Motor Let Go Tonight

[Fast64ranchero]

There's probably alot more that did not post about it. I for one did not post it because this forum for what ever reason likes to make excuses. I lost mine on a first to Second shift WOT, shifted at 6,000 rpm, grabbed 2 gear and boom #3 rod out the pan, My car was far from stock, and I'm not blaming anyone but myself.
IMO it's a fatigue issues. My build date is 3/15

It all boils down to if you can't afford to fix it, don't mod it!

Don't jinx us bro lol

I'm hoping we aren't. I know it's gonna happen with modified engines, but at the rate these are going recently, it's a bit discomforting.

Thank you! Finally some truth. No excuses, no trying to "well you were doing this" analogies, no bullshit. From bone stock to modded/jms/pro tuned to auto to manuals to WOT to passing in 5th gear...these turbo 4's are blowing up.

Mine has a build date 3/15. Fck.

Looks like the price of the engine has dropped from $3,500 to $2,600-2700 depending on performance pack.

That's cheap as hell for a brand new assembly.

[MENTION=15289]ECM90[/MENTION], thanks for the link and mention of the price drop. I think I will pick up parts to retro fit the sub into my trunk. Very cool. Sorry to interrupt this discussion. Just wanted to thank ECM90 for the link.

Reading through this, heavily raced, flogging the car, modding to far or an actual FORD OEM engine problem. It does bring to light that the sport of modding our cars can cause an out of balance problem somewhere else we are not aware of. We are counting on each other for experiences along with the engineering and thoughfull designs by the vendors we choose to work with. In the end, how much risk we desire to take has to be a personal choice. I hope the OP can get his ride back ASAP.

For the rest of us, I agree with others that a sticky people can post to would be great to build up a small DB we could reference. I think posing to that sticky, a certain set of information needs to be required for the post to stay. What mods, tunes.. You guys can name them better than I could.

I imagine that getting people to post the root cause of the failure would be difficult. I'm not sure if a post op is always performed in the same way with the same level of automotive engineering back ground to make a non biased root cause determination.

I don't blame Adam for this at all. I thinking this was already hurting and it decided it didn't want to take anymore. I went in second gear. I do not abuse this car as much as Adam said on Facebook. The car is basically babied during the week. Some weekends i take it and have some fun. Other time it just sits at the house. And yes i needed to do some revisions as i haven't in awhile. My computer took a shit and had no way of sending him any. But yes, when i would make a pull it would see a spike around 27lbs. But it wouldn't stay there. its hit 27 for like a millisecond and stay around 25 to 26lbs.

I'm not trying to scare anyone or blaming anyone. This car has been through alot. Maintained, changed oil every 4k. Before it blew, it didn't have a any oil in the throttle body or anything. Of course it does now. Cylinder 2 let go and went through the bottom of the oil pan. I have huge chunks of the oil pan laying around. The oil drain line for the turbo going into the block ripped a big chunk of the block off. Hopefully the mechanic that's taking the motor out will get me some pictures.

What's the count on this forum for blown ecoboost motors? I was trying to add them up but lost count. If we have the number of forum member and the # of blown motors we can come up with an odds, haha like if you're on this forum you have a 1 in 1000 chance your motor will blow...

Anyhow, sorry for your loss brother. Hope everything pans out. At the end of the day it's just a motor. Worse things can happen in life. Good thing is, the engine is only around 4 grand (if Ford won't fix it)....unlike the expensive coyote engine!

There's a reason that you're seeing the blown motors on this forum, it's because people mod them. 27lbs of boost?? Come on, you're running on borrowed time.

99% of the people on here who have engine failure have modified their engine/PCM, and unfortunately you always run the risk of a failure when you start modding.

 

[murphy]

Of course the percentage is high here. Most of the members here are enthusiasts. And enthusiasts mod their cars. I spoke with a local service advisor and that particular dealership has had 3 incidences and all 3 were bone stock. And the service advisor told me one was an auto convertible owned by an older couple that could of cared less about performance. They just wanted a Mustang Vert that was economical.

im leaning toward this as well.

Ya which is why I said odds of motor blown of ecoboosts *on this forum* and not the odds of any ecoboost motor blowing.

Either way, one of these blown motor threads *another one bit the dust* post #70 is a had a Ford tech and he said of the 6 blown motors that have been in his shop 4 of them were NOT tuned and completely stock. So the motors are blowing on the non modded as well. We just don't see that data because almost everyone on this forum is modded so we just see that data. So to say 99% of them are modded is a stat taken from a forum that has 99% modded...so same fallacy.

In a stat taken in a non biased environment such as a ford dealership granted its only one shop the stat is 66.7% stock blown motors and 33.3% modded.

According to Murpheys post that dealership has 100% stock blown motors.

And that's all heresay. 6 Blown STOCK Ecoboosts? I don't believe it. 6 blown STOCK engines at a single dealer would mean there are thousands blowing up nation wide, and that's simply not the case. Do technicians have the ability to contact engineering and run the PCM part number and calibration to determine if in fact the tune was factory? The answer is no, they don't. So if the owner tuned the car soon after it was purchased, the key cycle PID will look legitimate. In which case, the dealer will assume it is "stock". Each dealer has a different idea of what "stock" means all well, they don't all play by the rules.

The guy from that dealership was the Service Manager, so I'd lean towards him knowing what he's talking about. The flash counter is what's gonna show up. The key cycle is easy enough to fake.

Flash counter? Please do tell more....

Your's is heresay. Your claiming 99% which is not even the case on a forum that is mostly modded. There have been members on here stock with blown motors. Let's just say 1 stock for arguments sake that means you would need 99 blown modded motors on this forum to satisfy your bogus 99% stat.

I SAID OF THE 6, 4 were stock. Only one had a tune. This is from a ford mechanic that works at a dealership and sees these first hand. So I don't know why that's considered heresay, it's taken from a quote from this forum from a ford mechanic himself. Why would he just make up the number and have all this information on each one. He had a whole write up on it and included very specific details, they were all automatics.

I started a thread here
http://www.mustang6g.com/forums/showthread.php?t=49520

Lets get a database set up.

I'd like to know if it was the Piston or the rod that let go.

I'm guessing it's mostly the pistons letting go first allowing the small end of the rod to go wild. Cast hypereutectic pistons are extremely sensitive to knock and any small manufacturing defect will cause them to be even more brittle.

Rods snapping is on stock motors seems more a function of LSPI (aka as Super Knock).
Since it seems it is always Cyl 2 and Cyl 3 letting go it supports the theory that this is an oil related issue as on most ecoboost engines those are the ones with the most oil coating due to pcv.

I'm not an engineer, I started studying engineering but switched to IT after a year so I do know more than the average person and alot of theory, but real world experience is lacking. For that I am in contact with my old professor who was an engineer at Opel (GM I know but I don't hold it against him.)
He has given me a few charts that are enlightening as related to Early Ecotec failures.
I'll put them in the other thread and would like the tuners who have loads of real world experience to chime in.
