Most obvious is low (insufficient) oil pressure at idle. Seems to be supported by the loud tapping mentioned in your other post.
Could be an issue with the oil bypass valve. I think on these engines it is located in the oil filter canister. Perhaps another poster can confirm this.
Could be an issue with the oil pressure sensor.
Could be a worn oil pump.
Could be a clogged screen on the oil pump pickup tube-screen.
First think I would try is to buy a new oil filter canister with new bypass valve.
Easiest cheapest simplest.
If that doesn't correct the problem then go to the next easiest possibility to correct.
Work your way up the difficulty ladder.
