Thanks for your reply Laurence

The engine has even compression across. It has been over a year since tested but something like 175 psi. I was rather surprised and pleased.

I would like to avoid pulling the head at this point. Are there chain ramps/guide that are accessible once the valve cover is removed?

What is entailed to change the tensioner?
