Stuck Spark Plug
1973 F250. The second spark plug from the front on the passenger side will not come out with a 1/2" drive socket and wrench. Whats the deal with that? I am afraid of stripping out the threads on the head. That seems like it would really suck. Should I just apply some massive torque and see what happens or what?
Thanks in advance,
Abrams

Try taking it out when the engine is hot!
Before applying massive amounts of torque I would use a rocking motion with an impact wrench on the lightest setting and maybe turn down the psi at the compressor.

Just my 2 cents, Like said above, try using some Liquid Wrench, Put on a heavy coat on it..and let it set.. Your not going to hurt the theads in the head, because the plug is softer metal than the head is.... Good luck!!

Is the plug really a softer metal than the heads? I just remember somebody having a spark plug strip out a head one time... maybe it was aluminum.
Thanks for all the help. Wish me luck.

When I bought my '70, I had to use an impact gun to get those plugs out. I didn't use and solvent, and the engine was hot. No damage done, for what it's worth.

The most important thing is to do it with the engine hot. The block will be at the max. expansion and the plugs will end up being cooler then the block after it sits for a few minutes because the block will retain its heat. The thread on a spark plug is designed to compress so it seals the combustion chamber. As such, using WD40 etc etc does very little to free a frozen plug. I would vacuum the hole afterwards to get any slivers of metal from the thread out of the engine.
