"kockkock" Ewww pervert haha

Sounds to me like its coming from the chain guide. You should remove it by taking off the valve cover and taking off iirc, 2 screws that hold it down. Its between each cam sprocket.

Hmm..yeah try taking out the chain guide. its a good idea anyway to remove it ive heard horror stories of them breaking and blowing your motor. will only take you about 10min then try again.. if that doesn't fix it..might be a rod
