I did my cam chain and adjuster last year easy job just takes time 
Cams don't need to come out 
Time it up to TDC 
Take off the Engine cover and intake pipe off 
Rocker cover off and cam chain housing  
Lock up the cams with the locking tool I would suggest using genuine tools and especially for the cam adjuster bolt 
Undo the adjuster bolt 
Pull off the adjuster tensioner too chain off replace and reverse the order putting it back together get new gaskets for the rocker cover and cam chain housing too
