Vacuum Tank

G'day Men, I've come across an issue that has me stumped and thought someone might have an answer for me. Yesterday while fitting new vac hoses, the hose pipe on the vac tank came loose. After removing the tank, and a right pain in the rear end that job is, I started cleaning everything prior to resoldering and was surprised to find a large quantity of oil in the tank, maybe up to an inch or so on the bottom. Now my question is, where in the bloody hell would that oil come from? Is that something purposely put in the tank for some specific reason that I can't think of? Regards, John
