Oh boy, what is this?

Well a new sound in my engine. Pretty sure it's the #4 intake rocker or valve. I was sure I'd heard every noise a 2XR/E engine could make, but lo and behold a new sound. Always interesting to learn something new. Gotta replace the clutch so maybe I'll pull the engine and poke around a bit in there as well.

In my 3 22s, sounds can be very deceiving.

This is one of THE best $20 I ever spent for my garage.

Any diagnosis? 

Gnarls.
