I found a yellow-orange, odorless, thick oily residue in the vac line coming from my cruise control servo. I was pulling vac lines checking for cracks/holes/leaks etc, pulled the line from the servo, blew thru it to check if it was clear, and this weird residue came out. The same residue was all the way back up the line at the check valve on one end of a t-connector, located against the firewall and right above the vapor canister. Any ideas about what this could be?

 

just oil with condensation in it.
it's nothing to worry about. just clean it out with carb clean.

 

Thank you...I haven't seen this in any other vacuum lines than the one on the cruise servo, so I was concerned about it having actually come from the innards of the servo itself.
