I had my valve cover off this weekend to adjust the valves. I decided to check the 'chain stretch' but am unsure of whether the pointer showing 5deg or 2deg. Also, I am unsure of what to do next, does the chain need to replaced (car has around 150k on it) or is this tolerable?
Here is a pic of the indicator on Flickr: http://farm5.static.flickr.com/4018/4702434216_986910dcca_b.jpg
