Is this possible. I saw a post awhile back like last year where all the guy did to bleed the lifter was push down on the back of the rocker arm since they were already installed in a running sr20det. He did add a lil oil while pushing down on them. Will this actually work or will i have to completely tear down the timing chain and remove the cams to bleed the lifters?

i just read the fsm. So no i can't do that but i know i can check them by pushing them up and down while installed via pushing on the rocker arm. Tolerance is 1mm if it moves that much they need to be bled per the FSM.

UPDATE! pushed down on each rocker arm. No movement. So i turned her back on and all the noises went away. She's running great and very quiet. what a surprise.

Yeah bleeding the hydo's can be difficult. I was going to ask you ho your oil pressure was. Usually wuth goos oil pressure the lifters will essentially bleed themselves. The only time i would suggest bleeding them is after a complete tear down and rebuild. Like when doing the head gasket, or when changing springs, and getting head work.

When bleeding all you have to do is remove the cams, and rockers. Then cut a pop can half, fill it with oil and take a small allen key and "pump" the top of the lifter while making sure the lifter stays in a upright position. Then when installing just make sure to keep them as upright as possible.

Hey, when bleeding the lifters and installing them back in do I need a special tool to install them back in again?
