You will need to find the "where". No one on the brickboard can where your leak is from your description,

Both Dick Reiss (Dick often posts here as "dick") have had trouble with our cars (he has a 1991 940SE, which is a combination of a 1988+ 760T and a 940) with the sealing at the vacuuum check valves on top of the engine.

Below is a picture taken of the engine on our 1988 760T. It shows the vacuum check valves and the worm drive clamps which cured the vacuum leak(s).


Your problem could be there, or it could be inside the car. Try the small worm drive clamps, and then check the vacuum servos inside the car. There is lots of good information in the 700/900 FAQ. Check the FAQ for sure. Vacuum leaks can be difficult to find, but they can be found if you are willing to work hard instead of paying the repair shop.
