its in 06.. about 100 hours plus.. he took it to pro cirucit about 2 weeks ago for a valve adjustment(or check).. been doing it ever since. its the original chain to so.. to me it sounds like its comming from the valve cover.. i told him to replace the thing anyway due to the amt of hours on it..

Wise to replace it periodically, but it would be interesting to see if PC opened up his clearances some and caused all the racket that way.
