Knock? video included
Hey guys, can you have a listen at this video and tell me what you think? It actually sounds worse on the video, but hopefully that will help diagnose whats wrong? http://www.youtube.com/watch?v=SYiEfsBLLLE
I'm guessing but, does it seem more at the timing chain end of the head?
Maybe a timing chain tensioner to make a guess, hoping it isn't in the valves.
Can you isolate the sound with a shortened wooden broomstick or something used like a stethoscope to the ear/skull bone when touching various places on the valve cover or other potential sources?
The vibes/scraping might be identified louder as to specific location using something like that.
All your fluids up ie, p/s reservior.?
Noticed anything "funny" with the exchange rates and parts prices lately:

sounds like a great place to start! check you fluids and then its time to remove your valve cover and check it out since the timeing tensioner is a usual thing. i agree i hope its not your valves cuz i sounds like its on the outlet side. i dont know but i have asked this befor but what are the valve gaps needed? because it is a good thing to check and re set every once and a while too!!!! good luck man

sounds like it might just be excessive valve lash
