Our company has 10 ecoboost F150's and the lowest mileage one had 60,000 miles on it I was bored today, being everyone was sent home for the holiday weekend and decided to take a look into this and found pretty much nothing out of the ordinary. Ya there was a slight residue but nothing to worry about, There trucks are all oil field vehicles put on 300+ miles a day on dusty dirt roads, with constant loads in the bed/ pulling trailers.

 

Drained a tablespoon from each canister today, Return lines were spotless.

good luck to all of the non-believers........

 

How many miles was that over? A tablespoon is .5 Oz so it could add up pretty quickly. At least enough to show up on the dipstick when it's time to change the oil. So far my truck has not been using oil between changes. I have been going 5-7k between changes.

I curious why your truck is putting out oil but mine isn't. How many miles do you have and what is your driving style like, what kind of oil have you been using and how did you break your truck in? Off the top of my head these all could have an effect on the oil in the PCV lines.

I now have 32k and drive pretty hard most of the time with about 60% highway miles. I used Motorcraft synthetic blend for the first 20k or so then Castrol Edge for the last 12k. When I broke would let it come up to operating temp then drove it pretty hard.

On a side note, I noticed the intake manifold has a top cover on the plenum that looks to be removable. If it comes to cleaning things out the that would eliminate removing the entire intake manifold to get down the intake runners.

 

It was after 3 weeks and 700 miles, so, all in all, not too bad. However, NONE is better than SOME.

Mixed driving, mostly city.

 

Take any pictures yet

 

since some in here seem to not have this issue (see above posts), maybe it's just your truck...might wanna get it to the dealer and show them your findings.

 

They can do what they want, I do...........

Sometimes I get some oil, sometimes I don't. I DO know, however, that NONE is getting into the intake or valves.

I really have heard too much denial on this subject, do what you want, I personally am tired of beating this horse..........MINE IS FIXED.

 

Oh okay, I get it...no one else is having the same issue, but just because YOU said so, everyone else is wrong. Good luck with that.

 

Very interesting thread. I want to add my 0.02 worth. I have a 2011 EB with 14000 km's on it. Currently it is being converted to run on Compressed Natural Gas (CNG). Part of the conversion process involves removing the intake manifold to install the injector tubes to the heads right at the intake runner.
I called the installer to see how the conversion was coming along and he commented on an slightly oily build up on all of the intake valves. On each cylinder one valve stem/valve head has slightly more build up than the other. He has taken pictures but not forwarded them to me yet. This concerned me and lead me on a search of intake build up and I first found all the VW/Audi posts and now I am here.
I'm going to look at the PCV tubes mentioned above to see if there is oil there and if one side has more than the other.
Aussiekeeper it would be very helpful if you could post pics of your setup or link to where I might be able to purchase the canisters.
I am overseas working at the moment but will be returning in a few days. I will be picking up my truck from the installer on Wednesday. He has it running on CNG and says it runs very well.
If he can email the pictures of the deposits I will post them.

 

ALL of the EB's are depositing oil into the intakes on these. Some here seem to believe their engines are the "magic exception" of the rule. If any of you want to see the install, e-mail me and I will e-mail some pictures in return. Sometimes on one side, sometimes on both. Maybe something to do with how often boost is used and for how long..........

 

No problem, you are the one who will be standing on your engine with a jack hammer removing the coked oil from the valves........lol

 

See post #86............

 

Hmmm ...

Well, so far, I've gleaned the following:

It's a directly observed phenomenon that affects multiple different makes and models using gas DI technology, in pretty much the same fashion.

No manufacturer, despite claims to the contrary, has actually fully addressed the problem

You Cannot determine the extent of the problem from indirect observations - e.g presence or absence of oil in the PCV tubes is a non-sequitur. One can have 'Dry' tubes and still exhibit deposits on the valves.

Only Direct observations of the intake valves themselves, and/or measurement of oil output as captured by the canisters, if installed, will indicate the presence/absence of this issue.

Canisters appear to be the only currently known method to redirect the oil from the valves.

Those without said canisters are secretly wishing they had them - if for no other reason than to measure their specific truck's predilection of producing this issue.

Installing and maintaining the canisters is such a trivial and inexpensive task that one has to wonder why folks just don't go ahead and At Least try it. (Said another way - if I had an EB, they would be installed on Day 1, given the preponderance of the evidence, here and elsewhere, Labnerd's endorsement, my own research, and My Own peace of mind.)

Lastly - Denial is a very powerful force. Just ask Bashar Assad ....

And once again - my hat's off to Aussie for your efforts! Whether other folks appreciate it or not.

( and - very sorry for yer recent loss )

Cheer, beers and Good luck to All - this be merely my Opinion, okay?

 

Thank You..........realization and clear thought processes are refreshing.

And thank you for mentioning my loss, that was 2 in the last 9 months.

 

Splain yerself, the tubes are the way the oil makes its way into the intake. If the path is clear how else would the oil be getting past. In my experience oil is a lot like a snail, if it has been there it will leave a trail. Aussie said his were 'dripping oil' mine were dry. If the oil is being caught then it was in the tube. If the tube was dry then how was the oil there?

Y'all do realize the PCV system works on differential pressure...

-How much loss was induced by adding a bunch of extra hoses and cans full of steel wool?
-What effect will this have on venting the pressure out of the crankcase?
-Will this extra pressure cause other problems like blowing out seals?

I'm not denying anything, I have several friends who are VW/Audi techs they know all about the carbon on the valves since the early versions of these cars were the worst. Also, even if you were to never have a single drop of oil enter the intake there could still be a problem. There could still be carbon build up from the blow by while the valves are overlapped. Ford says they have solved this issue too, who knows for sure?

I plan on keeping an eye on mine to see what happens. Right now mine is not showing any of the symptoms of the carbon on the valves, my mileage is as good as ever, the power is the same and it runs as good as when I drove it off the lot. I still might spring for a cheap borescope to take a look but for now I'm happy.
