Not to hi-jack the thread, but was it the tune that caused the #8 piston damage?

I read on another site that a sign of too aggressive of a tune on the 2011+ was #8 piston damage.

I am not sure if it was the tune or not. The company I got the tune from is very reputable in the mustang world and local to me. When they tuned it and it was on the dyno the A/F looked spot on.

They have hundreds of cars running the same tune I was running so like I said I can not be sure.

Here is a good long thread that has pages and pages of discussion on the failure. It is a good read.

2000SS1979 a friend of mine had a 2011 mustang 5.0 with 6000 miles on it. It had full bolt ons and a tune and he blew a hole in a piston as well. I think he was the first one in the country to blow his motor.

After a lot of fighting Ford finally gave him a new long block and took away his warranty.
He sold the car after having a lot of problems with it. He is now in a Terminator cobra.

WOW..FML

I had the misfire code and they did all kinds of stuff. It went away for a long time then it came back. I haven't had it for a long time now. They replaced tranny and everything.

I got the code when i got on it hard. And this was even on stock tune. What gets me is some having issues some not. The few that have some was bone stock as well.

Just makes me wonder if my issue is still there. Good to know they covered it though. Hopefully i have issue they cover mine also. After all I had engineers and all involved with my misfire code. 7 trips to dealer and everything.

What is crazy is the ones to seem having issues is manuals. I have not heard of any autos having issues.

Yeah my friends 5.0 was having the misfire code off and on before his blew up. I'd be worried if I were you man.

Did he ever notice loss of power with code? I know i haven't just wondering really.

I did not have a loss of power for about a month with the code coming on and off. Then one day bam the car ran like crap and had to have a new motor put in.

Just crazy. Mine has had issue for while. Haven't had code in long time. I am wondering if i should buy forged pistons now and have them put in. Kind of a in case thing and strengthen engine all at once.

yeah sometimes he noticed a loss in power and sometimes he didn't.

HMMM. I have never had a loss of power., I also found some guys with mis fire code was cause of clutch issues.

Good luck to you. Hopefully if it does break, Ford will cover it.

What is the cuplrit of the code and the piston problem?

ohioborn80

iTrader: (2)

Few things have been culprit for miss fire code. pressure plate coming lose causing vibrating in crank sensor. Compression drop or not reading in cylinders. The 8 piston.

Issue for #8 piston seems to be the rings are rolling over. Ford has said it was cause cars was modified till few was bone stock that it happen to. I think total list of cars that it has happen to is about 8 or so.

I think i will be screwed. They will blame on my mods. But have USAA they would cover under insurance. Did my buddies G8. Then I would swap in a Boss engine.

That sucks man, but since your car is down and mine is still sitting under a cover I'll run you in my work truck against the Avenger.

assasinator

if i ever have the misfire code one time its back to stock that day, and get some very easy miles on it before it goes.

i have 21,000 miles on the car as its modded now. never a code. i obviously drive it hard.

I think your work truck would have taken the avenger from a dig, a roll, mud bog, you name it. That thing was slower than ****.

But good news! I got my car back.. Time to beat the **** out of it again!
