What kind of oil pressure do you have? It is fairly easy to make a tool to take the original ones apart and clean them out.

5 bar at 4000 rpm , i have replaced we new one but i have not pre loaded new lifter with oil on bench prior to install

You should not need to soak them be for install. It's pretty much impossible for oil to get in them without pressure. The should stop ticking after a minute or so.

So what can be trouble why not gey pressure on camsgaft bearing?
System has 5 bar pressure at this point i m not sure camshaft bear has so much oil prex
