Default Impreza 95 EJ20 SOHC 16v noisy lifters

Hi, i have a problem with noisy hydraulic lifters.

its only 2 lifters right side of the engine, upper and front (furthest from the oil passage). Ive tried 3 different oils and no change. I can get those working silent when take rocker off and bleed Air off lifters and put back in. It runs about 3 minutes fine and silent, then those same lifters starting to knockK. Done this couple Times. Problem with oil pressure? Dont think so, then all lifters knock? Oil pressure light goes off very fast when starts. Maybe worn rocker/axle or oil passage blocked oil pressure cant get to lifters? Tried olso engine flush and clean rocker with pressurised Air. Heard that maybe can change newer rockers with solid screw adjust from year 97 to x?

If any tips i would be glad

I forgot to tell that i have changed those twice. First Time it didnt help and it was still noisy after couple minutes and i bought more (was so cheap, maybe why its noisy? Brand is Ajusa) and tried again but same result

Given the wide range of prices in the second link I posted previously, which includes the Ajusa items, it may pay to bite the bullet and purchase some OEM ones.

The lifters need to be primed with oil / air bled from them BEFORE fitting otherwise they will never go quiet on the early SOHC engines.
Will PM you with the procedure when I find it

I did that Just like in video and merlins guide.
to all 8 lash and 3 times (when tried different oils) only those two not working.
My friend has 97 ej20 sohc with screw adjust rockers, i change that type if it possible.
I heard it should go Bolt on(?)
