Everyone is correct I just went and changed my timing chain and the dampner and the chain had very little play less than recommended but since I was in there I changed it. I just past 106 thousand now the dampner that supplies tensio to the timing chain was worn it had a timing chain grove in it about 5mm not a whole lot but like I said I was in there so I changed it along with many other things wish I had the money to change the cam but I was told I have to many toy's.
So if you ask me do you need to change it well is it a day to day driver or a racer? If it is a day to day driver leave it if it is a racer get another motor to play with when you get everything!!!! you want on it then swap it out.
