Zevachim 3:3-4

Zevachim 3:3

If one slaughters a sacrifice that is not fit to eat with the intention to eat it in the wrong time or place, or a sacrifice that is not fit to burn with the intention to burn it in the wrong time or place, it remains valid, though Rabbi Eliezer declares it invalid. If he intends to eat less than an olive-sized portion of that which is fit to eat in the wrong time or place, or to burn less than an olive-sized portion of that which is fit to burn in the wrong time or place, the sacrifice remains valid. If he intends to eat half of an olive-sized portion and to burn half of an olive-sized portion in the wrong time or place, the sacrifice remains valid because eating and burning do not combine.

Zevachim 3:4

If a person slaughters a sacrifice intending to eat an olive-sized portion of its skin, broth, seasonings, scraps, bones, sinews, hooves or horns after its proper time time or outside of its proper place, the sacrifice remains valid. One is not liable to piggul (improper intentions), nosar (leftover sacrifices) or ritual impurity because of these things.
