Can anyone tell me what purpose these actually serve?

They are simply crush washers to stop oil weeping up the bolt and leaking over the camcover Paul.

Thanks Ken

Nurse Julie:
They are a wafer thin that have been zink plated so, don't look copper. The later 550's had flange bolts  ;)

Bryanj:
Never noticed copper colouring on any of those, perhaps the zinc plating had not worn off as most of the ones i did were 1st time strip.
