Update: Took it to a shop, they adjusted the valves, didnt cost much, they said thet were out of adjustment. Started the car up, and I still hear a clicking, but I have narrowed it down to a zone. Near the fuel rain on the drivers side...

Can an injector make a fairly loud clicking noise? (somthing you can hear with the hood shut)? Maybe I have a bad injector?

Exhaust looks fine, no smoke or anything.....
