If you think in 1000's of hours run and it is hard to get past an average of 35 miles per hour run an the problem for most of build up really begins at 2500 running hours then you can see 75000 miles is the stickler where many will observe the problem beginning. 2500 running hours to 3500 operating hours is the quite common point of problem magnifying. Removal of the pcv mess will certainly stretch the running hour aversge out past 4000 operating hours but the intake valve guides will wear open allowing increases build up on the valve stems at that point where 140,000 miles driven becomes almost a sure point of problems. I am simply stating an odds on answer. Some will do better an reach 4500 to 5500 hours running time or 175000 to 200000 miles befor head trouble with the PCV problem removed from the valve bake on situation.

Funny, I thought this thread would get a bunch of activity as it confirms one of the issues related to the PCV system....lots of great data here for all wanting to learn.

Except the only "issue" is that on the 2.0 (which 0 F150's use) the PCV dumps into 2 and 3's intake tract. That may or may not cause issues. Even the OP states he may have a leaky valve seal in #2.

Basically the same problem occur with all 4 cylinder motors with PCV dumping into the center. It isn't a new thing only the gasoline washed part of it away also cooling the valve. Put a dry fuel on it and bingo much more build up on the intakes. Reduced carbon in the cylinder and longer bottom end engine life. But you had to do some valve jobs. Guy's who love to keep cars for 20/30 years of use deal with it mostly as second nature. The gasoline guys just wash their bores out .006" or more and lose compression and have blow by. An its Jasper to the rescue.

Yes but many people misdiagnose this concern as a reflash or spark plugs also many don't come on the boards and express their concerns. Also we see plenty of these in for other concerns and people just beat on them and they don't run right and if it starts up, down the road it goes where as this is my own vehicle and I am a little more sensitive. You should see the amount of new edges have a horrible brake squeal when cold never had anyone complain and it is loud! The first one I fixed was for a Chrysler tech here at the shop that bought a 2013 Edge he had us fix it because he knows it is not right. Does that mean the edges don't have brake noise concerns just cause no one complains?

The 3.5l has it's own air flow issues with the intake design that is why when the 3.5l has a misfire due to the water from the intercooler problems TSB it all ends up on Bank 2 every time, Same thing.

Not trying to hijack this thread but how do you fix that brake probelm on the edge !!! My mother has one and its driving her crazy its been to the dealer several times ?!?! they keep saying nothing is wrong with it !

Feeling philosophical this morning! If a tree falls in the forest and nobody is there it does it make a sound? If a vehicle had an issue and nobody notices, is it a problem?

I thought all anybody did on a forum was complain! I'm kidding. Mostly.

You are right that I have no clue what is being reported at dealerships, but I can tell you their response when you take in an ecoboost truck with less that 1000 miles with a rough idle. "Normal characteristic of that vehicle". When properly gapping the plugs often clears it up substantially.

The ecoboost definitely has it's share of issues, but yours is the first publicly documented case of an this being a problem. Though there may be thousands more whose dealers are telling them it is normal. But at this point, yours is more of an anomaly than a trend. Timing chain problems is more of a trend. And the scary one too....

Just out of curiosity, what would the non-warranty cost of the repair have been? Ballpark? I'm guessing substantial.

Many times the OEM knows and tells the dealers to only do it if a customer complains an do not acknowlege it at a ytime to anyone. Simply put, charge it somewhere else an we the OEM will cover.

Tuner Boost

Correct. And that is standard with all auto makers. No brand wants to bring attention to issues that most drivers are not acutely aware of. We are into our second generation of drivers conditioned to just drive and put gas in and not understand anything about the vehicle they bought other than how it looks.

Here is a recent can drain on a EB F150 after 800 miles:



This would not be good if left to mix with the oil in the crankcase or the CAC and be ingested with the intake air charge.

Yet millions of Ecoboosts do just that without issue. Those that have had oil analyse done show nothing abnormal unless there is an underlying issue (fuel pump, etc.)

Also billions of engines have that stuff in them too and go hundreds of thousands of miles without issue.

IOW, not a concern at all.
