Re: [MBZ] vacuum hoses, purge and water...

I have some minor leaks on the 300D -- worst one was a leaking oil 
filler cap, replaced them on all the Benzes and reduced the oil 
consumption considerably.  I never have to add oil between changes 
(6000 miles or so) on the 300D, have to add a quart or two on the TE.  
The 220D, when running, uses at least a couple quarts to a tank of 
fuel, so I ignore leaks on that one!

Check the oil filler cap for leaks -- remove cap, wipe area completely 
dry, and re-install cap.  The presence of ANY oil around the cap after 
driving indicates it's leaking, replace.
