Oil control Orifice.....can u run w/o one? what is it

hello well
like i said can ur car run w/o one? (oil control orifice)
reason why i ask is when i had head/block assembeled i forgot to put the dowel/guide pins in.

and i got thinking if i forgot to put them in maybe i forgot to put the orifice in.

the car is going in the shop tuesday and i just wanted to know b4 hand so i can buy the part hopefully b4 it goes in

but obvisouly if the car wouldnt run w/o it then its in :slight_smile:

lmk
thanks

you NEED that in there. my friend got by for 2 months without it and then the whole engine blew cause he left it out.
