    Lightbulb Loud Tapping/Clunking in my1998 Oldsmobile Bravada?

    My 1998 Bravada started making a tapping/clunking sound, I bought the Haynes manual and have changed out the spark plugs, and checked the rocker arms with no luck. Do you have any ideas of what could be causing this. My oil pressure is good but, the thing is had it changed by someone else about 2 wks ago and drained some out to add an addative recomended by Auto Parts, and the oil was black? The engine very clean & 1 previous owner took very good care of her - she's a keeper - 178990 miles. Any Ideas, before I change the engine

    Hi Wayne,

    Well, we really can't diagnose problems from a remote location, but don't rule anything out. Recently I encountered a car that sounded like it had a rod knock, but it turned out to be nothing more than a drivebelt that had separated plies. An automotive stethoscope is also a handy tool to locate noises. If you can't pinpoint it, you might want to have a pro look at it before you pull the engine.
