Timing chain tensioner

after reading about all the issues ive been thinking about doing a manual tensioner on mine being it has 1700 miles on it and not sure if its ever been touched
just trying to see if i can find a write up or install video of how much is involved. I have a good set of tools and good mechanical background so trying to see if this is something i can tackle myself or if i should just take it to a shop type of deal

mine is a 2013 570
