I am new to 03-04 Cobras, always been a pushrod guy.....

How do I tell if the driver side head has been replaced on an 03 to fix the head tick. Is it ONLY the 03 that has/had this issue?

Thanks!

Dan

Ive been told that the revised head is marked by a blue strip. I think you see it if you look to the side of the blower, right by the injectors :thumbsup:

I have heard that there will be a blue dot there. Also, it was mostly early production 03's but also some 04's have had the issue.

Any 03-04 Cobra can develope the tick. The blue dot is a myth that the head had been changed. I will see if I can find the article on this issue.

Mine has a blue stripe, dot, whatever on mine from the factory and has not developed a tick. I always keep my fingers crossed.
