Q: New Hydrolyic Valve Lifters making noises, Want to clean/clear up its oil pipes! on 1990 Mercedes-Benz 190E

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Old hydrolyic valve lifters making moises, so I have them replaced with new lifters, but still making noises.
So I have the new ones checked if there is oil in the lifters. There is no significant oil in them. I believe the lifters' oil supplies pipes and so on, need to be clean/cleared up for oil to flow better. I'd appreciate any recommendations for solvent or liquid solution used and methods!. Note the oil pump is working fine, with enough oil pressure.

Thank you.
