[QUOTE="9secondko, post: 11415312, member: 83742"] Sore to hear of your troubles. That's what it sounded like when I first read your thread. But I was hoping not. I had the exact same thing. The '03 motor had an inefficient head casting that provided inadequate cooling and the exhaust port design was prone to heating up and warping the valve guides. This created a valve "tick" sound and leads to compression loss. Sadly, all original engines share this flaw and it shows up at various stages of the engines life. Mine was bad. Two cylinders affected. I had wondered why the car shook like a crammed big block and had that strange sounding exhaust. Compression and leakdown nailed it. I was going to Get a valve job, but then I'm stuck with heads that run hotter than anything and the same issue will pop up again. Then I thought about buying new heads. Except, for the price of the pair, I could have a new long blOck for 2k more. So that's what I did. Anyone who didn't have the new head installed when the tsb came out... I don't know what to say. For those of us who bought it used, it really sucks because we bought a car with no way to have ford cover their problem. Long post. I know. But wanted to share in order to help you make the best decision. [/QUOTE]
