I'd like to know what to look for when I take the 2.0 apart that was in Punkin. Since I've not gone into surgery of this kind I'm at a loss as to what I will see if it is a rod that was knocking.

When the engine was running a couple of us listened to it and proceeded to take a spark plug wire off one cylinder at a time to try to determine which one it was. We thought if the wire for the cylinder with the know was taken off it would cease to knock or quiet down which neither happened. Is this a way to find if it is a rod or which one it is???

Bruce, drain the oil and then pull the sump plate and the "taco" plate. Look up in there with a flashlight. You "might" see the problem. Then pull both valve covers and look/feel each rocker arm. That also might tell you something. If a valve adjusting nut/screw came loose it could be the source of the clatter. After that, engine out and begin the tear down.
