timing cover leaking help

i have a 2007 tacoma and im the second owner, with 110,000, wanted to know if the procedure is easy to fix, im just getting into working on trucks, my dad has been working on tacomas for 30+ years, also my truck is supercharged and i wanted to know if the procedure was different, any info will help me, also what tools i will need to finish this job, my leak is pretty severe it runs down all the way to my oil pan from valve cover on the passenger side

 

I've heard that the procedure isnt very easy. I have a 2006 4.0 V6 and it was still under warranty when I took mine to the dealership and they had it for about a week cause I guess they had to raise the entire engine.

 

thanks for the info
