Hi guys , I have a 2004 g35 6mt, after a 10 minute drive or so when I am at idle I hear almost like a knocking sound. it only happens after a long drive and at idle. When the car starts cold its fine and when im driving I do not here any knocking. If I leave the car knocking while at idle for about 15 minutes it stops. What could this be??
