A lot of slack in that chain you pictured . Must be a chinese chain or improper fitment . How did you adjust the cam timing? 10 years and no wear on a teflon wear pad? Lifter Failure wiped the cam? and your happy with it?
No I am not happy that a roller on a lifter failed, but I bet you can't prove that the tensioner caused it either. I did not dispute anything you had said up to that post. I just posted my observation and experience.
