Here is some information for you. Ford service techs should have the service bulletin about the 03 head tick problem. Also, here is some links that may help.


According to Ford Motor Company Memo, 2003 Ford Mustang Cobras may have defective cylinder heads. The memo noted that the Cobra's may exhibit an unusual engine noise (Tick) that is present at all temperature ranges during engine idle.The memo also states that the noise may be due to bad cylinder head valve guides in the left hand cylinder head. The noise may be heard at the rear of the left hand cylinder head, thought the left side exhaust or at the left front wheel of the vehicle.

If your 2003 Cobra Mustang exhibits this condition, Ford may replace the cylinder head and cam assembly. The replacement cylinder head part number is: 3R2Z-6049-GA. Owners are advised to have their vehicles inspected before the warranty period expires.

This is considered a "silent recall" where upon Ford may NOT notify owners of this condition.

Should Ford Motor Company dispute this report - either someone from Blue Oval News or Flat rate tech will be more than happy to engage in a three way telephone conference.

is there any long term damage if the "tick" is not fixed?

It is my understanding that the guides where drilled on an angle so yes it will where the guides out :D

I have an early '03 that (mercifully) did not have the tick. Quite awhile back I called the folks at SVT and I was told that it is pretty easy to hear and affected a relatively small number of cars. The key point also made by paratrooper82nd is that the tick is heard at all temperatures. The engine in my car is noisy when cold. I was concerned at first but the noise goes away when the engine is warm. You may want to get an experienced ear to listen to your car. Personally, I would be reluctant to let a dealer act as judge, jury and executioner.
I hope this is helpful
