that is one of the head oil return ports that tend to leak if you dont have that 10mm tight but it wont hurt the idle though. something else is wrong. does it sound like your missing a cylinder kind of idle? when you start it do you have a lifter noise clackle? I have had this happen I just pulled the cams and re did everything again to make sure rockers are seated correctly shims are in place torque is to spec. OH and did you tighten down the cams starting middle outside to inside hand tight then repeating till ready for the torque wrench?
