Just wanted to add a BTDT- when I did mine (1988 90) there was very little
oil in the vacuum pump, in fact so little that the whole time I was
cleaning it out I was convinced that I was probably wasting my time. For
some reason, I expected it to be practically awash in oil.

	Reinstalled the pump, no rap. Amazing.
