Another 930 leakdown question

I have a low miles (36K) 930 that has had engine gone through less than 10K miles ago. I have an issue where 5 of 6 cylinders have leakdowns of 4-8 % and one cylinder is 30 %, leaking out exhaust of #4. Based on a quick search of this topic I put a couple of bottles of techron in car and went for a spirted drive. I will leakdown "bad" cylinder again tomorrow and pull valve cover and do the tapping routine that has previously been reccomended. Best case senario is problem has been resolved, just curious what worst case senario is, motor runs well doesn't smoke or use oil, has excellent oil pressure.
