Preheat oven to 350 degrees F (175 degrees C). Grease a 9 inch springform pan.
In a medium bowl, mix graham cracker crumbs,vanilla wafers,lemon juice,vanilla extract with melted butter. Press onto bottom of springform pan.
In a large bowl, mix cream cheese with sugar until smooth. Blend in milk, and then mix in the eggs one at a time, mixing just enough to incorporate. Mix in sour cream, vanilla and flour until smooth. Pour filling into prepared crust.
Bake in preheated oven for 60 to 70 mins. Turn the oven off, and let cake cool in oven with the door closed for 5 to 6 hours; this prevents cracking. Chill in refrigerator until serving.
