Yep, it is a matter of volume. The little plastic tubes do not provide enough air volume, so the engine just sucks the fluid into the throttle bodies. The vacuum chambers are like shock absorbers, providing a cushion of air between the engine and the oil. With no "volume", just a total of 2 metres of pipe for each cylinder, this picture is with engine running. [IMG]https://atrophy.lock.net/pi/20080110/tmp/1_DSCF8408.JPG[/IMG] It only sucked up when I had a leak, and then it was slowly enough that I could take a picture (see previous post). Because I was concerned about sucking up, I did initially put clamps on all the pipes, then release them slowly. In the end, they were not needed. I say again, using engine oil gives a lot of damping. To the extent that adjustment has to be done slowly, allowing a few seconds after each movement of the adjustment screw. [/QUOTE]
