Post hydraulic roller lifters

Installed a compcams retro roller cam & lifters in a sbc. Ran a short time & tore engine down. Bored,more compression. Problem is lifters, stored well protected,washed & blowed dried. Upon installing cannot set pre-load. Lifter acts like it is pumped up or a solid witch they are not.Soaked overnight in slovent and dried again.
Still cannot get plunger(?) to move off seat to get proper pre-load. Any ideas or sugestions will be appreciated. One last note I really don't want to throw these away! I am not that familiar with this type of lifter problem. Thanks

Leave them upside down for a couple of days, then using an old pushrod and a piece of wood give them a rap with a soft face hammer while they are upside down. I put the old pushrod in a vise. Be very careful you don't damage the roller bearings, a little rap is all it should need once the oil has drained out. What has happend is the oil has thickened to the point of being as thick as STP, sometimes a little oven time at 200 degrees Farenheit helps too. Send the wife shopping while you do this.
