The breather box is part of the PCV system BUT you probably have its seal (at the block) leaking OIL right? I fail to see how that oil leak is "emisions related" just because it's technically an emisions part. VIP covers that as the oil leak isn't an emisions part failure. The breather box part itself isn't bad, not replaced, just the seal.
The fuel door hinge isn't hard to replace. You use a punch to tap the old plastic pins through and then a slightly larger punch to tap the new ones (included) into position, then swap the door.
