Hi... I have what i described as a ticking sound between 2,000 and 3,000 rpm. People told me to check my headers or header gasket. I took it in and discovered a cracked header. I'm just in the process of having new ones installed, so I don't really know if it's going to get rid of the noise or not, but I'll let you know.
If nothing else I'll have a new set of hennesey headers...lol
