You can not build boost just reving the engine in park.
So it can’t be boost coming out the valve cover.
Could be a head gasket,but cars with a bad head gasket usually idle and just off idle,run poorly.
Pistons going up can pull air in and pistons going down can push that same air out.
Proper system keeps crankcase under vacuum, assuming rings and valve guides are good, so cover your valve cover with your hand and see if your PCV valve is working at idle.you will need to come off idle just a little for it to start sucking.

What's your BLM's at idle with the engine warmed up?

Scoobum,
If I remember correctly, blm = 132, warmed up at idle in park.
