You may want to use butyl rubber caulk but be sure to have some paint thinner for clean-up. It is sticky and stringy.
Thanks for the welcome. Whatever the styrofoam is for it has helped my sill plate from rotting
. Thanks for the tip on the butyl rubber caulk...I'll take a look for it.

If it were me, I'd be looking for a major air leak, and not a water leak...unless I'm missing something here.
Oh, and I would use spray foam if possible.
Sorry I guess I wasn't totally clear. The water isn't coming in now during the winter. I determined the source of the leak by pouring a pail of water around the bottom of the patio door...that is the water I am talking about (and am assuming that is where the water has been coming in in the past). When I tore off the drywall the 2x4's were saturated with water and mold.
Thanks for the suggestion of spray foam. I have considered that but wasn't sure it if was water tight and cosmetically it wouldn't be optimal. But I could spray foam it now and in the spring cut out as much spray foam as possible and then seal it with silicone.
What about warming the brick and the metal on the door frame with a propane torch and then applying the silicone...but then I thought about expansion and contraction and am not sure if that is a great idea?
