Oil cap leak 025... New cap or 23x3 o-ring?

[schmauster]

Should I get Buna O rings that fit the screw in caps for the 025, new OEM flat rubber washers or a new cap? My oil cap is leaking.

Prepping the saws for another year of wood cutting... Last year i was happy they were running well (crank seals) This year (moving forward luckily) id like them to not leak a bunch of oil when sitting upright.

Basically.. If the O rings work well i'd love to have a ten pack of them ready... If they dont work as well as the OEM sealing then ill go with that

O-rings are cheap; try that first.

Could be that the cap is cracked or beat up one way or the other. That means the rubber rings won't work float or O. Considering the age of your 025, I would consider finding new caps. I made a cap twister in my shop rather than use a screwdriver to ruin vintage Stihl caps:
