Stihl ms 250 OIL TANK VENT?

[KYXR600]

I have a stihl ms 250 that oils out the wrong side of the bar. It leaks out of what appears to be an oil tank vent located near the muffler. We have another stihl ms 250 but it has a little orange vent or plug of some sort whereas on this saw there is nothing, and on stihl's schematic its not shown. Dont tell me a new crankcase housing is the only way to get this vent.

it is just a blanking plug get a nylon rod that will tap in the hole just do not go to deep as you will stop the oil flow there is no replacement plug from stihl but they do a grub screw to thread in there

hope this helps
