Put a filter on shut off vacuum line
I recently discovered that despite the fact that the engine shuts down fine the shut off diaphragm was leaking oil. It has made me think we should put a clear filter in our brown shut off vacuum lines so that oil leaks into the vacuum system are visible. I had assumed that a diaphragm with a hole in it would manifest with poor/no shutdown so oil leaks would be readily detected. Apparently not so.
I haven't found an appropriate filter to go in the line but I will look for one when I next visit an auto parts store.

Or, you could put the couple dollars a filter would cost towards the cost of a new Vacuum Shutoff.
Does the Vacuum Shutoff hold Vacuum?

I'm going to replace the shut off valve. I'm talking about putting filters in that line as a general principle on these vehicles.
When I pulled a vacuum on the shut off valve, it just sucked oil.

I couldn't find clear small fuel filters at the auto parts store but found a clear 1/4" lawn mower gas filter at the hardware store. With a little dish soap in the hose, I was able to force on a piece of vacuum tubing to each end which will also fit the brown vacuum tubing in the car.
The W116 300SD had no OE vacuum filters that I can see, unless a PO removed them, but the lines look original. Since it has the dual diaphragm vacuum pump with separate lines to the brakes and everything else, a person would also need a filter in the large brake vacuum hose to detect a failure in the pump vacuum diaphragm even if a filter was put in the 'everything else' line.

I would not put one on the large brake vacuum hose as it would become a restrictor and reduce vacuum to the brake system - not a good thing

I knew there had been other threads on this topic but I added this one because I was not previously aware that a shut off valve could leak oil profusely while still functioning perfectly fine. Hence, the need for the filter.

I picked up those filters at a Good-Guys street rod show out in the swap meet.
In my first picture, the 3 way connector between the filter and the yellow check valve. It`s one from under the carpets for the door locks. I got rid of the spider connectors, this one makes it look real tiddy and clean. Charlie
