Oil Flow Through Single Vanos on 1997 Z3 M52 Engine
I don't have an air test fixture for testing flow through the Single Vanos on my 1997 Z3
M52 engine, so I thought I would see if some of the Vanos Gurus on this site might know the answer.
Question: When the Vanos solenoid is energized and in the outward position pushing the solenoid piston and spring inward, does the oil being diverted push the actual/main Vanos Cam piston in or out? Also, when the Vanos piston is pushed outward on the camshaft, is it advancing cam timing, or retarding it?
Thanks in advance
