Hydr lifters, adjustable roller rocker arms, had some noise, tried to adjust preload did i mess up?

I've been following this thread, very good info...as always from y'all,. I've read that stock cams are designed so that they reduce lifter noise as much as possible. Performance cams designers couldn't care less so those cams are naturally noisier.

My question for the op - is it overall noise you're hearing or an actual lifter tick from maybe a bad lifter or out of adjusted rocker?
