This is a very hard thing to describe. It is at its loudest when the car has sat for couple hours + getting worse by the hour it seems. So...I wake up this morning start the car. Sounds fine. get it in first and give it gas the engine makes like a....clicking / metal on tin can tapping noise. Let off the gas and it makes noise as it drops down the rpm band. Give it hard gas and it sounds worse. This happens for about the first 5 minutes of driving. Then it dies down slowly until its barely noticeable. But sometimes its still obvious after driving 30+ minutes.

07 g35 coupe 6mt.

Any help would be greatly appreciated. I'm going to try to do some more research on my day off.

 

Check your oil

 

Hmm, i'd check with your dealership, your 07 will still have warranty.

 

our 6mt transmissions are notoriously loud...they make chatter and weird noises...it could be normal
