This gentleman's question is EXACTLY the reason I felt the need to address this subject seriously, ONE MORE TIME, especially if you've got one of the 'THREE PORT' Canadian blocks, or you're running an oil filter.
The "Grub Screw" is a plug which, in this case, CAN be threaded into (or DELETED from) the horizontal oil passage between the inboard port and the outboard vertical port on a 3-port Canadian block. The grub screw can be seen with an arrow pointing toward it in the shaded portion of this drawing. You should read portions of this thread again thoroughly, or read some of the threads in this link below for a broader explanation. Come back for more if you still have questions.
