Engine Mechanical problem
2004 Ford F150 V8 Four Wheel Drive Automatic 32000 miles
I have horror stories about changing spark plugs in the 5.4 triton, that they break off in the head. Some people have told me it is the carbon that builds up on the bottom of the spark plug that makes it break. If so is there any treatment that could be used to loosen the carbon or what causes it. Or is there some other cause. How do I go about changing the plugs
You have to remove the coil before you remove the spark plugs in all, about a two hour job.
I have been told the engine would cool off during that time wouldn't it
have the same problem?
