Ecoboost Engine Blown?

[richard0ne]

guess Adam can't say one of his tuned cars hasn't blown anymore. Really would like to know why Joes Motor blew.

And no I don't believe his tune was the problem.

Just from speculation.. this a tough one.

Looks perhaps Joe's engine was was making more boost than normal at low RPM and the engine pre-ignited when he stepped on it?

In stock form, this probably wouldn't have been as catastrophic but with a tune with the timing changed, direct injection motors can def. pre-ignite and blow itself up..

Or, could it be a factory defect and Joe now has to front the bill regardless since a tune was present.

I feel bad for the OP and Joe and that is why I don't tune the car. I would hate to front the bill for a factory defect that wasn't related to the mods. However, at this point.. only tearing down the engine can see what exactly happened.

I totally understand and as an Ecoboost owner, we just want the car to be fun and fast.. One of the main selling point of the EB is that the car really responds to tuning, mods. Now in actuality, it could even thought of as a ticking time bomb once modded with no warranty to boot.

I'm sadden by this since the internals of the EB is pretty solid from factory.

Please explain whole piston rings theory

My understanding is 'piston seating' refers to the ring sealing between the cylinder/cylinder liner and the piston.

All new rings have a certain number of imperfections (ridges, flat spots, etc.) and that is what I refer to as a manufacture defect.

1. The rings need to be properly "worn in."
But I claim that this should happen even if the engine did nothing but idle (we're only talking about rings here, don't go off on me about how the turbo, etc would hate to idle), granted it would take 10 years of doing nothing but idle 24/7, but still they would wear eventually..

2. The cylinders need to coke up properly in order to reach a proper compression in the cylinder.
This should happen in any type of driving as well, even low load situations, should it not? You will get carbon deposits.

3. You have to have some full throttle situations in order to get high compression (due to the added air the turbo provides) therefore keeping the rings mobile and allowing them to do their job.
But then this wouldn't be a break in procedure, this would be a lifetime procedure would it not? You would have to keep the rings mobile by driving the engine hard once in awhile.

very sad myself and why I want tune mine, add cai, intercooler or exhaust, leaving 100% stock as its not the only 1 to blow in some way or fashion.

What smokes pistons and blows rods through the block is too much pressure on the piston at the wrong time inside the cylinder. Many ways to make that happen if things are not tuned properly.

Greetings,

I have been following this thread closely for about 3 weeks since our Ecoboost blew up, I just want to say that engine trouble does not necessarily come from tune mods, the only mod on ours is a MMR CAI, when the bearing spun I was in Track mode, Shift in Sport and launched at 20 psi of boost. I went shifted threw 3 gears, shifting at 5300 and then shut down, got home and heard a deep knock from the motor. Called Ford Roadside and they sent a tow truck and took it to the dealer. They repaired it with no hassles over the CAI, Interesting thing is the Service Adviser said the replacement short block is a new part number from the original, he thinks Ford may have found a problem with the original blocks and has done an upgrade. If I was these other guys with the blown engines I think I would push Ford a little harder to prove it was the tunes and not bad bearings or rods. By the way the dealer re-installed our CAI with even asking.

yeah thats what scares me as mine is a early build

 

[fastertoo]

Ours was a Special Order and built on January 23rd, delayed 3 weeks because of the fuel line issue.

It would definitely be interesting to know whether Ford has modified the EB blocks since their inception.

P.S. It took me 6 wives to find this one, she's a keeper. Merry Christmas all

I only have 2 more to go to catch up

I'm not sure a new part number could mean that a defect had popped up...obviously possible and maybe even likely, but even a simple change of vendors for a small part would likely change a part number. I think.

What does this have to do with rod being broken really nothing. Coking up don't understand where you got that. You meaning carbon packing if so you don't want that engine will use oil because it polishes cyl taking crosshatch machining marks off from honing . Mobile you mean rings not stuck in piston grooves.

Same thing goes with running engine colder like some tuners like to do. So they can crank up the timing to get more power. But cyl pressure are higher can bent rods that way too. Rings will not break in/seat because now piston and cyl not up to temp. You do realize I'm tech

 

[Elapid]

How many of the blown EB engines are auto cars ? and were any of them PP auto cars ? If I read correctly only 1 of 3 was tuned, 1 was cai only, 1 was boost max pedal max cai and unusual maintenance items immediately before it went? Sorry to all it happened to definitely make me nervous.

You're right it has nothing to do with it.. I have heard conflicting ideas regarding the engine break in period, whether or not one should drove it like you stole it or drive it casually.

i was just referring to the piston rings seating/sealing correctly when the car was from factory.

I wish I was a mechanic so I can know more and learn how to fix engines, etc.. I'm just a hands on guy that will try to do as much as possible without going to a mechanic

So what do you think happened to Jason in your opinion?

Regardless, it's a sad situation and if my engine blew up with no warranty, I would be hella down about it.

Mattrix (op) - No tune (had a tune, took it off), JMS boostmax, pedal max, MMR intake
Joe_Stang - Tune, MAP intercooler, Catless down pipes, MMR intake
Fastertoo - MMR intake

So I'm not sure if it's tune related or not :shrug:

But I will say this though, all three had a MMR CAI!! WTF?!

Part numbers change constantly. It's not an indication that any actual design changes were made. Your service adviser knows nothing more than anyone on this forum does, Ford does not release information regarding internal component changes to dealerships unless they are directly addressing a known issue via a TSB, SSM or FSA.
