Brian,

Thanks for your suggestions. I have looked through many posts, but am struggling to find information about what must be done to correct a jumped cog.

Strife,

My references were a booklet on avoiding catastrophic engine failure from **************.com, as well as numerous posts on this forum, and the DIY guide to changing the timing chain also on this site.

1) The spark plugs are out.
2) The RH cam followers are not removed. There were mixed reviews about whether or not this was necessary, so i left them in to save time.
3) I was unsure about the tensioner. I left it in, with plans to change it at the end.

Yes, i filed off the rivets from one chain link and pushed the pins back to remove a link in the chain and then used the new connector chain link with the c-clamps to attach the new chain to the old.

To be clear, do you think the binding of the engine is due to me not removing the cam followers rather than my assumption of the chain being off on the passenger cam cog?

Thanks very much to you both,
Justin
