HLS,

I do thank you for the response. It always helps to have someone to talk to
on these
issues. But Here's what I found, for the record.

Therace-way, for want of a better term, is in two parts. The channel  clips
onto
the valve cover, and the lid ia separate. The lid clips to the channel.
However, you can remove the entire assembly as one piece, and that is the
better option.

To remove the assembly, slip a flat blade screwdriver under each of two flat
clips, about 1/2"
wide on the LOWER edge of the sssembly, completely out of view. There is one
aligned with
each of the half-moon tabs visible from the top and covering the valve cover
bolts. Once these
clips are released the channel, and the attached lid, can be slid UP and
free of the valve cover.
Once that is off the lid can be released from the channel with a bit of
prying. There some clips at your
right (left side of car).
