The mechanic told me not to worry about it because the car has 155,000 miles on it and it would be expensive to replace.
Why would it be expensive to replace and where is this valve located?

I think your mechanic is wrong in that the valve is not really an expensive part, and it is not hard to replace.
If it is bad, the valve is located on the passenger side of the engine, near the back. It looks like a flying saucer with a rubber hose going to it, and a small diameter metal pipe exiting to toward the back of the engine.
Last, if you don't fix the problem, you will not be able to pass a smog inspection, should your state require one.
