Does Stihl MS660 oil the chain tensioner?

Does a Stihl MS660 pump some bar oil to the chain tensioner?  May clone saw looks like it does, but I'm not sure.  I would like to attach a JPG, but, so far, I haven't figured out how.

No, that is a valve is to let air into the oil tank. (It is just a ball and spring).

Your oiler is the horizontal slot above squared off area you have marked. Some oil will dribble down to the tensioner.

The tensioner isn't moving much, so doesn't need a direct lube supply. But like Charles says,. there is no real seal between the oil supply to the bar, and the tensioner. Some oil will tend to seep through to the tensioner, enough to keep it oily and stop it from seizing up.
