Used lifters should only be used on the very same cam, in the very same block, and in the very same positions they were removed from. Chances that the lifter bores will be machined on the very same angles on a different block as the block the lifters came out of are about equal to you hitting the lottery. If you purchase a used flat tappet cam from a swap meet or yard sale, plan on using it for a doorstop. New lifters should not be used on an old cam, either. Given the reasonable cost of a new cam and lifter set (~$100 ca. 2012), vs. the cost of cleaning and repairing the damage done by a failed cam and lifters, the choice to use new parts is obvious. | Used lifters should only be used on the very same cam, in the very same block, and in the very same positions they were removed from.

Instead, follow the manufacturer's instructions. If those are not available for some unknown reason (all should be found online), use motor oil or a roller lifter-specific lube for the roller lifters and cam. |
