Typically this happens when the VCV is filled with oil, sucked
from the IP around its seal. Stops leaking and starts acting like a shock absorber. <>
The switchover valve only controls the EGR setup, and has NOTHING to do
with the transmssion on 722.11? cars, approx 1978-1980 normally aspirated
616 and 617s. It can be confused with bowden cables because they share a bracket on later models.

Thanks for all the info. Two questions:
1. Is there any way to clean out the VCV? I did notice oil sitting inside the top vacuum line connection. I was hoping it was residue from my recent oil change. Perhaps not.
2. When you refer to the switchover valve, that is a new term to me. You don't mean the white, 3-port vacuum switch on top of the valve cover, do you? If so I don't understand what you are saying... on my '80, the vacuum supply from the main line runs to that, with an offshoot line then supplying vaccum to the VCV....
Cheers
