Hi all. My 2004 hemi is making a slight noise sometimes. I have searched and a few others have described it perfectly....it's a slight tick and/or escaping air sound that I only notice when I'm into the throttle a bit. If I ease around it does not make this noise. If I get on it a little bit it is fairly noticeable outside the truck or with the windows down. I have read about the hemi tick and am fairly certain this is not what I am hearing as I cannot hear it at idle. I have also read about the exhaust manifold bolt issues that many seem to have and feel like this is likely the issue. I am going to crawl under and try to pinpoint the sound and have a look around and if I can't I will probably take it to a mechanic. My question is if I need to replace some (or all) of the OEM bolts is there a quality aftermarket kit out there? I have heard of folks using bolts from Lowes and so forth but I would like to know if there is a high quality bolt kit readily available. Thanks!
