Engine Mechanical problem
2001 Ford Expedition V8 Four Wheel Drive Automatic 104K miles

My 2001 Ford Expedition started making a clicking/knocking sound from the engine compartment. I have never had any oil problems, no oil leaks, etc. I checked for any loose items...nothing found. When the vehicle is driven the sound gets louder when accelerating. I suspect that a rod may be bad but the engine runs great, good power still, etc. The vehicle has 104K miles on it. Are there any checks I can perform to determine what may be the problem? It doesn't make sense that the rod/rods may be knocking when there has never been any oil problems with the vehicle. Please provide advice/assistance....send suggestions to my email: donald.fisher@us.army.mil
