I have been hunting this leak for months, changed intake gaskets, changed the intake itself but nothing has fixed it. Leaks right at the #6 runner but can't pinpoint where. Anyone have any ideas on what could be the problem, maybe warped mating surface, crack in the runner on the head?

 

What engine? What year truck?

 

Opps, forgot the essential info haha. 2000 with the 4.7

 

That one, I just don't know much about.
