Engine Mechanical problem
2001 BMW 540i V8 Automatic
when changing and replacing the spark plugs, I found engine oil in one spark plug tube. I found it on only one spark plug tube #4 (one out of 8 spark plug tubes) of the engine.
what is the probable cause, and how would you fix it?
have the same problem?
