I've just gone through this with my car. It's the MC pushrod hitting the edge of the endcap (washer under the circlip). It made an awful noise.

To prove this, I made an offset clevis and the noise was gone. See pic below.

It only cures the noise. The sideload will remain the same.

The rule of thumb is no more than a 5 degree offset for a cylinder pushrod, yet Tilton claims a 3 degree max. No doubt their endcap hole is only large enough to handle 3 degrees. So I could drill it out a tiny bit larger. My angle is 3.7 degrees.

Before doing that, I went with the offset clevis. I don't want to leave it that way as there is now a bending moment on the pushrod, so I'll no doubt drill the endcap. Moving the clutch bellcrank hole closer to the pedal pivot would lengthen the pedal stroke, and I don't want to do that.
