Ive always heard its from pressure build up in the tank after running it. It heats up oil and causes pressure. Open cap to relieve pressure, put cap back on. I've never tried it though. Post if this works. I'll try it next time I use my saw if I remember. LOL
That's exactly what it is. There is nothing to prevent a leak in most cases, so if you can eliminate pressure buildup by cracking the cap open, that can only help. I suppose the cap should be left loose to deal with long term temperature changes, but probably the better solution is to burp it every couple weeks if you think about it.
