Check the oil pressure with a mechanical gauge-could be the oil pressure relief valve is stucked closed not opening

Pressure relief valve is a spring in oil pump, If mechanical pressure is verified, replace oil pump.

Should not be oil pressure problem. Engine is experiencing excessive blowby. Check the PCV and crankcase ventilation systm.

You could have an aging engine that has worn piston rings.
