Narrative:
While doing an a-chk on aircraft X, I found, in my opinion, excessive metal on the #2 engine starter chip detector. So I went ahead and changed the #2 starter. I ran the #2 engine at idle, reopened the cowls and inspected for leaks. There were none present. After arriving at next station, #2 engine had excessive oil loss. Cause was determined to be faulty o-ring on #2 starter. O-ring was not found. That station replaced the o-ring on #2 starter. No other occurrence of oil loss problem.
