Default 2012 5.0 #8 failure?

So I did a search and didn't find anything on this, does anyone have any input on the 2012 5.0's? Eco-Boosts are rumored to having some issues with the plug porcelain breaking and falling down only to trapped by the "J" strap resulting in preignition. Maybe the 5.0 and Eco-Boost share the same plug and therefore the same problem, just a thought.

There is an issue with the #8 cylinder faulting.
Just a few threads down from this one is the subject. Its titled TSB something #8 cylinder failure.

I have heard NOTHING about the #8 cylinder fail on the new 5.0's being due to this.
Ford it stating it has to do with mods being done to the car and also aftermarket tunes.

But some people are saying it has happened with stock vehicles.
Again never have heard of it being due to a breakage of the plug with the new 5.0's.
Plus the cylinder head of the 5.0 and a V6 should be shaped differently.

Sorry man, but you couldn't have searched to hard. That's been the top of discussion for 2 weeks.

Actually I did do a search for 2012's and this issue and found no matches but a search for 2011 did show the above mentioned thread about the #8 piston failures. I looked through all 10 pages and didn't find any mention of a 2012, maybe I overlooked one. If not, maybe the 2012's have a different strategy where the knock sensors are concerned.

There were no 2012 engine changes, so all 2011 engine issues will apply to the 2012 just for future reference

You should know though, that issues with the #8 cylinder are seemingly pretty rare even among tuned mustangs. Actual materialized examples are few and far between, however discussion over the threat of Ford invalidating warranties is abundant.

The only thing I have actually heard about #8 piston filure in the Coyote is a TSB issued by ford, TSB-11-07-07.

http://mustangforums.com/forum/5-0l-...n-failure.html

Just as mentioned above, I have not heard of an actual case happening. Hell, I must be hiding under a rock because I have not even heard about it on the internet.

There's someone going around making wild claims about his #8 and how Ford is blacklisting him, but he's all over the map with his claims, first was his car was stock, then not, then all sorts of FUD about engines having rings put on upside down... Can't believe a word out of this guy "19cobra99" myself. Typical troll posts, in my opinion.

Where did you hear Ford was "blacklisting" him?
And what are you referencing this guy too? I dont see "19cobra99" in the thread you linked anywhere.
Where did you get his name from? Is there a thread you can link with him in it?

I wouldn't say the guy got blacklisted, but his warranty was definitely voided. Also, don't believe anything the guy says bad about ford. He's been making up rumors and editing posts. He admitted to having a tune on the car before and returning it to stock after he had a problem and taking it to ford which then did extensive research to void his warranty. Honestly some of the research was incorrect, but his warranty is voided nonetheless.

Very complicated stuff.

Even if he did lie if he went to court they might say ford had to prove that the tune caused the failure to the cylinder.
BUT even if the 5.0 can't handle aftermarket stuff well.. which nobody wants to hear... they could very well prove the tune is what caused the cylinder to fail, even though it failed because the engine cannot handle aftermarket mods well all the time.
Even if the car is not built to handle mods like we want it to.

I wonder when all is set and done what we will find out is causing this problem to happen.
think about it though... even if the tunes are causing it to happen, if ford built a motor that could not handle aftermarket mods well that is their right. They dont' HAVE to build
a car to handle aftermarket mods.

Which again I know no one wants the 5.0 to be a car that cannot handle the aftermarket mods well.

But this is interesting due to the fact that so many 5.0's are runnnig fine and right now it seems to be a small percentage with this problem.
That opens up a whole nother can of worms.
WOW. This is just too clustered right now to tell what we will find out about the 5.0 in the future one way or another.

I'd say in the end Ford has the upper hand. The only thing that would go against them is if stock engines started to do this, and they might have some trouble then, or at least the
customer of a failed motor would have an argument, even if it was still a losing argument lol.

In the end it may end up so that most 5.0's do run fine... but there is MORE of a risk of something going wrong than with other Mustang engines
and people have to take a little more thought into deciding whether they want to mod or not.

I see you edited your post. Pretty sure everything you needed to know was in that link I posted.

Yup it was. He did change his story a good amount of times.
He also claimed Ford had a video of him racing and he claims it was of a different car.
He also claims they have him "talking" to someone about a laptop problem and he said that was before a tune. Which seems he just busted himself admitting he did have a tune.. lol.
Furthermore.. I don't see why Ford would put up evidence of a different car. Seems like they would make sure there evidence was legit.

He must have a lawyer already if he claims Ford has evidence against him, because there's no way Ford would tell him about that before a lawyer. At least MOST people would not divulge evidence so that people would have time to gather a rebuttal even before having a lawyer.

MOST of his story could be B.S.
I don't know why he would lie instead of just trying to rely on the Mag act to
build his case on. That is just STUPID. The mag act would be his real weapon. Lying just hurts his case.

Now again the question is did that tune actually cause the failure.
But also again his lies would NOT help his case.

This guy went about this the WRONG way. I can tell you that for sure.

I talked with Brnespeed regarding my Stage-1 Kit, and they had vaugly heard of two potential instances, one with a stock motor and one modded ( I do not believe by them). Both were eventually covered under warranty, but no specifics were available. My sense after the conversation with them is that they are not considering releasing a milder tune until any evidence points to the mod as the problem. Ford is attempting to cast blame in that direction, but there is no evidence, according to Brenspeed, for that claim. Until there is, it is business as usual.

They are still running their two test mules with 93 race tunes, and so am I with zero issues. I drive my cay like I hate it, with zero problems @ 7,000 miles. Not a drop of oil usage, nothing. I am continuing with the race tune, although I am careful to stay with Chevron from a reputable branded station.

They did say if you are losing sleep over it, load the 87 tune & forget about it. Otherwise, accept the fact that modded cares have a bit of risk associated with the fun.

The problem with taking issues like this to court, is that it would be a Ford engineer and lawyer vs. you (and possibly your lawyer). The burden of proof unfortunately ends up falling on you, as look at it this way:

As an unbiased judge, who's story are you going to believe? The engineer who brings all kinds of data to back up their claim of failure (data which may not even be relevant, sadly - I've seen far too many engineers claiming air filters cause a swirling effect to the air which causes lean conditions...), or some random consumer who modified his vehicle?

I don't think a lawyer would even take a customer's case in this situation. The amount of research needed for $5k - $6k of motor work? You would probably end up paying more for the lawyer than the dealer work.

Personally...Just my opinion but people with really elaborate stories that post on the internet and then disappear are Trolls.

Jmatero comes to mind with his issue about the Ford Tranny problems he was having and about setting up an ABC 20/20 thing. I did a search for him on the interweb and he is registered in everything from Dodge forums, Chevy forums, VW forums, and others. Never has more than a handful of posts, then disappears. Probably diggin in the forums to find an issue then makes up a story to get the board riled up.

That in my eyes made him lose total credability.

Further research and the guy is/was en engineer in California so he's probably looking for a payday or to make a name for himself.

I posted some very specific and simple questions in his thread a couple of times about his info and proof and he never replied to me. Everyone else who was up-in-arms he was more than happy to elaborate further. Zero credibility.

You're not kidding. He's a member of at least 10 different kinds of vehicle forums. Honda Fit, VW, RX8, Dodge, Corvette, etc.

Are you guys serious? I'm a member of 8+ different car forums, easily. I've owned many different makes and models, and even signed up to browse forums of cars I was considering buying, not just one's I owned.

Making such strong assumptions with such little proof is silly.

But did you post about 1 issue, and only 1 issue? This guy has been everywhere trying to start some kind of anti-Ford MT82 posse, including on blogs and on blog posts that have nothing to do with the 5.0 transmission.
