Check valve in the oil filter housing

[Santino]

Hi guys
lately ive observed that the red oil pressure light was on for a longer time than usual, after engine start
and how it turns out oil filter housing after some time is going empty.
any ideas where is the check valve that keeps the oil in the housing when the engine is not running?

Got a video of how long is longer?

You need to remove the oil filter housing from the block to have access to it, it’s in the oul filter housing.

ok thankfully its not so hard to take it out as i have
