anyone ever experience head gasket issues on their 4.6? according to 3.8 forums, it's common on their engines

are they stock mustangs? the problems I've heard regarding head gaskets usually applied to people who tuned up their cars. perhaps the 3.8 head gaskets can't withstand the heat of the additional power?
 
You wont have any problems with the head gaskets on a 4.6. Unless you bore out the motor too much then you can run into issues.Reason why some big bores arent recommended with Forced induction. The cylinder walls are just too thin and you risk the chance of blowing a head gasket.

yes they're stock... there was nothing worthwhile for them to do to them

my friend's mustang has a major transmission failure and he believes it's because of the chip that he put in his mustang. according to the ford dealer that repaired it, they said that his pcm was completely destroyed and that the car was trying to change to gear 1 and 2 at the same time.

does anyone know anything about this? i mean if it's actually possible to take out a car's transmission with a chip?

BUT it can plug your cats much sooner...and besides it is foolish to run a more exencive gas than you have to, there is no point.Will cost you all the way around.

:rlaugh: LOL :rlaugh: ROFLMAO :rlaugh: What the ***K are cats? I don't think I have ever heard of a mustang with them. J/K Also, I swear up and down, on a bible, whatever that I get 4-5 mpg better with premium than regular. This is based on 100% highway driving at 75 mph for the duration of the entire tank. And it was not a one try die deal, I have tried it 3 timers with each and I get 4-5 better with premium every time. I have to drive on the interstate through South Dakota for 390 miles, I really use this gas mileage thing as a fun goal I set for myself.

IF you have a manual, you wont have to worry about that. Get a good Dyno tune or burnt chip and your tranny will be fine. Depending on how much power you are putting to the ground of course.

How did the tint ruin your window?

I think it was a short in the defroster. Upon looking at the shattered glass it started close to that metal piece where the defoster hooks up and spread all the way across the window. Good thing the tint was there because that was the only thing holding all the shattered pieces. The first dealership I took it to denied my claim. So, I took back to the one where I purchased the car and they covered everything was about $1500 bucks in charges if I remember correctly.

Did you just happen to use your defroster for the first time at 8,500 miles? Or did you use it over time and then your window shattered?
