02 A6 2.7T Q Tip

I've been noticing a little oil leaking in area under the engine cover. Seems to be building up in bi-pipe, y-pipe, DV area. Just replaced my DVs about two weeks ago. I fear cranking the hose clamps any tighter than they already are. I had noticed a little oil there before and there was some in the hoses when I changed the DVs. I understand a little is to be expected, but how much is too much?

P.S. I also suspect that the oil is overfilled. Getting ready to do TB and related parts, alternator, and oil change with the correct amount this week. Is there anything else I should be looking for while its apart based on what I'm seeing above?

 

Where under the engine cover?

 

^^^

right around the connections from the bi-pipe to the DVs and throttle body boot. I know the TBB is a common cracking/fail point but mine appears to be in good condition

 

I know very little about the 2.7, but isn't all that on the rear of the engine? Could it be from the cam seals/valve cover et al leaking down onto other stuff?
