Just sayin ...

 

did a lot of reading last nite on this, and found another set of threads where BioSyn oil was being used to combat this problem with Audi RS4s (as well as other Audis and GDI engines).

The findings is that carbon buildup still happens, but it's alot less and you could extend the time to when you had to do something about the buildup. Apparently Audi's oil-air separator doesn't work too well either.

Also talked about alot was how gasoline was being interjected into the crankcase, making oil particles more volatile and easier to get past the oil separator, and into the intake. And on that topic they were saying Shell or Chevron gas with nitrogen cleaners were helping to somewhat reduce carbon buildup as they went thru the intake port.

I am a EE by training, not an ME or a petro engineer, so I am hardly qualified to judge whether the above is correct. But if one was to believe the tests that individuals ran on their cars, the BioSyn thing may be another solution to AussieKeepers solution.

Also talked alot about oil catch cans was you wanted to get the vacuums and pressures right which confused me as I don't understand the nuances there.

The BioSyn is super expensive btw.

 

Have new cans on and all is well. NO oil in the return tube to the intake, they are clean.
I am happy, my truck is happy. Done.

 

PICS PICS PICS. I saw that for Audi's there were some aftermarket oil can products. Why don't you go into part time business and make up some kits for the F150.

 

I am one of those guys that totally bought into everything Ford was selling about the EcoBoost. I followed all the prelaunch hype, read all of the info that Ford was putting out, watched all the videos, etc. I have been on this site as well as other F-Series sites for over 10 years, and have seen how a lot of people are skeptical to buying a first generation truck or engine. Well, I was skeptical about the EcoBoost, but after all the research I did, I decided to go for it. I am 100% happy with my purchase as of right now (11,000 miles after 1 year), and as of right now I am not buying into these "future issues". EcoBoost is the current and future direction of Ford Motor Company. The SHO, F-150, Explorer, Edge, Flex, Fusion, the full size Transit that will replace the E-Series vans. So, you mean to tell me that FoMoCo is putting this EcoBoost DI technology into this many vehicles, and there is/will be ongoing problems as soon as 15,000 miles. If what you think is true, I think that would mean Chapter 11 for FoMoCo. I hope you're wrong, for all our sakes.

P.s. About 10 people have asked for pictures. Where are they?

 

Will take pics this weekend. If any are interested in the setup get a list together of those that show interest and I will figure out the price for the kit. It isn't really expensive, just cans and some hose and some cutting.

 

Well I read this whole thread but maybe I missed it. How do I check my truck for these symptoms?

 

While I do not know much about Labnerd who you quoted in all of those I have seen him around here for a while. In that time I have noticed he really dislikes the EB and will play fast and loose with the facts to question it. For example this thread: HERE

Once he was called out for cherry picking the numbers to skew the argument he was no where to be found. I have seen this a few times, when sources were questioned poof the vanishing act comes out. I don't know if it was intentional or not but it does cause one to wonder when it has happened several times. Also, the quote you have in the third link is wrong. BMW has NOT stopped selling DI engines. A few clicks on their web site show the 2.0L, 3.0L, 4.4L, M5 and M6 all are DI. I'm sure they have other engines that are if I would have spent more time looking.

DI is here to stay. The benefits of it far outweigh the few problem areas that it has highlighted. Each manufacturer is going a different route to address the issue, some might work better than others only time will really tell for certain. I also would not rule out the aftermarket in coming up with a retrofit cleaning system if needed. The number of vehicles using this is growing very quickly. As this number increases so increases the money to be made cleaning the valves if needed.

 

BG already has an intake cleaning system, I'd bet that it would do a good job on the EB. Expect to pay around $150 to have it done.

 

The catch can's are nothing new for sure. I had an 11 Mustang GT before my Ecoboost and it was the 5.0 and on the Mustang groups, they had found the new 5.0 was putting oil into the intake also.
The expects found it only on the passenger side, the driver side remain dry.
So, even on the new Coyote 5.0, they are putting a catch can on the one side and companies are selling kits for that.
Sounds like alot of the new engines could use catch cans for the oil..

 

Where are the pictures

 

It does not matter as much on the 5.0. Because there is fuel wash over the valves that keeps them clean. Not so with a direct injection motor and that is the problem. Nothing to wash the build up off the valves, so it continues to build until it degrades performance/efficiency.

 

pics and a how to? I'd like to see. My truck is right at 15000 miles.

 

Ok, I finally had a chance to pull my hoses off and check things out. My truck now has 31,800 miles and so far still runs like a top. I planned on using this as more of an exploratory surgery so to speak. If there was a lot of oil I was debating buying a cheap Harbor Freight borescope for $100 and checking out how bad things are inside the intake and runners. This would give me a pretty good idea of the situation. So without further adieu...


I pulled both hoses off and found nothing. The passenger side was pulled first and the inside of the hose had almost no oil inside of it. I sprayed it down with carb cleaner and the cleaner coming out was almost as fresh as the stuff going in. I then pulled the nipple off that connects this hose to the intake and wiped my finger around inside the manifold. I had a VERY slight bit of an oily residue on it but my hands were already dirty from changing the oil and other things around the garage. The driver's side hose was every bit as clean as the passenger side. I took a few pics but there's really not much to be seen on them. So for now I'm a happy camper. I'll keep an eye on it but I'm not too worried at this point.

 

Thank you! Finally, someone who has actually stopped to look and prove/dispel these allegations!
