1 yr later, any crushed intercoolers or bad turbos?

Oddly enough, I don't believe that the turbo's are going to be the primary potential long term liability of the EB engine. I think that it is going to be coking of the intake valves at 90-100K miles. VW is beginning to see it in the 2.0L turbo DFI engine (and will probably help the customers with the cost). What happens is that anytime you have exhaust gas recirculating, you will have oily residue being deposited on surfaces. When it gets deposited on a hot surface like a valve, you will get coking. The problem with the DFI design is that since the gas is directly injected into the cylinder (instead of the port), the intake valves never get "washed" to remove the deposits. I sure hope that Ford has an answer for this. It is not a completely new problem.
The 3.5 Ecoboost does not have a mechanical EGR system like VW(or Audi) does in their 2.0. The VVT(not the turbo thing as stated earlier) EB uses cam phasing in place of a mechanical (and prone to have problems) EGR. Athough carbon build up may be a problem with these engines because they are DI, you cannot compare them with VW's engines due to the use of different technology.

The turbo's on the 6.0 were covered for 100K miles...so it should have been covered under warranty...mine was for $100. Mine blew an O-ring causing the turbo to ingest antifreeze. Looked like a blown head gasket out the pipe. They replaced the turbo and had it back to me the same day.....FiveStarFord Rocks!

Interestingly, I noticed yesterday when I had a bunch of snow all over my truck from driving in a snow storm that the front intercooler had about 50% blockage due to ice on it. Just water/slush from traffic in front of me that probably got stuck on there or it melts when snow hits it and then freezes quickly when ice cold out. Obviously I didn't notice a drop in performance or anything. The next morning it had thawed off inside my garage and no issues.
My thought is that it is so cold, and even with ice built up on to the cooling fins it still has really cold air coming through...just blocked a bit? (which I know is the HUGE debate about putting a grill or screen in front of the intercooler in the first place - blockage).
If it happens again I will take a picture.

Regardless of what ends up being the Achilles heal of the EB, if ever there is one, THAT will be the "I told you so" problematic part that everyone had warned us about! Lol! I say enjoy them if you chose one like myself and IF that day ever comes, deal with it the best you can. If that's not what you want as a possible scenario, then don't buy an EB! Personally I love mine and having a lifetime powertrain warranty doesn't hurt either!

Well said! It is funny to see so many people (some Ford owners too) wanting this engine to fail. It is like they are salivating at the mouth waiting to pounce at the first problem this engine will have. What is really funny, is that if this engine was a diesel (like it was designed and built like - Link), then I doubt there would as much talk about reliability and all the Ford naysayers probably would have bought one.

Al-Kohalic, Good find on that article. I see that EGR is a planned addition to the Ecoboost. That will be surely criticized as it already has been in this thread. As in the VW engines, if I'm not mistaken, EGR is used in their small displacement diesel engines and not in there turbo gas engines. Correct me if I'm wrong on that. But that being said, the oil build up and bake problems shouldn't be as big of a problem in gas engines. Seeing as how the starting "fuel" source is not as heavily "oil based" to start with. I'm not an idiot that thinks gas doesn't come from oil, I know it does. However, we as vehicle enthusiasts often refer to diesels as "oil" burners, which in essence is what they are. Without getting into what most all of know on this site about gas versus diesel, gas burns "cleaner" which would leave less residue. Am I correct in assuming these things are true?

The turbos in the Powerstoke 6.0 (International VT365) where VGT not VVT. VGT turbos are not junk, they were just junk in the 6.0 do to the "shortcuts" International made when designing the 6.0. That coupled with the EGR system just made for problems after problems for a lot, but not all 6.0 owners. Cummins (my old employer) has been running VGT turbos in their marine and other platforms for years without issues. BMW and Porche have been running VGT's without issues as well.

Due to the regulated(forced) use of ULSD(Ultra-Low sulfur diesel), diesel is not as "oiley" as it used to be. You are mostly right that a gas engine burns "cleaner" then a diesel, but the modern clean diesel engines have come along way from the black smoke bohemoths they used to be. Diesel fuel has more energy content then gas, leaving most to believe that there is more left over after combustion. However, due to that fact that a diesel uses compression to ignite the fuel, it uses or burns up more of the fuel injected into the cylinder then a gas engine would. Allowing you to essentially do more with less and leaving less unburned fuel to build up.

I believe Ford programed your turbos to explode around 15 miles past your warranty expiration. I may be wrong though, I need to ask Loki to be sure.
