Third request for "show me your nipples" please

I have the popping sound if I open the oil fill cap. I have vacuum tested both of the mounts, all the pipe work from the vacuum pump to the mounts and the pump itself (engine off) so I'm wondering if the leak is on something else the vacuum pump feeds?
does the vacuum system run anything other than the mounts and brake system? (mine is 2014 so the turbo system is not affected by vacuum)
