Mate, I get the feeling you have not maintained the crank at TDC while you did this work, I have had a quick look at the manual PDF I sent you the link for, and if the silver links are not aligned with the circle marks when you started (hence your yellow marks) then I would suggest you download the manual, remove the harmonic balancer and front cover and start again fresh. You have been struggling with fix since early November, you probably need to get someone knowledgeable in front of this engine to help you.
