Looking for root cause of oil leak

Update:

Definitely the rocker box gasket. Pressurized the motor per J Sachs' procedure and it bubbled right where the red arrow on the right is pointing. Slick process and accurately diagnosed. Thanks guys.

Since I'll be replacing them, is there a concise procedure on this site that I can use to guide me? I found one from '08, but no pics.

This is from the 08 manual. Page 8-2 has torque specs, Page 8-3 has parts breakdown , 8-11 has the removal procedure and 8-15 starts the installation procedure. Hopefully this info is what you needed.

If you have NEVER replaced lower rocker box gaskets, you need to be EXTREMELY careful re-installing the push rods , and rocker assemblies, etc. You can do a major amount of damage to the valve train parts, $$$$.

Job complete. Clearly, this is the reason for the leak. Thank you all for the support.

Glad you were able to complete the job. I received good advice a long time ago to help avoid gasket leaks and it was simply to let your engine warm up a long time (ride easy 15-20 minutes) before getting on it hard.
