rocker or lifter noise please help

I haven`t had a lot of luck with hydraulic lifters either. The sets I bought for my big block and small block both had one lifter that wouldn`t pump up. I eventually went solid on the bb and since the sb is staying stock, I`m just going to replace the one lifter that`s not up to pressure. One alternative would be to buy the anti-pump up lifters offered by Crane.
