This a pic i found of Don's motor just through a google search of 218s. it had a clear view of this hole, so i decided to you useit. hop ya don't mind Don! i noticed that my motor has this hole in it. seeing as though the car was put together with JB weld, bubble gum and spit, i wasn't sure that this hole wasn't supposed to be plugged somehow.
i have no idea what it is for. anyone have any info for me?
