Oh, boy. Got a real problem here. Trying to remove/replace a faulty aftermarket Knock Sensor. It is only 4 years old, AutoZone Duralast house brand.
I am turning the 22MM socket, but it seems the crimped-on top piece of the sensor (with the hex on it) is just turning in the lower body of the unit. It is not coming loose. (ANOTHER reason to use ONLY GM parts for this job!).
The KS sits in a well that is a few inches deep, and there is almost NO room around the outside of the KS body, very little clearance, I can't think of any tool I can use on the OD of the body to try and turn it. This thing was only torqued to 10 foot-pounds, and there is no sign of corrosion in the well, so I would think it would come out fairly easily..
Anyone got any ideas on how I can get this thing out? I suppose I could try tapping on a chisel, on the upper/outer edge? Or, if I were to somehow destroy the sensor by ripping thew top part of it off, is there anything inside it that I might be able to dig into and turn it with a large screwdriver?
Any suggestions will be appreciated! Thanks in advance, -Jim.
