Do you mean,,,After the valve is adjusted, I should or should not be able to push the rocker down this extra .140 travel? Its pretty easy to push down.
Do I need to remove all clearances (this .140) and then adjust the valve? Thanks.
After the lifter is adjusted you still will be able to push it down.

For whatever reason, that lifter is not filling or is not retaining the oil that it uis supposed to fill with when the engine is running.

If the lifter is plugged and is unable to fill with oil when the engine is running, the lifter will be noisy, performance will be off and the valvetrain (cam, lifter, p-rod, rocker arm) could be damaged.

Sometimes the lifter can be removed, taken apart and cleaned, then returned to the engine. You can't usually get away with replacing a lifter w/a new lifter on a cam that has already been used because the lifter and cam wear in together.
