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

Thanks guys, I'll try to readjust them one more time. I actually found crane cams documentation and they said that if it's used lifter then you should let it decompress for a while (1-2mins) after loosening the adjustment. I just loosened the adjustment until I had some slack between the rocker arm and pushrod and instantly tightened it to a point of no lash + 1 turn. However if the noise doesn't at least get a little better I'll purchase new lifters just to be sure. I've had this car for a year and it didn't sound this bad ever before my adjustment, so at least something is different/wrong.

However I'm starting to think that it might just be bad lifter(s) and them getting worse after trying to adjust them. That's because I'm 100% sure that the lifter noise got gradually worse over the last month before I opened it up.
