Anyone in Brooklyn with 3.0?

[Roman D]

Hi guys, anyone in Brooklyn or near with E53 X5 3.0? I would like to listen to the sound of the engine - I think mine is hissing, passed the smoke test @ BayDiagnostic and they really pumped it up - I think it sqooshed some oil out of rear crank seal (which is NEW) under pressure, NO Check Engine light but I don't like the way it sounds. I never had a BMW before so I would like to hear what is "Normal" The reason why I am looking in to it is because when I start the engine and take off - car is very energetic, clutch bites right in and engine pulls smooth and strong, next traffic light - it becomes lazy-er....
