The stage v rockers and adjusters I recently purchased from FHO have oil thru adjusters. manton PN 824-01  In addition you need to make certain that the Lube hole in the rocker is above the top of the PR cup So why would you need oil thru adjuster's, if its shooting oil from the hole in the rocker onto the top of the pushrod? Added oil to the ball/cup interface. My seat pressure is 340 lbs and 650lbs open. Without the oil hole on the adjuster, Tuneup time and 10 passes blackened two cups and wore half of the adjusters. Replaced the adjusters only with the through hole and over 50 passes no issues starting the season with the same parts as last season.
