Abstract

The valve train assembly with magnet uses the magnet to collect ferrous metal particles that are in the oil prior to their arrival at the high pressure cavity of the hydraulic lash adjuster. The magnet can be positioned in the low pressure cavity of the hydraulic lash adjuster, in the bore of the hollow rocker arm shaft or in the bore of the hollow push rod.
