I thought id start a new thread because my other one is rather long winded .
Anyways, I have been examining and researching how the Vanos works on these Engines and found a few things odd on mine... I have never really worked on internals like this before, so bare with me.
A) When i rotate the crank by hand, the cams do not move in uniform. They seem to almost stop for about a 10* period of the crank rotation, then they continue.... they seem to do this multiple times during a single rotation of the crank.....
B) The Camshaft reference wheel mounted behind the sprocket... is there a fixed measure that the notch on this should be from the chain tensioner post at TDC? Mine seems WAY further then any pictures or videos i can find... at TDC its nearly 48MM from the post... others seem to be in the 35mm ballpark.
C) Vanos.... is there any way the piston or ports in the vanos control system can get plugged in a way that the vanos would always engage when the engine runs?
