deceleration noise.

Do you have much experience with this engine? This is a fairly involved task to walk through over the internet. If you don't have the necessary tools and knowledge, you should take it to someone with does.

EDIT: Just saw the photo...That roller is only just starting to go. What does the cam look like? If the cam is severely damaged it could be the source of your noise, but judging by the roller I'd guess it is not yet bad enough to make much sound.
