Not sure of the spelling but I've seen this in posts being used before spark plugs are removed. I have a 1999 v-6 f-150 2 wheel drive and want to replace the plugs myself. I keep hearing about broken plugs and big bills to replace the plugs but I think that may involve V 8s. I THINK my plugs have not been changed and have 114,000 miles on them.
Sould I use seafoam?
Will the plugs break
Any help will be good

You should have no issues changing the plugs in that v6... They are rather easy to change. Be sure to use Motocraft plugs!

 

Our gen trucks just have the problem with spitting out plugs if not installed properly. Breaking off Is with the 04- late 07

 

The V6's have zero spark plug issues
