Dave Faria Posted May 27, 2010 Share Posted May 27, 2010 My reason for looking at this is to determine if closing rocker arm end float will increase oil pressure at the tensioner. I've not had the rocker assembly apart and all I know is the main oil flow enters at the top of the intake valve rocker and exits at the bottom of the intaker rocker. It then goes across the bottom bearing and then up the exhaust valve rocker and then exits at the top of the exhaust rocker arm. It then flows back down the chain channel to the oil sump. My Questions: Does closing rocker arm end clearances increase oil pressure at the tensioner or is oil pressure actually controlled my metering ports in the rocker arm shafts?? Does closing the cleances only decrease the noise by removing play on the shafts??? Link to comment
