So i had my truck at a Ford dealer for some maintenance and they said the check engine light came on while there and they scanned it and i had a misfire and loss of compression on one of my cylinders. and they might have to tear it down. The service tech then mentioned my Borla muffler and said there's a chance Ford wont cover it?! WTF is that?

I'd be extremely hesitant to let them do anything with it until I saw it in person. Taking some tech's word for it that my truck's engine magically imploded while it was at the dealer out of my hands raises a red flag to me.

The service tech is wrong. A cat back installed WILL NOT void your warranty. A tuner, on the other hand, could.

He asked me if i had it tuned and i said nope. I should know more tomorrow about the situation. its just really weird cause i have never had an issue with it

I an reminded of two things when I hear that your engine completely lost compression at exactly the time it was at the dealer:

1. Its funny how "fat chance" and "slim chance" mean the same thing.

2. There are actually two chances that the dealer did nothing wrong.........slim and none.

What "maintenance" were they doing to your truck? Would it have involved any possibility of leaving a washer or nut in the intake tract?

They were fixing under warranty a loose/wobbling steering wheel and a vacuum leak on my 4x4 system that was causing my hubs to try and engage. After fixing the vacuum leak they took it for a test drive to make sure all was well and thats when the check engine light came on.

Im not accusing them of any wrong doing thats not the point of my post . Im more concerned with the fact they said Ford "might" not cover it, reminded were still diagnosing but doesn't sound good.

Ignition coil / plugs....or something funky with the timing sensor??

There's a Ford service supervisor here on the forum, and I am sure she will weigh in here. There is simply no way, given the information you've given us thus far that Ford should be able to deny warranty coverage.

The Ford performance muffler is made by Borla and is the exact same system except it says Ford, not Borla.
