1999 ford 5.4l

Not exactly sure what you mean. The plug is broken? Replace them all.

Known issue with this engine. Replace that cylinder head... not a one-day DIY job.

The best way to do this repair to use an insert in the spark plug hole. This repair does not require removal of the cylinder head. It can be done in the vehicle. If you have a mechanic that you can trust you may want to go ahead and install inserts in all of the spark plug holes. The cost of replacing all of them will still be less than replacing a single cylinder head you can find the repair kit at the link below. This is a reliable repair that should last life of the engine if done correctly.

thank you. i took the time to locate the tool kit, it runs about $427.00 it sounds like agood deal. i will be trying this. rather than spending a $1000.00 on head work. but i will be looking for a used motor to rebuild.
