Sealing Rim Joists for water

Hello -
Remodeling a basement and have noticed some water coming in from the still plate. I have begun to fix this with spray foam and will seal with silicone as well as make sure the outside is correctly sealed.

There is one other place that I have noticed water damage on the rim joists. along with making sure all outside joints are sealed I want to seal from the inside. Using silicone is had due to the space constrains.

Was thinking on using the roofing cement/tar that I could use a brush to reach in the corners.

Is this something that work or should I seal with silicone and insulation?

I donno,... I think I'd stop the water from the Outside, 'n let it dry out to the inside....
A run of flashing, whatever it takes to keep the water Out...

As Bondo said, divert the outside water with metal first, then inside- use foam board and canned foam to keep the basement air from condensing on it;
