Hi Group: Hope someone here can help me with this question.

I've got a minor leak in my exhaust manifold of my 2000 civic. I'm wondering
whether I'm doing my motor any harm by not having it repaired right away. It
doesn't seem to be affecting performance in any way, but I've been told by a
mechanic that it's there and I think I can hear it.

I'm also curious about the cost of repairing it. I'm in the Toronto area of
Canada.
