It's not uncommon for a lifter to go bad or clog up keeping it from pumping up. You can either replace it or dismantle the bad one and clean it. If it don't clean up and restore the sprung preload, toss it and replace it. This is all assuming your running a hydraulic cam. I run VR1 10w-30 in both my 72 Chevy's, I have to buy it online because the parts stores seem to only stock the 20w-50 VR1...Good oil! Good luck...If you wind up replacing the lifter, give the bottom of it a smear of the dark Moly Lube grease before dropping it in the hole to help it mate up with the cam lobe.
