Hello,

The turbo charger feed and return lines would point towards the oil feed and oil return lines.

The BMW 4.4V8 turbo engine is prone to oil leaks from these lines. Oil usually builds up inside the V valley. The turbo chargers are located inside this valley between the cylinder heads, see image below.

Hope this helps.

Cheers, Boris
