Can a lifter become unstuck?

Will thicker oil stop lifter noise?
Heavier oil will not quiet hydraulic lifter noise. The noise will usually go away as the motor and oil heat up. If the tapping continues after the vehicle is warm, you may have one, or more, faulty lifters. As any oil gets dirtier, the chance of lifter noise increases; heavier oil just makes the problem worse. via
