Just spoke with the shop and the diagnosis is mixed. The "golden thimble" is a protective cap for the rack. The shop is going to disassemble to verify that no damage has occurred. There has been an observation that the govener is tight. I don't know what the exact function of the governer is, but please chime in if you know!

I should get it back with injectors tested by middle of next week.

What does the governer in the IP do?
