No, but they did have the head gasket and water pump for my 2005 4Runner.
Expanding foam is your best bet. After the foam is done expanding/drying, shave down the foam that cleared the sides of the brick w/ a putty knife, then paint it / spackle and paint it.

Edit.... I just read where this is on the bottom of the porch above you.... that needs to defy gravity. Plastering with a cementitious overlay would probably work, but I would start thinking about something decorative.... like an embossed plastic or aluminum where the moisture does not bother it much.... more of a soffit material. Depending on what you use, you may have to glue up some felt tar paper to stop any chemical reaction, but an epoxy paint as a sealer would probably work just as well.
You hate to buy a whole bag of mortar for a hole or two, but take along a zip lock bag and you can often find a broken bag at the box store for cheap, or they will give you a hand full. Or, catch someone doing brick/block work and ask them for a hand full. You could use Portland, but it is not water proof like mortar is.
