VX Valve timing oil pressure unit

Been awhile since I am on here.. but it feels good to be back on here.
Long story short, dad got my uncle's 92 VX and I am in the mist of tuning her up before smog check.
So when the car turned over, I see oil bubbles around the Valve timing oil pressure unit. It should be the gasket needs replacement, but what information I need to worry about or just unbolt the (2) screw and replace it?
Any info helps and thank you.
