Thread: Camshaft adjustments for performance improvement

  1. #61

    Re: Camshaft adjustments for performance improvement

    EPC documentation says that conical spring inside cam adjuster has changed several times. Spring diameter has grown from 2.1mm -> 3.0mm. Any idea what problems that older style and probably weaker spring can bring? Thanks

    Re: Camshaft adjustments for performance improvement

    The spring changes were made to minimize rattling noises, especially during start up. There is no change in the performance. And for those that may not know, the cam adjusters on the M119 are not continuously variable. The solenoid and it's dependent valve are either fully open or fully closed, and the camshaft is either fully advanced or fully retarded.
