The oiling setup shown in the link was together for 4 seasons with a decent amount of street miles and probably 100 or so passes. I had 2 rollers that were ready to be replaced when I tore it down. That's with just over 0.800" lift and about 760lbs open pressure. This time around I have the block bushed and I raised the oiling ports up in the lifter bores a bit. I think I had them breaking through too close to the bottom of the lifter bores so a lot of the oil bled out the bottom. I went with a bushed lifter this time around too.
