LIFTERS

2002 Cadillac Escalade

Engine Mechanical problem
2002 Cadillac Escalade V8 Two Wheel Drive Automatic 159400 miles

My engine began to make a noise like there is something loose in the head (top left) of the engine. It sounds like a flottering sound and as I acellerate the noise is faster and louder?

If you can determine that it is rhythmic with camshaft speed, it could be lifter, rocker arm, or something of that nature. To narrow it down(not isolate), you would first remove the belt, and then kill cylinder power one at a time. You could do this by disconnecting coils or injectors. That may or may not make a change. You can also run the vehicle with the cam cover removed, but it is messy.
