Engine Noise E39
A few days ago when I started my 1998 528i in the morning, I heard a loud knocking or Rattling sound coming from the engine. And when I turned my steering wheel to the right or left, it sounded like metal grinding to metal. But after 5 minutes or so, when the car seemed like it was warmed up, the noises were gone. This is the 3rd time it has happen, and seems to only happen in the morning.
I checked my engine oil level, and it's fine. I haven't had the chance to check my power steering fluid. Could it be my power steering? I did notice a leak coming from the power steering resorvior. Any advice before taking it in to a mechanic would be greatly appreciated.
