Engine passage question
Hi all. I'm attempting to refurb a CL A4 purchase. One task is removing a good amount of rust debris in the block. Per a4 manual, ive been able to excavate and open passages via coat hanger/welding rods. One passage has me puzzled, however. Its in the flywheel end, starboard side of the motor under the starter. might anyone know where this passage should lead? Seems lower than the cylinder cooland area, but doesn't seem oil related either. Pic attached. Thanks much for any assist.
