Default bad lifter?

93 lt1 had valve cover off and noticed one lifter pumping 2x-3x more oil than all the others is this anything to be concerned about? Lifters are about 2yr old ls type.

Is the lifter noisy? If not, I would just leave it. Your seeing the oil flow at idle I would assume. The oil will flow better to all when the engine starts to move up the RPM range.

Yes it's a little noisy but not at idle, it's makes noise from about 1000-1200rpm then it goes away.
