1998 BMW 740iL Problems

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

Leaks are known to develop in the cooling system. It is common to see more than one part recommended for repair/replacement due to overlapping labor and the use of many plastic parts in the system.

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.
