Hey all I just started to notice this loud ticking noise coming from the top middle of my engine bay above engine block. I should have known something might go wrong when i had to go back to the dealer after my oil change becuase my air pressure sensors were showing that one of my tires had 25 PSI and the other 3 were at 34. Yes I checked that they put oil in the car. I always check everything out after I have any one else touch my car besides me. My engine has always been very quiet until now. I am not just being sensitive to the usual workings of the car. Something is causing this noise and I want to know what it is! Please listen to attached audio for more details. I have found a couple of other chevy owners who have posted similar sounds on youtube but there was no comments on their videos! if you have any ideas on wha this is let me know asap! I am bringing the car to the dealer in a couple days and would like to have some of my own ideas as to what the noise is to discuss with them so I dont get the usual bs back.
Thanks! AUDIO HERE!!! http://www.youtube.com/watch?v=tjMQ1yXaJ7o
