Unidentified Ticking Noise

[revised]

My 2005 Mustang GT Premium is making a ticking noise.

The audio file was taken on May 22nd. It is now July 4th, and it’s a lot louder and more constant.

I have had people say it’s a lifters tick, but I’ve also had other people tell me it’s a timing chain issue/timing chain tensioner/timing chain guide.

Please help me.

Check for exhaust leaks. Could be a gasket, cracked header..
