I had the tick and it was because I lost all compression in cylinder#8. They replaced the entire longblock under warrentee. Just in time for my new s/c. I actualy had my s/c in my kitchen all ready to be installed when the ticking started. Good thing I didint void my warrentee by installing the s/c before the tick started...

As far as i know the new Cobras have heat issues with cylinder #7 and #8. Not sure why my cylinder died.. they never told me. They wouldint have replaced it if it were from abuse.
I HOPE THEY STILL DOING IT BECAUSE MY HEADS ARE TICKING. sorry i didnt know cap lock was on. anyway they need to do somthing on a warrentied car, if the heads are damaging the engine, causing loss of hp, and causing loss of cylinder compression? what happens if you lose compression in a cyl. anyway, is your hole engne shot? or can you just replace some parts and be ok? im not a guy who knows everything about engines , but i love my car and i dont wantt to give it up. i will replace parts on my own if i have to.

- Try to isolate the noise by cancelling the cylinders, by unplugging the injectors one at a time (start with #8 cylinder).
- Verify that there are no exhaust manifold leaks.
- Check to make sure that the camshaft spacers are in place. If not, install cam spacers (per Workshop Manual Section 303-01C) and retest vehicle.

Ford Motor Company told dealers that 4.6L 2V engines built prior to 29 September 03 and installed in 2001 through 2004 Ford, Lincoln and Mercury vehicles may have defective cylinder heads.
The engines were installed in:
• 2001 - 2004 Ford Crown Victoria, Mercury Grand Marquis and Lincoln Town Cars
• 2002 - 2004 Ford Explorer and Mercury Mountaineer
• 2001 - 2004 Ford Mustang GT
• 2001 - 2004 Ford E-Series Vans
• 2001 - 2004 Expedition
• 2001 - 2004 F150s
According to Ford, the 4.6L engines "may exhibit an engine tick noise that is present at all temperatures during idle. The noise may be emanating from the valve guide area in the cylinder head. The noise may be more prevalent in the front wheel area, any may not be heard with the hood open."
Unfortunately, Ford may not notify owners of this action and will only perform the service to those who know what to ask for in order to get their vehicle fixed. It's part of Ford's secret warranty program - a.k.a, "If you don't ask, we won't tell."
