem once and for all with their port injection. :)

I think the head replacement is just a symptom of modern throw away culture. A $.50 resistor goes bad on a computer board and you are told that you have to buy a new board for $200. No body wants to "fix" things anymore.

The issue is carbon buildup on the back side of the valves. I believe that very few dealers can do a "carbon and valve" job anymore. Have an independent shop pull the heads and clean it up. Minor cost compared to new heads.
