1999 BMW 740iL Problems

Humming Noise from fuel tank

Not only when I started the car did I heard a humming noise coming from the gas tank, it happened fairly often while driving - more during accelerating.

A fluid leak may develop from one or more power steering hose. When a leak is being repaired, it is not uncommon for multiple hoses to be replaced.

Engine Oil Leaks

Engine oil leaks commonly develop from both valve cover gaskets, intake manifold, and PCV plate after about 60,000 miles.
