Not looking for any answers with this thread, but I broke the line from vac pump to brake booster yesterday, and have been fighting that for 2 days with no luck.
While car was running during vacuum checking, I had to run a dog off from across the street. Was walking back down the driveway, and I am still just amazed sometimes by the amount of smoke this wagon will billow!
No whining this time, just some pics to make everyone with a non-smoking MB feel better....

Jimmy, don't feel too bad I still have my letter from the SoCal Air Quality department when my vacuum pump had a hole in it and it was consuming mass quantities of engine oil through the intake. I was a magician for a few weeks....my crowning achievement was when I made a 95 Camry dissappear in my rearview mirror in a cloud of smoke

Looks like Andy's 300SD, before he replaced the bad turbo and got his fourth injection pump = a good used injection pump.

I think Andy still has him beat. Andy smoked out at least an acre at idle.

I think though that my smoke appeared to be more because it was dark grey.

I have that every day when getting started to leave. thought this was normal?
My neighbors are closing their windows when I roll up the garage ....
