CM2350 fuel rail issue

[ktblogistics]

the crankcase filter was like that,also there was slight film of oil on boost sensor when i replaced it
did fuel system leak test before and it mostly drops up to 5k within 1min , few times saw no drop at all, but it is the first time i see that it drops like that in the blink of an eye
also expected to have 300ml or more when i pressurize the rail to 30k psi an measure in jector fuel return amount,
checked the line if bended but not and have only 100ml in the cup after 1min
