Hey guys looking for some advice on my car. Its an 03 cobra 10th anniversary, just clicked 17k miles. I bought it last august and just started driving it hard this year. I started to notice a tick in the top end(sounds like) and im afraid its the dreaded head tick but i cant be certain. Any advice on finding out what the issue is? Also if it is the head tick, whats the best route to take keeping all the stock internals?
