Does this sound like an exhaust leak?

Noticed a ticking noise today while the XJ was idling. Does it sound like an exhaust leak to you? As I moved the camera it sounded a little more pronounced around the middle cylinders.

 
That's where my original one cracked. This is an APN replacement that's been on for 3 years but only has about 1500 miles on it.
 
Sounds like either the gasket is slightly leaking, or its just normal injector noise. Doesn't sound like anything internal.
 
Get yourself a doctor's stethoscope (~$20) and replace the sensor head with a 12" length
of brass tubing. It's great for probing and pinpointing air or vacuum leaks whenever your
engine develops a hissy fit.
 
I'm fairly certain I have a leak. When I started it yesterday morning I could see exhaust coming up from the manifold. I'm going to go through and double check all the bolts to make sure they're tight.
