If the job is full customer pay, I believe the book labor time is close to 20 hours. There are a ton of little gaskets and o-rings, which add up quickly as well.
What you need to find out is the severity of the leak. If it's just a seep, then it does not need the re-seal yet, and should be monitored and checked at each service.
I really wish Toyota would've never switched from timing belts to chains; so many of these engines end up leaking. Don't get me started on the 5.7 cam towers!

Whether its belts or chains, they still have a timing cover. Have 350K miles on a 2014 and no leaks. So definitely prefer the timing chains.
