'81 240 D, green vacuum line question

Used Mercedessource repair manuals and vacuum pump to find vacuum loss on green line going into firewall. Comment in manual suggests this is vacuum line to Climate Control. Not sure this car ('81 240D) has climate control.

Pulled instrument cluster and could see vac line going into upper center of dash. What does it connect to and where would I find it? I hate to start pulling the dash only to find it was a simple repair if I had just known where to look...

Thanks!

300D Leaking Valve Cover Gasket

I have completed a valve adjustment and replaced the valve cover gasket. After running the car, oil can be seem around the edge of the gasket where it meets the engine block. The bolts are tight and I donot understand why there is a leak. The gasket was obtained from a OEM operation. Should I get a gasket from the dealer? Have other people experience this problem?
