I recently was confronted with a noticeable "gurgle" sound from behind the dash area of my 2007 Z06 Corvette. It was audible at idle and continued for a second or so after turning the car off.
After a bit of research on the forums, it seemed like the most likely explanation was that the dry sump oiling system was overfilled; upon checking it, it was indeed at least a quart high. Apparently the manual's admonition to ensure that the oil is WARM when reading the dipstick was correct.
Not wanting to drain it and start over, I tried a hand pump (no luck) and eventually resorted to a 3/8" clear plastic tube stuffed down into the dry sump tank which I used to siphon the extra oil out. Used oil is carcinogenic so clearly you need a safe way to initiate the siphon. Even with the oil warm it took about 20 minutes for the extra quart to dribble out, but once I was done, problem solved. No more gurgling noises.
