Can anyone help out with how many, where and sizes of zincs on the 3176's?? My manuals say there are 3 in the heat exchanger and 1 in the elbow. I did find a cat part number for the 3 in the exchanger but it did not list the one for the elbow. I believe the 3 are 1/4" pipe plug with a 3/8 diameter rod by 3" long. I do not know that for sure. Any advise will be much appreciated. This is on a 1996 engine.
