1997 993 Spark Plug Installation


Vehicle Information: Model: 993; Year: 1997; Body Type: Cabriolet; Total Mileage: 31000;

I've experienced the same problem as a prior post on installation of spark plugs, coincidentally in the same area, #3 Lower Plug, except that I dont think it has been cross-threaded. The old plug came out much "faster" than the other plugs and the new one went in with much less turns of the wrench to reach the torque value. I removed and replaced the new plug several times. But when I shine a light into the head, the plug appears to be angling downward instead of sitting perpendicular to the head, as with the rest of the plugs. Accordingly, the plug wire does not fully engage the plug. Unlike the prior post, I've removed and reinstalled the plug several times with no evidence of cross-threading or filings. The old plug did not show any damage either. I had no performance issues previously that I was aware of. Im thinking to remove the valve covers to examine more closely, but then again, Im not sure what I would do about it once Im into the head, other than replace the valve cover gasket.Any help would be as always appreciated.
