I mean its not so much of a loud sound... its just noticeable when i park sometimes and walk out with the engine on. When i am driving i don't really hear it whether i have music up or down.... when i visit my dealer in 2 weeks I will have them check that out, also I know i do need an oil change. Lets see what happens..
... but i doubt that would do anything..
I would def get yours checked out right away. Mine was built 4/06 and the problem was already addressed by the time it was built (according to the service dept), but you may have the bad lifters with your earlier build. Mine ticks only in the morning when cold, they say that is normal.
