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???

Do you hear it most when accelerating or cruising? Rod knocks are easiest to hear when the engine is spinning freely, not under power... so while cruising, let of the gas slightly and see if you hear the knock come in and out while it's loafing there as you feather it.

Taking a plug wire off CAN help locate a rod knock because without the pressure on that piston the knock will raise it's head.
