So it runs downward at an angle into the bar tension screw area correct?

Looking down the bar towards the trigger you will see between the muffler and the bar a small hole. You need to look close. Clean off the area with air and take a look. If there is an opening your missing a set screw that needs to go in there. (PHOTO Attached) Seen many that leak from there. You’ll need new set screw to go in there.

Oh and if you do see the orange plastic plug, this is not your leaking issue
if it’s missing you need to get a set screw from stihl. (Still looking up part #)

Oil leaks are my pet peeve, don't mind one that marks its spot after hard use, but it it dumps an entire tank just sitting on the ground is not tolerated!

Found that the vent was plugged with debris and the oil cap on the 029 super was the original one and was leaking a lot of it...
No more oil leak! So see you did find out it just took a while.
