Are any of you having this problem? I have 4.2L V6 in truck, broke 4 plugs but my mechanic was able to get them out without to much trouble. Did some surfing and found this is a widespread problem.
Are you guys having problems with seized sparkplugs? My 97 F150 with 4.2L V6, had a check engine light last week, brought it in and it had a misfire at #1 plug. Mechanic said all the plugs were seized. He got them all out but broke 4 in the process. Did some surfing and found this a widespread problem. Any ideas?
Hope your mechanic used anti-seize on them when he install the new ones
And yes Ford does have a problem with some of them.
Some customer oriented dealers do recommend to customers to have them checked at customer cost (I think), before warranty runs out.
Just to avoid future problems for their customers
Thats smart move with anti seize
I would do it every 60k or 2 years, that is my plan
Same with oil changes my manual tells me every 12k I do it every 10k
Don't forget Manual will only give you Min requirements
to keep your warranty intact, only.
you where one of the lucky ones, some of the guys I know had to pull their heads to get it fixed
shit i guess i am gonna have to do mine asap since im at 63k ,some guys on the f150 site are using some kinda of penetrating lube on the plugs to get them loose before they try to wrench on them,i guess they pre-soak them ,then try to break them loose
Nothings worse then haveing aluminum heads. My heat stops when I feel the plug get really tight half way out, I sit their for about 30 minutes turning the plug in and out trying to save me from pulling the head off.
One time I could do anything but keep turning the plug out and almost cried when I saw all the threads come with the plug...Customer was mad and didnt understand their was nothing I could of done different
