Original post of 'bag test'.....
The original thread was
Drive car for over half a day, it shuts off!?!
My '87 300D W124 test is shown in that thread as posts 10 and 11. With the '87, the bag filled in 3 minutes, but not tightly -- see the photos in that post. I'll test the '85 this evening and post results for it.
As regards air being sucked into the engine and then blown out, thus increasing apparent blow-by, the vacuum pump vents into the crankcase, doesn't it? Perhaps that is what 1983/300CD meant when he suggested unplugging a vacuum line. Are there other places where air could get into the engine?
