greddy oil sandwich plug

I just bought an ls/vtec from member on here, he says that there is a greddy oil sandwich on the back of it that has the one line for the vtec oil feed and that it has another hole for the turbo oil line, its a -4an. I need to plug this for now until i get the rest of my turbo build together, im gonna be running na until i can get everything. does any one know where i can get a plug for this and what do i ask for, do i just ask for a plug for a -4an hole or are there other dimesions i need to ask for? i dont want to be a total retard when i go to get it. THanks in advance

huh. jsut goto any autoparts store and ask for a 4an plug. jsut rememerb to ask for the proper end. femal or male.

male would be what i need right? there is a hole tht needs to be plugged in the adapter so the plug it self would be male? i may just take it off before i put the engine in and take it in and find a plug that works
