My question is, what did CAM do to make this happen? Even before installing CAM it was set to Auto in the bios and was fine? Could they have been conflicting with each other?
CAM probably changed the pump rpm slightly, causing the rattling, and it might have cause it to rattle at other rpm's now too. The slurp noise might also indicate that it might have had some air in it, or that it just pulled some air in with the rpm change, in which case the noise might just go away over time,
I'd just change the pump rpm tho wherever it isn't an issue. Pumps can be finicky, and a lot of them have sweet spots where they're the quietest.
