whitewashing the trunk won't help any....nor will any other "Stuff" you apply to patch any holes/splits. etc... Limbs breaking off during weather events are just part of a tree's life....nothing you can do to prevent it and nothing to do to fix it. Tree wounds heal best by applying nothing. As far as sap: not sure what's going-on. Are there holes in/around the trunk? If so, the birds are mining for the insects. If not and you merely have sap flow, the tree has a wound of some sort (can't tell by the pic). That's not a very old tree, so sap is somewhat unusual. If there is no frass (super fine sawdust) mixed in the sap, then you have some sort of internal issue going-on and no bugs - normally not a big deal. The biggest test will be next spring when all the trees break bud: if the top looks good and the leaves come-out full sized and on-time, then you don't have much to be concerned. If leaves are off-color, smaller than usual, or sections of the limbs don't have foliage, then there is probably something wrong with the root system. But my initial guess is it's no big deal. This is  the wrong time of year for accurate tree diagnosis (they're hibernating). If you want to take a few close-up pics of the trunk, send them back and we'll take another look. That's about all I can say right now. 

Steve, Thanks for your reply. I know I should have taken close-up pictures of the tree trunk so here they are. I checked for any signs of insect damage but again it is too early in the year for any activity. However, I will monitor the trunk during spring and summer. Too bad I can't put a big spray bandage on the places where sap is appearing. Ha Ha. I'm also sending a good picture of the tree as to why I want to save it as mentioned in my first email. Thanks again, Shirley in Roseburg, Oregon

Ok....I don't think you have any bugs in there. The stain is in the crotch of the tree - an area you will often see some sap or color or different bark patterns because the tree is "splitting" at teis point. It wants to be 2 trees, but they'reheld together. If you opened up the tree, you'd see a curly wood/off-colored area where the two limbs come together. I'll show it to our "expert" and get his opinion. But for now, don't fret.....nice looking tree.
