Melted Piston!.... Engine Block Swap

[SHOsc]

I usually run 89/91/93 whatever is available. I travel the Carolinas/Virginias for work, so there is not one station i frequent.

I am slightly concerned that i have not spoke with a regional/district ford rep yet. All my info has come through the service manager. There seems to be ZERO urgency. Reminding me of Government Motors.

Right now, they are breaking down the motor. From there, they will have the official go ahead on how to proceed the fix and hopefully estimated finish time.

Are these cast or forged pistons?

 

[86si]

I would be surprised if they were forged.

 

[wchain]

The pistons are Cast Aluminum.

Good phucking god. Enough with the 89-95 V6 guys preaching in the Gen4 section. We know, you like your V6 NA engine. We know, you will ***** and complain about Ford needing to release a new SHO, then complain when they do that it is not a 89-95 V6 with a manual, even though you are not the target demographic because you are too po' to buy one.

Jesus, STFU and get out of this section if you hate the ecoSHO platform so much.

thank you randy although i do love the v6
i can appreciate it as a car guy not only as the ecoboost in the sho but as it lies in many other vehicals imho i think they hit the hammer on the head with this motor design and NOT AS JUST A SHO MOTOR but as a step forward in automotive enginiering

I really doubt it. When you look at the engine's operating temps, and the temp of the intake charge off the turbo, 101F is nothing.

Besides, the one thing that all of the mfrs do is serious (very) cold weather testing, as well as very hot weather testing. They are all over AZ and eastern CA around Death Valley in the summer.

You could run the car without the intercooler. Power would suck, but you could do it. The PCM can adjust for about any of these conditions.

Except when something screws up. A failing injector has more serious consequences in a forced induction engine.

While I'm not an expert on gasoline engines, I make my living repairing diesel engines so I would have to agree, at least with the part about failing injector.
My guess is the injector failed in some way, either plugged up orfice in the tip causing improper spray pattern or the tip is missing completely. I can't tell from the pictures but was there any cross hatch left on the cylinder walls, or does it look like a mirror from being washed down with fuel? Hopefully they check the injectors to make sure it didn't loose a tip because if it did, it met up with your turbo and I promise they did not like each other. Just my $.02

In case you hadn't already figured out, I'm new to the site. Just trying to help

No updates?

I think I love you.

Funny you guys mention Direct Injection, Why the Pistons look so dirty, and Audi all in the same thread.....

dirty pistons+even worse heads/intake ports/intake manifolds/+Audi= Direct Injection

that same equation holds true now if you remove the Audi word and place ECOBOOST there

change you oil fast to boys, Oil experts on VW/Audi's are saying they would run some of the best synthetics around for a thousand mile oil change interval........ These motors sound good on paper, but they are VERY dirty, rough running machines with some miles on them. They need constant motor cleaning, best way is through an intake port so that it helps clean the manifold and head/ valve areas.

I suggest you all do some research in other car communities that have been suffering with Direct Injection for years now. Just so you know what to expect. Your 2.0's VW/Audi is a REAL good place to start

this one isn't too bad, its a Porsche cayenne.... I've seen MUCH worse!

I assume this pics are looking down from the top of the intake valve but this makes no sense.....the intake charge is dry with DI. Were these folks running PEMEX or well head gas? I've been driving a MINI COOPER S with DI for 2 years (using only name brand 91 octane (Chevron or Shell) with no problems whatsoever.

 

[hawkeye18]

I would surmise that in a regularly injected car, the fuel, being highly energetic, acts as a detergent and cleans the valve stems/valves as it passes them. In a DI motor there is no gasoline to thin out and clean out the varnish that builds up from PCV systems, etc.

Can you imagine all the s*** that builds up in a V6 SHO intake caking around the valves if there wasn't fuel to clean them off?

 

[luigisho]

You think that's bad, you should see the gunk in GenIII's.

 

[SHO U UP]

Holy cow 32MTX! Thats out of a Cayenne?!? I'll have to show my wife that pic and tell she'll have hands full when she gets one. I can't believe that the DI would cause all the mess, no matter what make or model it is. I can understand the philosophy of why it happens, but damn. That is unreal. I wonder what steps Ford will do when the engines get near the out of warranty segment and crap starts acting up. Which, at this rate, may even be before the 60,000 powertrain warranty expires.

Well, here is the update...

I am being told that the root of my problem has come from a spark plug....
The tip of the plug broke/or melted?...which then caused massive damage to the piston/cylinder/head.

Ford will being doing a long block replacement. They will be sending a new 2011 motor off the Assembly line by end of the week. I am told i will have the car back a week or less after they receive the new engine.

It was also recommended that i use premium grade fuel until new plugs come out..?

That's all i know.... Do i get my odometer set at 0 for new motor?

So are they are saying cheap fuel causes detonation and cracks the current OEM plugs?

Not that I have or want to run cheap fuel.

So will there be a TSB to replace plugs in the Ecoboost engines?

Looks like we're going back to old "decarbonizing" maintenance requirements from the
'40s and '50s. How else could you address this build up problem on a DI engine short of a periodic tear down?

Seafoam into an intake port!
