My credo
Give me money.
Coking of the intake valves from DI only and the 'catch can' fix is all internet fueled rumour mongering. Unless you have a photo of a DI only ecoboost engine you have owned and took it apart yourself and found that the intake valves were coked and nasty from not getting washed off with port injection and you then added a 'crankcase gas condensating bottle' and then tore the heads off again and found pristine intake valves. Also, please don't be argumentative because I will not reply back to that. Thanks.
What makes you think the ford gdi system is any different than any other manufacturers gdi system? VW has been dealing with intake issues on their GDIs for years and catch cans have proven effective. And now they run the dual injection simply to solve the gdis inherent design flaw which is still only partially effective.

After 8 years of being in one of the best selling vehicles plus many others recently why is VW still the example to be compared to?

All things equal there has to be a lot more 3.5’s out there than all VW’s combined. If they were having lots of problems nobody would care about the VW’s, ford would be front page news.

I can’t speak for VW but later model 3.5 Ecoboost engines have both direct injection as well as port injection to combat the issue.

I don’t know what other models of the Ecoboost engine have that outside of the 2.3 in the Ranger not being one of them.

So, the issue is something to keep in mind though it isn’t as bad as it was in the past.

It could very well be like the burnt valve issue in the B20Z Honda engine used in the Acura Integra and CR-V where it is a known issue that can cost thousands of dollars but not a common one. Honda and Acura approach the issue differently but the fix in either case is to inspect and/or adjust valve lash every so many thousand miles to make sure it doesn’t happen. Being that most people aren’t going to do it (assuming they even know about it) and engines aren’t failing left and right, speaks it not being a huge issue but yet an issue.

At this point, the coking valves in the direct injection only engines may be similar to that. There certainly isn’t a huge amount of coverage on the subject. So it may just be a concern to look out for rather than one that all the engines are going to fail.

it is easier to fix and understand than "her"
it is an issue. severity is drive cycle dependant. but its like 100 percent will be rough running, to the point of coding in some cases, specifically because of it...before 100k

what is detectable by some wont be noticed by others...my daughters 2 month old 2.7 is a piece of shit. not impressed at all with it for cold starts.

simple intake cleaning clears it right up if caught in time....put that in on a tire rotation schedule.... i have never seen one with more then 60 k that did not have shit on the valves. and this past week i looked at at least 50 engines doing research on a unrelated subject..

dual injection is a fix because it is a real issue. it is inherent with gdi.

not internet folklore.

Says some guy on the internet. ;missingteeth;

That said the new PCV systems are getting better at drawing out oil vapor. When I was looking at Challengers around '12-'13 catch cans were all the rage on the R/T's because the intakes were filling with sludge from the PCV.

My brother put a programmer on his '11 Coyote and it had problems with the PCV vapor (because of the piston cooling jets) and he had to get a catch can for it.

Might not be bad thing to do no matter what engine you get anymore. :dntknw:

And then there is my old pullout '87 5.0 that has a bone dry intake although it should have more stuff floating around in the crankcase than all of the other three combined x3. A generic PCV in a Ford Racing valve cover must not be that efficient compared to newer PCV systems.

EDIT: Talked to my brother, he thinks it is more of a urban thing. He knows it is a thing but out here in the sticks where everyone runs quite a bit of highway it isn't a big problem.

Just read a new report that says the wheel does NOT need to be removed to change the filter. Just remove 3 of 9 fasteners and open a flap. So sorry if I was part of the hysteria and/or confusion.

Much better than the original info!

EDIT: not sure how to take the “whole five people who do their own oil changes” comment...

like i said.....not internet folklore. i dont have facebullshit. dont belong to any eco forums either...probably the best place to check.

but i do associate with people who have to work on these regularly...


i have trs and pirate 4x4 and diesel place, a gm sight..where i tend to spend online time...there are various other ranger sights i visit on occassion but very little time.

none of these places have ecoboosts(yet) as any sort of advanced topic.


but i have ecoboosts....most of my kids have ecoboosts....most of my whole family have ecoboosts...i work in an unforgiving environment for any vehicle. and see first hand every manufacturer get its ass kicked daily...

we are not allowed to have any turbo anything at the company i work for based on operational costs of anything turbo for the amount of idle time that is part of the operation. especially modern diesels.


for sure... drive cycle dependant. out in the sticks..all high way....no issues. sure there is shit on the valves....not enough to care about. shitty idle isnt costing much..



and the 5 guys that change their own oil will probably still relocate the filter on these new rangers so its not making a pathetic mess from being sideways..... and taking apart the wheel well regularly is a stupid idea for keeping its function intact long term. unless they actually built one that is stout. time will tell.



bring em on in...

I would be one of those five guys and, depending how much of a pain the filter is, may install a relocating kit.
