1997 Chevy Cavalier 4 cyl Two Wheel Drive Automatic 140, 00 miles
I have a 1997 Chevy Cavalier with a 2.4 Liter engine. My problem on it is that as soon as the engine starts running until the engine is cut off there is a knocking sound coming from the engine. What is the most common thing that this is and what do I need to check? As long as the engine is running it knocks. It sounds like a nut is loose on the inside of the engine.
