1995 E36 M3, strange noise.



There is a strange noise appearing to come from the Vanos area under 
deceleration and below 3000rpm. It sounds similar to the wheel of fortune and 
is more plastic than metallic. We have pulled the valve cover and inspected 
the timing chains and tensioners. These all appear to be okay, and show no 
signs of wear. Can anybody tell us what is inside the Vanos, other than the 
plunger gear, which could make this sound?
