what is it when it makes a ticking noice when you excellirate?

Dear thenamd-- Could be a lot of things.  Your problem might be as simple as some bad gas or it might indicate something more serious.  Aren't you still under warranty?  I would take it to your dealer to have it checked out.  Getting the final answer online from me would be like going online to ask if your cough is just a sign of a cold or are you really going to die next week.  Have it checked out. Don't let a litle problem become a big problem.  Good luck from Bovan.
