Oil leak/seep

Hi All,
I crawled under the car today to check the engine mounts and saw that there seems to be oil seeping or leaking out of the the exhaust headers(i think). It is just this one connection that has the problem.. the other ones seem fine. Do you guys think this is a big enough problem to warrant repair? (I have third party warranty, but the parts approval process can be a PITA is the problem is small).

Heres a pic of the problem


Thanks

As posted elsewhere, too, I'd be 99% certain this oil has dripped to this location from somewhere else.

If oil could leak through the gasket there, so could exhaust gasses and you could likely feel and hear that.

50% chance it's your cam expansion plug that's causing the leak
