I have a 2008 A4 Quattro 2.0T. I'm rebuilding the engine head and had a question about one of the holes on the block. Please see the attached pic. I had a tiny piece of putty fall into this hole and am wondering if I need to get aggressive with removing or finding it. This hole moves oil and connects to a bolt hole on the head with another connecting channel attached (where I assume oil drains around the head bolt). I verified the channel has an opening to the right about 9-10 cm. down into the block. Oil is standing in this channel and my concern is that the tiny piece of putty is blocking the outflow or passageway in the block. I'm I acting like an over-paranoid idiot here or do I have an issue? Thanks a lot

 

If it's an oil passage,you better get that piece of putty.
The last thing you want to do is put it all back together,and within 10 miles
break down AGAIN.
Good Luck!
