Getting ready to tear into both valve covers as they are both quite wet and appear to be the issue of a slow new leak on ground.

Did some preliminary research already.
Any techs that has performed this service give me heads up as to having access to rear cover (firewall) other than being tough to get to?

List
- Power steering puller from O'Reilly's.
- Felpro gasket with cam seal.
- Possible replacement of pulley, hopefully not tensioner either.

Ya that's just the front cover procedure.
I guess I should have dropped the cradle some. Even though I can't, I could've prepared to get setup at someone's else's house rather than at a very rich neighborhood...

Have inspection tools and mirrors to make sure it seated and hopefully it did, but did manage to tear rear cover new gasket on timing chain.

Can you loosen the engine mount and rock the engine to one side to give you more clearance?
