I don't understand the problem.  The ONLY reason to leave the insert in
after streamlining it with epoxy is (as I did on my first engine) to avoid
taking the engine apart.  I had to take  that junkyard engine apart later
anyway because of BIG oil burning (cooked oil control O-rings).

My take on it - Leave it alone and drive on.
