Oil In Vacuum Reservoir

I found oil coming out of my vacuum reservoir today, I looked around the internet and found that a failing vacuum pump will cause that. Can I just replace the gasket or should I replace the whole pump and solenoid? How much oil is too much in the lines? Are there any other fail points in the system I should check before I do the work? Thank You!

Your vaccum pump is bad
You can easily replace it three bolts in the back.
After you replace pump clean out your vacum lines and reservoir.
Make sure you order gasket when you order pump.
