Thanks for replies guys,
Seems to be almost gone after timing belt,waterpump and pulley changes. But yeh I ran it with top cover off after, and not really any noise, soon as I put standard timing cover on it was noticeable, and I took it off again to notice I couple blue marks Inside the cover from the belt... spent hours trying to put it on and pull it to one side, or up, even down before bolting it up tight, but no luck, still had a slight noise, nothing like those original videos though.
I just put a clear timing cover on because they seem to have alot more clearance around the belt. Maybe my old one warped slightly, who knows.
I did the belt too tight the first time and geeze, it definitely tells you in its own way it doesn't like it...
Seems to be fixed. I wish i knew some RB geeks in Adelaide
