The dealership states: "breather box is restricted will require breather box, hoses, seals, and gaskets along with oil pan reseal for $1727." Car has 100500 miles. I can't find information about a breather box. Does this sound right? Thanks in advance.

If the breather blocks up it builds up crankcase pressure causing seals to leak and oil to contaminate the timing belt even if the cam or crank seal starts to leak.

I would be cautious about resealing the oil pan. When the breather box leaks (which is common) it can look like the oil pan is leaking, but the oil pan seals rarely leak.
