When I start it up of the morning it has a clicking or tapping I hear it better from under the engine instead of the top.It goes away after about 5 to 10 minutes when the engine gets warm.I dont think it would be a rod or anything I only got 92000 on the engine.I have not got a metal rod to find out exactly where it comes from yet.My dad says it just a normal engine noise that most of them do that.What do yall think.Anyone out there have the same noise its not loud its kinda quite infact but you can hear it.
