Replacing Spark Plugs
Hello, I am replacing the spark plugs on my '97 F-150 with the 4.6. I have replaced 6 of 8, and the last two are giving me the same problem: I can't fit the spark plug socket onto the nut of plugs #4 and #8. Being that those two plugs are at the back of the engine and underneath the firewall, I am unable to see into the well to see exactly what is going on (dirt, stripped plug, etc.). Any suggestions are greatly appreciated.

I was able to get the plugs out. As said, it was dirt around the nut of the plug. I heard that a few others used a 3/4" copper pipe and cut teeth into it to work the dirt free and blew the well out with compressed air. I gave it a try and it worked. Thank you all for the welcomes and suggestions.
