Question Re: Air leak sources questions

1. How can this be when it is connected/inline to the same pipe as the air cleaner?

2. Does this blown head cover show signs of running lean from an air leak?
That might assist in keeping the cap from loosening , and that would be a something to consider . As for sealing it because it is letting air in even when it is secure , that sounds like overkill . That head shows signs to me of being rich . Is the head itself ruined for some reason or just the gasket ?
