[s-cars] Rear main seal leak - try dino oil again?

[DGraber460 at aol.com]

We have a 98 A6 2.8 with the dreaded rear of the head leak that drips on  the 
exhaust and smells like a "trailer trash" oil burner. It has done this for  
3-4 years and the cure (I'm told) is to pull the head and re-peen the small  
steel ball into the head. No plug, no threads , and no way to service this  
pinnacle of superior German design except to pull the head to fix one small  leak.
I switched to dino oil (Valvoline) and it reduced the occurrence  
significantly. Recently I had a lapse of memory and filled it with  synthetic. Within 
very few miles it started leaking again very badly.  Switched back to dino, and 
it has abated once more. This is not a car  I will put in my will, a turbo, or 
any such, so for now, I'm OK  with the extra deposits that will also result.
So from where I sit it, would be worth a shot.
