I am attempting to R&R spark plugs again. My first time was 60k miles ago with no issues. Now the drivers side front plug isn't cooperating with the socket. The socket keeps slipping off the plug. I have used different length drivers including my 16" long torque wrench with no success. It feels as though, no matter how much down force I use, the socket still slips off and does not turn the plug at all. It's as if the socket does not have enough bite on the spark plug to effectively turn it. I know I have the right sized driver for the plugs however this issue still remains.
I have heated the engine to operating temp, sprayed PB Blaster into the well - no success. I have removed the coil overs and sprayed the plug well after the engine heated up - no success.
With the above stated, is it safe to use an impact driver on the spark plug to free it up? Will an impact driver damage the head? I know that the plug may separate which is ok because I can use the plug extractor. Alternatively, what should I expect to pay for spark plug R&R knowing that the repair shop will sell me new plugs at their retail price?
Any ideas or suggestions would be greatly appreciated.
