It happened cylinder 8! Now what?

[stanielz]

no disrespect. But i dont care if your the god of tuning. if this were true. Every dealer would have a pile of 5.0's sitting in the lot.

I talked to shaun @ AED and he explained it to me pretty well, because i had doubts too.

Theres a lot of contributing factors that lead to the lean condition at WOT. And a couple of things have to line up just right for #8 cylinder to go.

The factory tune has the lean condition but it saves itself by going into "protect cat from burning up" mode. That alone isn't enough to do it, unless its repeated under heavy loads many times i assume.

But when people get off road pipes, the "save the cat from burning up mode" gets disable via a tune. Also when people change out their clutch, the random misfire CEL comes up and get crankshaft profile relearn has to be done. If its not done, the misfire will default to a Stoich 14.XX afr from cylinder 8, i believe, even during WOT. These are all parameters that people didn't know about initially. And generally speaking wouldn't blow #8 cylinder. But with mods and driving hard and hot intake temps, #8 cylinder lacking a proper coolant feed, if it all lines up right, boom.

Thats the jist of what I understood. There are actual specifics to every scenario but i just got the general rundown.

I drive my car on the street all the time and race it on the street all the time. I was just being cautions. Nothing wrong with that. Ok my 11.3 that's fine, first time out with the car with a 131 trap. Take it easy? Really? Tell 2fst-4u to chill out and stop bashing a company on here every chance he gets.

Pull the covers over your eyes it's scary :/.

Thank god I'm ZKDO

ditto. my heart was beating with a 6/11 build date.

Hate it for you OP. May be some members here that have upgraded their engines and willing to part with their old ones for a cheap price. If you're going for forged internals, I'd go for the Livernois short block.

Right here. Id sell Rods/pistons/rings and bearings for $150 shipped. 22k miles on them and all looked really good when I took them out.

There you go! Good to see members looking out for each other!

stock is fine. again. if this was so common. there would be a tsb or recall. i dont care what people claim. the car stock is great.

Or a complete redesign for '13 &'14.........

respectfully disagree. blown number 8 have been reported with completely stock vehicles = fact

and like i stated before, (did you even read my comment attempt at a explanation?) a lot of things have to line up for this to happen, and those things are just really more IMPROBABLE to happen on a stock engine, but POSSIBLE.

In my area (which is mainly truck area) ive heard of 2 bone stock 5.0's looseing a #8 cylinder. One was a boss and another was just a GT.

When I first got my 2012, I talked with one of the region field service engineers about this #8 concern and he knew about it on several other stock GT's.

Interesting as to the car blows #8 on start up! never heard of this. Also OP was there mods done to the car after last tune or current tune that the factory adaptive learning couldn't or wasn't able to correct? I would still think that it takes a lot more than A start up to blow a #8.

I saw Steve mention earlier that the dyno tune was not done at BBR shop, So did another tuner try and tune it?

Does the mmr cooling mod help with this issue? I have it installed on mine just to be safe

Are you a ford tech?

so if he says no does that negate his whole statement? What Blazer707 said is true. search google. you'll find people post about it and their car first hand.

Girls post they are virgins online too. Most of you are living in another world. Its always fords fault when you dont wanna man up.

theres no need for insults here man. no one ever said it was fords fault. its how how the platform was designed. it just so happens that we choose to go against its design sometimes, or push it. to believe that a platform is perfect is naive.

if you get a brighter bulb, your light bill goes up, its not the the bulb manufactures fault.

were just trying to understand the issue, again why are you getting defensive and insulting?

 

[slamdcoop0428]

What I want to know is where is the OP at? This guy makes a thread in obvious distress from blowing his motor and asking for input. But has yet to make one post. Kinda odd if you ask me. You can only cry in a pillow for so long after blowing a motor.

 

[stanielz]

lmao. has anyone ever done that? i wonder...

but i agree, its a bit suspect.

 

[Shaun@AED]

Ford has been doing similar things for years.
Early 2000 F150 run Stoich at all times, including WOT. They NEVER transition to a rich A/F at WOT. We call them spark plug spitters.
