I just took one of mine apart today. I think I know what it was that fell out last time............it was all the little "scrapers." this time, I was very carefull to take it apart and examine.
I am still not sure how exactly the motion is controlled. it seems more like it would be either fully advanced or not.
What controls the amount of motion on the phasers?
Is it the oil pressure that rises as rpms rise, or is it just the pulsing of the oil contorl solenoid. Either way, I'm not picking up on it yet........I think I need to stare at it longer!!!
