I love mine. I had a 2012 3.5l and now a 2nd gen 3.5l and I really like the way the engine pulls and the mpg I get. Looking forward to a tuner someday and adding 100hp/150tq or whatever they can do nowadays. The sound of the exhaust sucks and I learned the hard way to just leave it quiet.

In between the eco's I had a 14 raptor and I loved the look and sound of the 6.2l but that truck was always kinda doggy. It was very heavy and the 6.2 took a while to get up into the rpm range for good power. I know it wasn't designed for being fast on the street or better mpg so I decided to trade for a brand new xlt.

Will miss the raptor but also loving the new truck. Sport mode makes it feel more like a mustang than a 5k lb truck.

Just seized again after 70K miles (total of 91K). Likely same issue, intercooler fills with water from condensation then gets sucked into engine. Cant compress water so piston fails and engine damaged beyond repair. First time it did it without warning. Second time, I heard a knock but dead before I could get off the highway. DO NOT BUY An F150 with the ECOBOOST!
Mark Miller's response:
If the condensation problem in the inter cooler was the problem on both engine failures why didn't you fix that problem with a different or aftermarket inter cooler?It looks like guys have put over 150k miles on them with very little troubles.Sometimes the blame is on the owner but they don't see it that way.



I don't understand the logic of either one of these posts............if the intercooler is filling with condensation, then FORD should have to fix it not the owner of the truck who believes he/she bought a quality product. both responses are complete BS.

Agreed! My '11 generates a lot of water through both the intercooler and the PCV system...both are due to bad design. I've done two remedies: Drilled the hole and and installed a competition quality catch can. The hole should take care of the condensation build-up in the CAC and the catch can totally changes the PCV system by filtering out the gas/oil fumes, water and other combustion by products that would be forced right back into the intake manifold without it.

The factory PCV system is one that should only be used on a naturally aspirated engine. Under WOT, the vacuum drops to almost zero and causes all the blow-by in the boosted Ecoboost to pressurize the crankcase and there is no vacuum to assist the PVC to evacuate the crankcase. The "can" I have uses turbo-suction with hoses placed in front of each turbo so, as the turbos spin-up and the vacuum drops off, the PCV continues to evacuate the crankcase, helping with the pressurization problem. If you have not seen a good catch-can working, you would be amazed at the amount of gas/oil fumes condensed in the can, the large amount of water separated and other combustion by-products removed, especially in weather below 45 degrees. My "can" is 16 ounces and I have to empty it once a week during the winter. It also has two check valves to eliminate the possibility of any back-flow. People talk about gas odor in the oil...is that from the blow-by and the pressurization of the crank case? I can't tell you but I can tell you I do not have that problem. Water being forced into the intake manifold is the other problem...it appears to be generated in both the CAC and through the PCV system in the Gen 1 engine. That's certainly not good.

You apparently don't understand the issue. The CAC condensation problem is an easy fix...drill the hole. Ford made no provision for draining the condensation. Ford has not stood behind the problem. They put out a fix where they covered (tape, I think) part of the CAC but it really didn't work and the PCV problem is a major contributor to coking of the intake valves on the gen 1 engine. No fix from Ford. There have been lawsuits that have gone no-where because Ford claims it's a non-issue. Ford has basically taken a stand that says they'll clean the valves as long as the truck is in warranty but if it's out of warranty...owners problem. It seems like the owners who don't put on a lot of miles have the most problems. BTW, I really like my truck, that's why I've taken it upon myself to try to rectify the problems before they become very costly. I've got about $300 plus the new plugs and boots, cleaned the injectors, took the 2 minutes to drill the hole and it's six years old and running great with no condensation build-up in the CAC.

Stupid question.

I am new to the ecoboost family. What hole is getting drilled and where is it being drilled? I have a 2018 3.5 if that matters at all.

dajohu

You shouldn't have to do anything, I beleive it was only an issue when it first came out (2011?). I had a 2012 for 25k miles and didnt have any condensation issues and put 6k on my 17 with no issues either.

If it is still a possible issue then I would ask/reasearch the areas it happens in more often. I think it tends to happen near the coast and southern part of US.

chimmike

you have the second gen 3.5 ecoboost. not necessary.

I'm not a fan of purposely creating a boost leak anyway...that's a sure way to shorten the turbo lifespan.

Thank you for the input!!

Traded in a 2012 F-150 Ecoboost for a 2017 Ecoboost. I liked the 2012, but absolutely love the 2017. Made great changes and updated to the 2017 and the ride, handling and the new 10 speed transmission are outstanding.

I would recommend the 3.5 Ecoboost hands down!

getting rid of my ecoboost that is.
Had an ‘11 that the timing chain stretched on so I thought I’d just trade it in on a ‘16 5.0.
Should have just repaired and kept it.
5.0 is nice but it’s sluggish and worse mileage. Really notice it towing even with the increase in HP.
