Another blown ecoboost Engine

What you don't like in my sentence? Why did you call me fool?

Because your statement is full ignorance and lack of knowledge or facts.

Hah. Ok:-)

 

[2015 Silver GT]

Dang, a little touchy. As I said I will create my own post later this week. I want my car back first so I can review everything ford found so I can add more to this discussion.

Short story, my engine blew up 3 weeks ago. It had nothing to do with lspi, oil issues, that I know of or crazy mods. It happened it 2nd gear at about 4K rpms. So people constantly saying don't gun it in high gear and you will be fine are giving people bad advise.

Not that you've gotten your car back I'd be curious to hear what happened.

I have had a few requests to start a thread on it. I guess I figure people don't want another blown ecoboost thread at this point, but maybe I will start a new thread later today.

its always nice to find out details regarding things like this. u should get the info out to the people who own the car.

You shouldn't have to even ask them what happened. Ford should be obligated to fully inform you.

Start the thread, we see the good.. We should also see the other side, so people can make a informed desision. There is alot of ecos out there and most have no problem. But if you cant afford to build a engine its good to be a little cautious..

Silver GT's experience illustrates issues other than LSPI, which is not as "common" an issue as people suppose.

Now I have a 2016 (built in May) with about 2300 miles, not to many miles yet. However I cruise often in 5th and 6th gear. I've easily generated boost into the 10~15psi range at those speed. I have the 3.31 rear end so my rpm actually spends most of its time in 1500 to 2250 range during normal driving. Could I suffer an LSPI failure? Possibly. Is it likely? No, because Ford designed the EB engine to prevent LSPI conditions from occuring.

Yes, their OEM motor oil has 2250ppm of Calcium, which is the primary contributing factor to LSPI, regarding oil. However engine design and fuel play a far more critical role. You can blow an engine at high RPM just as easily if timing, fuel and boost are not managed properly.

The EB motors have been around since 2009 in some form or another (starting with the 3.5L twinturbo V6). It would make little sense to be moving more and more of their products into EB motors if they were "dropping like flies". You see a concentration of the failures on the forums as that's where people vent frustration and search for answers if they can't get them from service departments or on their own.

IF you really want to see if it's an "epidemic" problem, you need to find a cited source with actual statistics breakdown of catastrophic EB failures that categorize them by cause. I'll bet it's less then 0.1% that suffer these types of failures.

Hype was built up because two cars primarily experienced these issues in higher numbers due to engine design (both of which were newer to TDI engine design). Oil factors in and can increase the likelihood, however it's not the root cause: MazdaSpeed3's and Hyundai Veloster TDI's.

Hyundai resolved their issues after the first year or so and the problems virtually disappeared. Not sure on the Speed3's as I didn't follow that much, however they were plagued with other issues as well such as the turbo bearing seals failing or leaking oil badly etc.

I was told at one point (however I can't find a cited sources on this), that Ford revised the wrist pin bolt due to periodic shear failures in 2015 models. This would explain some of these failures other than the LSPI hype. As stated, LSPI isn't new, high compression NA engines have suffered LSPI as well, even more tame NA engines have in certain circumstances. The coyote V8 suffered issues with oil pump failures, which as you guessed it, sized up V8's...while not as dramatic, still calls for a new engine.

From what I gather, these failures also seem to be much more common for 2015 low mileage than 2016's. Although you will always get failures of every year of any vehicle, NA, TDI etc. First year runs are usually the most prone to these types of issues as opposed to last year of a particular series, when it's the most refined in terms for production, quality control and small design tweaks.

Another case in point is the "blue smoke out the tailpipe" issue that several 2015's and even early 2016's have. It's due to a restrictive factory oil separator causing pressure buildup in the crankcase during extended idle which pushes oil out the turbo bearing seals. There's a TSB to resolve the issue by replacing the oil separator with a new high flow unit they designed to solve the issue. Takes about 1 hour.

Wrist pin bolts is far more involved, and a much less common occurrence. I do not believe they would put out a TSB for it nor would they announce any design revision, just fix it and for those that do fail, well they eat the cost assuming you haven't voided the warranty.

There is NOT a single documented professional source I can find showing LSPI failures in ecoboosts. Forum members speculating that's the cause isn't documented proof, unless Ford Engineering is calling them up to tell them that was the root cause they found. Now there may be a few LSPI failures, as it does occur, but this does not fit very well, especially with Silver GT's conditions which are NOT LSPI conditions...
